Download Service Release 2 Now

New Features:
• Shade
  Shade is similar to the Rhino 2.0 Shade command - you can press any key, left-click, or right-click to return to the previous display.

  In addition, there are several command prompt options that let you quickly change the display to suit your needs. These options include:

  • Display mode (Shaded, Rendered, Ghosted, Flat shaded)
  • Draw curves
  • Draw surface wireframe
  • Draw grid
  • Draw grid axes
  • Background color of StaticView mode

• The -NamedCPlane command now has a Select option that lets you click the screen to select a named construction plane.
• Rhino now imports VRML files.
• TreeFrog Help has been added - please let us know if anything is missing.
• Camera Animation Tools have been added - these are just like the ones that came with Flamingo 1.0, but work with all renderers. The toolbar is linked under the Render button on the main toolbar.
• Romer/CimCore digitizing arms are now supported in Rhino 3.0.

Installation:

• When logged in as a user other than the one that installed Rhino some parts of Rhino were missing: toolbars, help files, and template files.

Stability:

• A crash when shading bad surfaces has been fixed.
• A bug in the Revolve command that made invalid surfaces is fixed. Shading these surfaces caused Rhino to crash.
• A crash with saving AutoCAD files has been fixed.
• A startup crash in Windows ME has been fixed.
• Adding Text to a file could cause a crash in some circumstances. This is fixed.
• An intermittent bug that caused Rhino to crash when opening some files has been fixed.
• An obscure crash with Make2D has been fixed.
• Canceling the render process quickly with Esc caused Rhino to lock up. This is fixed.
• Certain option combination for naming multiple objects with incremental numbers in scripts crashed Rhino.  Namely Increment=Yes and InsertZeros=No. This is fixed.
• Commands that were canceled with Esc could cause a crash when a new file was opened.
• Crash bug with Loft has been fixed.
• Deleting all command aliases caused a crash in Rhino. This is fixed.
• Editing very large toolbar buttons crashed Rhino. This is fixed.
• Empty dimension strings caused a lock-up when editing. This is fixed.
• InsertKnot could cause a crash in some cases. This is fixed.
• InterpCrvOnSrf on a cone could crash Rhino. This is fixed.
• Invalid surfaces cause OBJ export to crash. This is fixed.
• It is no longer possible to run commands from the keyboard or menus while an operation that takes a long time to run is in process.
• Make2D crashed frequently when cancelled with Esc. This is fixed.
• On Windows 98 systems, text in the Block Manager dialog box was either garbled or caused a crash.
• Pasting the text "Paste" crashed Rhino after a few rounds. This has been fixed.
• Running nestable commands, changing views, etc., while a long process and then canceling, caused Rhino to be prone to crashing.  Keyboard and mouse can no longer run commands or change views during long processes.
• Running the List command while surface analysis was in effect crashed Rhino. This is fixed.
• Several crash and failure bugs in STEP import have been fixed.
• SynchronizeViews could cause a crash in some situations. This is fixed.
• The ExtractControlPolygon crashed with spheres and ellipsoids. This is fixed.
• The Patch command crashed when it ran out of memory. This is fixed.
• The Taper command crashed when used on surface control points. This is fixed.
• Trying to Extend closed curves dynamically could crash Rhino. This is fixed.
• Typing CloseViewport and pressing Enter caused Rhino to crash. This is fixed.
• Using ProjectToCPlane on a block object, created an object that crashed Rhino when the file was opened. This is fixed. In addition, ProjectToCPlane no longer allows this.
• Using UnrollSrf on a polysurface crashed. This is fixed.
• Using the deformable option on the Revolve command caused a crash. This is fixed.
• You can no longer cut, copy, or paste geometry while another command is running. This was a potential cause of crashing.

Display:

• Dragging many objects caused the viewport regeneration to be very slow. This is fixed.
• ShadedViewport was slower than RenderedViewport. This is fixed.
• A bug that caused meshes to continually generate on bad objects with view changes has been fixed.
• Control point editing while in analysis modes (e.g., Zebra) could cause the surface to go black. This is fixed.
• Dragging mesh primitives with dimensions in the same shaded viewport, caused the mesh to unshade. This is fixed.
• Several changes to OpenGL Display were made. Rhino should now do a better job selecting the correct OpenGL display mode and objects should display with less artifacts.
• The Options OpenGL page, list box labeled "driver display modes" incorrectly allowed modifying the list names. This is fixed.
  
• The Pan, Zoom, and Rotate commands incorrectly refreshed the screen in a very slow but accurate way. This made Pan, Zoom, and Rotate using these commands much slower than using the associated right mouse button techniques. This is now fixed.
• The edge display in ShowEdges did not always draw the objects in the correct order. This is fixed.

OSnaps:

• Apparent intersections did not work in perspective views. This is fixed.
• Center object snap did not work on ellipses. This is fixed.

• A special case Quad object snap has been added for ellipses so it uses the ellipse's own quad points as well as the x and y maximum.
• Drawing a line tangent to a line at a point object or edit point on the line doesn't work. This is fixed.
• Entering x and y coordinates using feet and inches notation did not work properly. This is fixed.
• Many bugs in object snap precedence have been fixed.
• The Between object snap did not work for the second pick of a command. This is fixed.
• The Center object snap did not find centers of holes in surfaces. This is fixed.
• The Center osnap did not find the center of lines joined into a rectangle. This is fixed.
• The Intersection object snap took precedence on coincident curves/edges. This is fixed.
• The Midpoint object snap has been tuned up to find the midpoint of elliptical curves.
• The Osnap dialog box became garbled after resizing the Windows task bar. This is fixed.
• The Point object snap incorrectly did not snap to the vertices of mesh objects. This is fixed.
• The object snap priority was a hard-coded. This has been changed so the closest solution has precedence.
• There was no feedback tracking line with the Project object snap. This is fixed.
• Using point filters did not allow Ortho. This is fixed.
• Projecting object snaps were incorrectly used when in elevator mode. This is fixed.

• Several problems with toolbar locations changing have been fixed.
• Several bugs with the display of tooltips on the toolbar buttons have been fixed.
• Toolbar properties allowed renaming a toolbar the same name as an existing toolbar. This is fixed.
• The toolbar icon was not properly refreshing when Float to Top was used. This is fixed.

• Actions initiated by the Layer right-click context menu could not be undone. This is fixed.
• In the ChangeLayer dialog box if you typed a letter, the selection in the layer list incorrectly did not jump to the layer name starting with that letter. This is fixed.
• Pressing Enter incorrectly did not close the Document Properties dialog box Units page. This is fixed.

Download Rhino 3.0 Service Release 1 Now...

Bug Fixes:
• Several crash bugs fixed in MergeSrf, SetPt, and Scale have been fixed. These fixes may also fix other unreported crashes in Beta 15.
• Selection of objects inGhostedViewport is now better - you can select objects through ghosted surfaces by picking on wires.
• Fixed crash bugs in cancelling mechanism. This fix affects any command that printed "Press Esc. to Cancel" on the command prompt. Prior to this fix, the cancelling mechanism could corrupt memory, causing unrelated crashes in the future. This is now fixed.
