What's New, WIP 2011-07-13 (13-Jul-2011)
Funciones mejoradas:

• BlockManager
  • Added Select button that clears the current selection set and selects top-level instance references that match the ones currently selected in the Block Manager.
  • The Block list now selects blocks that match top level block references that are selected when the dialog is initially displayed.
  • All options now work with multiple select.
  • The Count output now works with multiple select and displays in a dialog that allows you to export the report to a CSV file or copy the results to the clipboard.
  • The Referenced By output now works with multiple select and displays in a dialog that allows you to export the report to a CSV file or copy the results to the clipboard.
  • Delete works for multiple items.
  • Export works for multiple selected items. If more than one item is selected, you are now prompted for a folder to export the selected blocks to; otherwise, if a single file is selected, you are just prompted for a file name. If more than one file is selected, an overwrite warning dialog will appear as needed that lets the user decide what to do with the name conflicts, it works similar to the overwrite warning in Windows File Explorer.
  • New block Preview for the currently selected block.
  • Multiple select now works for all Block Manager functions: Export, Delete, Update, Select, Count, etc.
• Insert
  
  • Disabled the Link button when inserting non-3dm files, since we currently only support embed and embed with update for these files. These controls should be enabled and the check box should work.
  • Enabled Link and Embed controls when inserting 3dm files. If inserting a block, make these controls match the current block definitions settings.
  • If the block in the inserted file has the same id and the objects it uses have the same ids, the existing block definition is used; otherwise the block from the file inserted file is used and the name is incremented.
  • Non-3dm files can no longer be inserted with the Link option. These files can only use the Embed and Embed, Allow update options.
• Save:STEP: Surfaces are no longer shrunk on export.

• Block: Block definitions created by a Paste command were not deleted when the Paste command is undone. This is fixed.
• BlockEdit: The warning message about locked or hidden objects incorrectly appeared when objects were deleted. This is fixed.
• BlockManager: The Select button incorrectly selected locked or hidden instance references. This is fixed.
• Import: Block definitions were not correctly handled when a file was imported. This is fixed.
• Insert:
  • Incorrectly ignored the ModelBasePoint in an inserted file. This is fixed.
  • Several problems with duplicate block names have been fixed.
• Intersect: A problem with intersecting blocks containing extrusion objects has been fixed.

• BlockManager: Dialog box information about the existence of hidden blocks has been improved.
• BlockManager: If block instances are selected in Rhino when BlockManager starts, the corresponding block definitions should be selected in BlockManager. A new Select button in the BlockManager dialog box selects instances of the block highlighted in the list.
  
• Hatch: In Properties, the rotation and scale now update when you press Enter for the field.

• MoveHole: Ortho was ignored and keying in a dimension produced erratic behavior in the feedback and an unexpected result in the placement of the hole(s). This is fixed.
• Toolbar: Setting the Windows font size to larger than normal affected the ability to change the size of a toolbar. This is fixed.

• ExtendSrf (1)
• Localization (5)
• WireCut (1)

• CrashDump (2)

• CrashDump (1)

• Block: Block names are now displayed as part of their object Properties.
• BlockEdit: New dialog box prompts prior to starting another Rhino session to edit top-level, linked blocks and added a command line option to control display of the warning dialog so that it can be turned back on if somebody chooses the "Don't ask again" checkbox.
• BlockManager: The block infrastructure in Rhino now automatically saves both relative and absolute paths, and uses both as hints when searching for files. Therefore, the "Use relative path" checkbox has been removed from the BlockManager > Properties dialog box.
  
• BlockManager: Inserting a block defined in a linked model is no longer allowed. The BlockManager command has been updated to filter these blocks out.
• Insert: Dialog box changed to reflect status of linked and embedded blocks.
• Insert: When inserting a .3dm file as a block, if a block of the same name already exists in the model, the block name is incremented with a number.
• Pipe: History is now supported.
• Pipe: New Thickness option sets the pipe wall thickness. Negative numbers make the first radius the outer core.
• ReplaceDetail: No longer repeats.

• BlockEdit: When using the Add button, the block was incorrectly removed from the file. This is fixed.
• Bongo: Rhino 5.0 WIP 6/17/2011 crashed while loading Bongo 1.0 SR7. This is fixed.
• DimDiameter/DimRadius: In a detail, hidden objects were incorrectly being selected. This is fixed.
• Insert: Command-line options have been updated to match the dialog box.
• Insert: The Insert dialog can now be expanded horizontally.
• Insert: The style "Link & Embed" has changed to an "Allow update" option for Linked blocks.
• Insert: When inserting an .dwg file, nested blocks insertion points were incorrectly placed. This is fixed.
• MaterialEditor: Plug-in materials were being lost. This is fixed.

• BlockEdit: If, while editing a block, some objects are hidden or locked, when the block is saved, a warning message about the hidden or locked object displays. A Yes response deletes the hidden or locked objects from the block definition. A No response shows or unlocks the objects and keeps them as part of the block definition.
• BlockEdit: The block editor will now spawn a second Rhino session automatically when the selected block is a linked block.  If the selected block includes references to linked blocks then selecting the block in the tree will prompt you to edit the block definition externally.
• BlockEdit: You can now double-click on a block instance to launch the BlockEdit command.
• Fillet: When filleting a polycurve by picking an arc segment, and the arc needs to be extended, the default extension incorrectly was a line, this is now an arc.

• Gumball: Dimension feedback and units were incorrect when scaling. This is fixed.
• Leader: Text justification was incorrect. This is fixed.
• Open:FBX: Rhino 5.0 WIP 6/17/2011 crashed while reading FBX files. This is fixed.
• Open:SolidWorks: Rhino 5.0 WIP 6/17/2011 crashed while reading SolidWorks files. This is fixed.

• BlockEdit: New command. Allows editing a block in place to change the geometry and sub-blocks.
• CreateRegions: New command. Takes a nonmanifold polysurface and replaces it with all solid manifold regions defined by the surfaces of the input. If no solids are defined, the input will disappear. It is under develpoment and the interface will change.
  

• 3D Printing: 3-D printer plug-ins now load on demand instead of at startup.
• ApplyDisplacement: A Preview button has been added to the dialog box.
• BackgroundBitmap: A new 1to1 option has been added after the first corner has been picked.  The width and height of the image in pixels and the resolution of the image in dots-per-inch is determined and the image automatically scales based on the model's current unit system.
• BackgroundBitmap: If the current viewport has no background bitmap, the BackgroundBitmap command now automatically runs the Place option and goes to a File Open dialog box.
  
• Block: When importing a block of the same name as a block already defined in the model, the block name is incremented.
• Delete: Now supports deleting polysurface, extrusion, and mesh faces. Select subobjects, and press the Delete key.
• InsertKnot: New Undo option.

• BlockEdit: Incorrectly unlocked previously locked objects. This is fixed.

  1. At the relative path location
  2. In the same folder at the current model
  3. Paths in the Rhino Search Path
  4. Warn that the file could not be found and offer the option of browsing or cancel.
• BlockManager: When a file is inserted as a block instance and Embed is chosen, the BlockManager no longer shows any path to the file.
• Blocks: When blocks are inserted as "Linked," the Layer dialog box indicates the file name with the layer names as child layers.
• BoxEdit: Now displays in a docking tab.

• BlendCrv: The preview color was incorrectly always set to black. This is fixed.
• Block: Curves with arrowheads were not drawn correctly when they are inside blocks. This is fixed.

• Gumball: Added a new sticky-in-session setting for gumball mode, adjustable from status bar Gumball context menu, and the bunnytail menu. With this setting gumball is decoupled from drag mode.
  
  • Modes:
    CPlane: all gumballs are aligned to construction plane.
    Align to object: the gumball is aligned to the object for planar surfaces and planar polysurface subobjects, extrusions, lights, curves, polygon mesh subobjects, and control points. For other things the gumball is aligned to construction plane.
    Align to world: all gumballs are aligned to world xyz directions.
    Reset gumball: restores the default placement and orientation for the gumball in the current mode.
  • For whole objects, only one gumball per object can persist. If you change the mode, and then change back, the possible relocation of the gumball is lost. 
  • For subobjects, the gumball never persists. Relocation sticks for only as long as the specific gumball is visible.
• WebBrowser: New scripting toggle has been added.

• ApplyEdgeSoftening: Texture mapping did not update when edge softening was on. This is fixed.
• CursorTooltip: A random number was displayed with the Tab direction control. This is fixed.
• Isometric: Undo did not immediately return the view to the previous view. This is fixed.
• MoveFace/MoveEdge: Several bugs have been fixed.
• PictureFrame: Updating the properties of a copied pictureframe incorrectly updated both the original and the copy. This is fixed.

• Docking tabs: The minimum height was deemed to be too tall. This has been improved.
• NamedView: Viewports are now unlocked when restored from locked named views
• WebBrowser: The browser window now docks.

• DimAngle: The Print Width was ignored. This is fixed.
• Docking Tabs: Material, Environment, and Ground plane tabs did not remember between sessions that they were open when Rhino closed. This is fixed.
• ExtrudeSrf: In Wireframe views, objects were incorrectly being meshed during the extrusion process. This is fixed.
• Extrusion objects: Render meshes did not correctly save their texture coordinates. This is fixed.
• NamedView: Cameras can no longer be copied.

• Properties: Deselecting multiple objects should be faster now.
• Render: Material swatches now render without shadows. It did not work very well and made the swatches render too slow.
• Select: It is now possible to completely deselect objects with selected subobjects with Ctrl + click or window/crossing select. The idea is to make deselection easier if you have subobjects on multiple objects selected.

• BlendCrv: Esc did not properly cancel the command. This is fixed.
• BlendCrv: Symmetry was not maintained when continuity was changed. This is fixed.
• Dimension: Dimensions in layouts did not update correctly when the scale changed. This is fixed.

• 64-bit Plug-ins Must Be Updated: This build of Rhino 5.0 x64 is not compatible with previous 64-bit plug-ins. Please contact your plug-in vendors for updated 64-bit plug-ins.
• RhinoScriptEditor missing from build: This build does not have RhinoScriptEditor; a new build will be released this week that includes the RhinoScriptEditor.
• Smooth: a new FixBoundaries option keeps edges and endpoints from being included in the Smooth operation. 
  Meshes: Vertices along naked edges will not be modified. Curves: End control points will not be modified.
  Surfaces: The control points along the boundaries of the surface will be modified. The edges and trims of trimmed surfaces will still be modified as they are now if the don't coincide with the surface boundary.
  Notes:
  
  • If all of the object control points are selected, Rhino perceives this as the whole object being selected.
  • If the FixBoundaries checkbox is checked, this will have an impact on closed curves and surfaces with seams or singularities that may not be desirable.

• Extrusion objects: Extrusion subobject prepick should now work, and prepicked subobjects should work as input in commands, similar to polysurface subobjects. The subselection should persist when command ends. You can also drag/transform/gumball edit extrusion subobjects. The first edit converts the object into a polysurface.

  • Selected object count
  • Selected object layer
  • Number of off layers
  • Relative coordinates and angles
  • Curve parameter/UV coordinates

• Angle constraint in elevator mode: Angle constraint can now be used for finalizing the pick in elevator mode. An example: Run the Line command, pick one point, move the mouse and activate elevator (press Ctrl) for the second point, type <30. A line is drawn at 30 degree slope off the construction plane, ending on the elevator line.
• Autocomplete: New setting - Tools > Options > Appearance: Use fuzzy autocomplete. When enabled, inline autocomplete suggests the most used candidate ( LI most likely autocompletes to Line instead of LimitReferenceModel), and the autocomplete menu contains best partial and inexact matches. When disabled, autocomplete uses the first letters of the command name in an alphabetical list.
  
• BlockManager: Blocks nested in linked blocks will no longer appear in the Block Manager list.
• BooleanDifference: Prompts changed to be more instructive.
• FilletEdge: Continuing improvements for special cases.
• Hatch: A selection of standard hatch patterns now always loads with Rhino.
• Hatch: Hatch patterns are now previewed as they are applied with the Hatch command.
• MakePeriodic: New Smooth option at the first prompt controls kink removal. With Smooth=Yes (default) the command smooths any kinks in the curve, and moving control points around to make a "nice looking" curve. With Smooth=No, control point locations are not changed or changed minimally (only only point may move) and basically just the knot vector is periodized.
• PlanarSrf: History is now supported.
• Sphere > 4Points: Work flow has changed slightly to clarify use of the Radius option.
• Unwrap: Command options: Apply, Edit, and Cancel added.
• UVEditor: Minor revisions and improvements.
• Video clips on 64-bit systems: Will now play if you have Adobe Flash Player "Square" installed:  http://labs.adobe.com/downloads/flashplayer10_square.html. If you do not have Square installed, you will be directed to the Adobe web site where you can download the new player.

• FilletEdge: The PreviousEdgeSelection option incorrectly did not work properly if the radius option was changed. This is fixed.
• Groups: Control+Shift+clicking to select block that is in a group did not work. This is fixed.
  
• Hatch: Changing the current layer during the hatch command failed to place the hatch on the new current layer. This is fixed.
• Rectangle: Pressing the Shift key did not work properly in Rectangle Center to constrain a square. This is fixed.
  
• SelLayer: Using the layer name: "Parent Layer::Sub Layer" did not correctly select the sublayer. This is fixed.

• Light-Weight Extrusion Objects: New feature. Rhino 5.0 has a new lightweight extrusion object that uses less memory, meshes faster, and saves smaller that the traditional polysurface used in Rhino 4.0. In Rhino 5.0 WIPs released on or after October 12, 2010, commands like Box and Cylinder create lightweight extrusion objects. Other commands like Pipe and ExtrudeCrv make lightweight extrusion objects when possible and make traditional polysurface objects when the resulting geometry is too wiggly to be handled by a lightweight extrusion object. For more information, see: http://wiki.mcneel.com/rhino/rhinov5status_extrusions

• Properties: Advanced Texture Preview. The advanced texture preview supports the following improvements to standard texture display:
  
  • Decals
  • Multi-channel mappings.
  • WCS and WCS-box texture types (ie - 3d procedural textures)
  • Improved spherical and cylindrical display for low-poly meshes (especially at the poles).

• AutoGumball: Now pays attention to World and UVN drag modes set with DragMode command. In World drag mode the gumball is always aligned to the world axes. In UVN drag mode gumballs for single mesh/surface control points, and single mesh vertex and single mesh face gumballs are aligned to surface normal and UV directions.
  
• Dimension Properties: A new Import button imports dimension styles from other models.
• MaterialEditor: When a material that is being shared by more than one object or layer, a warning is displayed.

• Display Engine: Meshes were drawn in linked blocks when the layers were off. This is fixed.
• Display: Offset texture coordinates displayed differently in Rendered and Rendered Shadows display modes. This is fixed.
• Properties: Macros for setting material properties did not work if the Properties dialog was not in front in the session. This is fixed.

• Text/Leader: A new Field button has been added to the dialog box that displays a list of the available fields with descriptions.
• Text: New Field option supports text fields.
• ViewCaptureToFile:
  
  • If the command is NOT run via the scripting mode (i.e., ViewCaptureToXXX), then the width and height are taken from the active viewport's width and height.
  • If the command is run via the scripting mode, then width and height are taken from whatever values are entered (appear) in the command line.

Once you have picked the subobjects to drag, you can start dragging by grabbing the object anywhere, not just the selected subobjects.
  
• SetDocumentUserText: New command. Plug-in deveopers will use this to attach their information to documents.  The Rhino commands SetDocumentText/GetDocumentText are necessary so scripters, developers, and users can view information that is in thier document.
  
• Technical: New viewport display mode. Uses real-time silhouettes and intersections, creases, borders, blended shaded and rendered display. Objects behind other objects are occluded.
• TextField: New feature. Text fields are a new feature for text and leaders. Text fields are "formulas" that are evaluated while Rhino is running and the result is displayed in the text. All text fields are in the syntax of %<field and options>%. When a formula cannot be evaluated an error string of #### is displayed. 
   
  When typing text, use the field syntax.

• CommandHelp: Now displays on a docking tab.
• Explode: When Explode is applied to an extrusion object, it is exploded into single faces as if it had been a surface/polysurface all along.
• ExtendSrf should now work on trimmed and untrimmed surfaces.
• Lasso now works in 3D instead of 2D and allows you you change the view (panning parallel views is the one that will always give predictable results) while selecting and should work even if the lasso region goes partially outside the viewport. In addition, the lasso feedback is now the Tracking color.
  
• Lasso: Now uses Rhino's Tracking lines color set in Options: Appearance: Colors.
• Loft: New SplitAtTangents option specifies whether resulting surfaces will be one surface or a polysurface if the input curves are joined tangent curves.
• NewFloatingViewport: New Drag and drop. You can now create a new floating viewport by dragging a viewport title outside the Rhino window.
• Notes is now a tabbed dock bar.
  One thing to consider - the tab disappears when a new document is opened because this is the way the old notes docker worked.  Does this still make sense?  It's a bit odd when the tab suddenly disappears.
• Osnap: Right clicking an osnap in the Osnap toolbar the second time will now restore the previous Osnap set, if there is one. Otherwise it will work like it used to, selecting all but the one you clicked.
  
• Osnap: Vertex object snapping now pays attention to CullControlPolygon. If control polygon culling is on, Vertex osnap will not find mesh vertices from the back facing side of a mesh.
• RailRevolve: New SplitAtTangents option specifies whether resulting surfaces will be one surface or a polysurface if the input curves are joined tangent curves.
• Revolve: New SplitAtTangents option specifies whether resulting surfaces will be one surface or a polysurface if the input curves are joined tangent curves.

• SelPictureFrame: New command. Selects objects created with the PictureFrame command.

• Divide: A new GroupOutput option allows grouping of resulting point objects.
• Drag and drop any supported file type that makes textures (bmp, png, jpeg, hdr, exr) does one of the following things:
  
  • If the drag is onto an object: The material on the object is either changed to set the diffuse texture to the dragged texture, or a new material is created with that texture in the Diffuse slot.
  • If the drag is into space: A dialog box appears with three options: PictureFrame, Wallpaper, Environment.
• DragMode: The options in DragMode now work as toggles. If you select a mode that is already the current mode, the mode is reset to CPlane.
• DragMode: The new ControlPolygon options allow dragging a curve/surface control point along the control polygons that connect to it.
  
• Extrude: New SplitAtTangents option allows creating polysurfaces split at tangent arcs and tangent arcs to lines.
• MoveUVN: New Along (control polygon) extensions mode. The control point will move along the imaginary extensions of the control polygon.
  
• Osnap:Vertex: Now pays attention to control polygon culling setting. Vertices that would be culled if control points were on are not snapped to.
  
• PictureFrame:
  • PictureFrame materials are now shown only in the Properties dialog, not in the Material Editor.
  • The Material Properties dialog box now displays the name of the bitmap.  
  • SetObjectDisplayMode no longer affects how PictureFrame objects display. PictureFrame objects now always use Rhino's default "Rendered" display mode.
  • The Self-illumination setting has been changed to a Yes/No toggle.

• ExtractSrf: Using the Copy option incorrectly unhighlighted the already picked faces, but they remained selected. This is fixed.
• ExtrudeCrv, ExtrudeCrvToPoint, ExtrudeCrvTapered, ExtrudeCrvAlongCurve, ExtrudeSrf, ExtrudeSrfToPoint, ExtrudeSrfTapered, ExtrudeSrfAlongCurve: Lots of internal changes. Please report anything that no longer works.
  
• Layer Material Dialog: The dialog did not allow creating a new material or editing of the chosen material. It was also not clear which material is actually the chosen one. This is fixed.
• MaterialEditor: In Expert Mode, on any texture type, the controls on the Output Adjustment panel did not work. This is fixed.
• MaterialEditor: When a texture is in the Environment slot of a Basic Material, the texture is assumed to have emap mapping.  The controls that previously appeared on the texture for mapping (Local Mapping) didn't do anything - so they have been omitted.
  
• Toolbar: Several problems using the icon editor have been fixed.
• Untrim: The RemoveEdge option to replace the edges with a curve failed. This is fixed.
• Worksession: The color of objects selected in a worksession file was not correct. This is fixed.

• SelBoundary: A previously selected curve can now be selected as a boundary.
• WireCut: A new Line option has been added.
  
  • If one curve is preselected, prompts for objects to cut.
  • If a surface or polysurface is selected, prompts for a curve to cut with.
  • If one curve AND surfaces or polysurfaces are selected, no further selection is needed.
  • If more than one curve AND surfaces or polysurfaces are selected, prompts to select a curve to cut the surfaces or polysurfaces with.

• SplitFace: A line was sometimes left behind when the command completed. This is fixed.

• Dimensions and Text that are made in model viewports scale differently in layout viewports.
  
  • Text is now affected by Document Properties > Text > Model space text scale.
  • Dimensions are affected by Document Properties > Dimensions (style) Model space scale setting.
  Note: Until the templates are updated, you need to run the TestAnnotationScaling command to turn this feature on in new files. The TestAnnotationScaling command turns the scaling on and off for both text and dimensions.
   
  Text:
  A new Document Properties Text page contains Model space text scale setting that multiplies the text Height in standard model viewports.
   
  When a new file is created, annotation scaling will be on and when an old file is read, it will be off. Since the settings are file properties, they depend on the template file used to determine if it is on or off in new files. Templates are not yet updated to have it turned on.
   
  It is important to adjust the height of the text after turning on Annotation Scaling.
   
  For example, if the text height is set to 1, it will be 1" in a layout. Adjust the text height to 1/8" or 1/4" or whatever plotted text height you want.
   
  Layout scaling is a new per-object property for text. 
  The Create Text and Properties dialog box have new checkboxes to turn Layout scaling on and off.
   
  Layout scaling is on and Annotation scaling is on:
  
  • In model viewports: The text Height value multiplied by the global Model space text scale value determines the text size.
  • In a detail: The text size is determined by the text Height value multiplied by the zoom factor of the detail. Text appears on the paper at the basic text size.
  • In layout viewport, not in a detail: Text appears on the paper at the basic text size.
  Layout scaling is off or Annotation scaling is off:
  
  • No change - Text Height is controlled only by the Height property of individual text.
  Dimensions
  Set the Scale in the Dimension Style dialog box.
   
  Dimensions:
  Annotation Scaling on:
  In model viewports:
  
  • No change - the size is determined by the dimension style Layout sizes values multiplied by the dimension style Model space scale value.
  In a Detail (layout viewports or model viewports):
  
  • The dimension size is determined by the dimension style Layout sizes values multiplied by the zoom factor of the detail.
  • Dimensions appear at dimension style Layout sizes values in layout space units - 1/8" high text is 1/8" high on the paper.
  In Layout viewports (not in a detail):
  
  • Only the dimension style Layout sizes values determine what you see - 1/8" high text is 1/8" high on the paper.
  Dimensions: Annotative Scaling  off:
  
  • No change - The the dimension style Sizes value multiplied by the dimension style Scale value applies in both model and layout viewports.
  Notes:
  
  • In Perspective views in details, the target point is significant in setting the text size for annotation scaling.  The target point should probably be on the plane of the annotations.
  • You can turn Layout scaling on and off per object for text but not for dimensions.
• SelectionFilter: The first attempt to make the subobject prepick pay attention to SelectionFilter is now in. Right now it only affects polysurface face and edge picking. The edges are essentially curves, and polysurface faces are surfaces. So, if you unselect "Curves", edges won't select when you Control+Shift+click. If you unselect "Surfaces", polysurface faces won't select.

• Radius: Reverted to V4 behavior allowing pre-picked curves. New selection options provide more choices.
• Save:VRML: Textures from VRML were being added with mode set to modulate_texture instead of decal_texture which blended the diffuse material color with the texture.  Now textures are added as decal_texture.
• Save: Reading and writing files larger than 4 GB is now supported.  This required a change in the file format. The latest Rhino 5.0 WIP will read any files. Using the SaveAs command, you can save files for V2, V3 or V4. If you save a V5 file that supports larger files and try to read it in an older Rhino V5 WIP, the older Rhino V5 WIP will tell you the file was written by a newer version of Rhino.  The fix is to download the newest V5 WIP.
