What's New, WIP 2010-02-02 (2-Feb-2010)
(適合列印的版本)
修正項目:

• DimOrdinate: Did not automatically detect whether to make an X or Y datum dimension as it did in V4. This is fixed.
• MaterialEditor: A crash in the Blend material has been fixed.
• ReduceMesh crash fixed.
• Reparamaterize: When surfaces are included in a block object, they are duplicated for reparameterization.
• Text: A new Mask option has been added that displays a rectangle that hides the geometry underneath in the display and for printing. The mask color and border can be configured with TextProperties.
  

• Open:STEP: Now supports nonstandard schema names and abbreviated entity types created by Unigraphics.

• Autocomplete: The space between the exact and fuzzy matches incorrectly acted as Enter. This is fixed.
• OrientOnSrf crash fixed.
• RunScript crash fixed.

• Rhino Render:
  
  • The Content Browser is now gone, and you can replicate its functionality exactly with the new stuff.
  • There are default groupings set up for the tabs now.
  • The menu is now reconfigured.

• ExtractMeshEdges: A new Join results option has been added.
• Slab: New BothSides option added.

• Dim crash fixed.
• ExtrudeCrv crash fixed.
• FilletEdge指令：修正了幾項作業失敗的錯誤。
• Import指令：修正可能會當掉的錯誤。
• 開啟DWG/DXF檔案：修正當掉的錯誤。
• PatchSingleFace: The command incorrectly quit if a non-naked edge was selected. This is fixed.
• RemoveKnot: The display did not correctly update as knots were removed. This is fixed.
• Save:OBJ: Now supports long lines.

• Block: Blocks containing objects on layers that were turned off could incorrectly still be selected. This is fixed. Now, if you can't see the block (the layer the entities are on is off), when window selecting, SelAll, or SelBlockInstance does not select the block even though insert layer is still on, the instance is not selected.
  
• EditScript: Ctrl+Y now works as Redo.
• Merge2Faces crash fixed.
• Zoom, Target: The OnSrf object snap did not work with this command.

• BoxEdit: Can now accept units other than active unit system.
• Dimension Properties: A new button takes the user to the Style configuration page in the Options dialog box.
• Open: It is now possible to cancel opening files that are locked by another user.
• Purge: Optons now persist between Rhino sessions.
• Save:DWG/DXF: Schemes can now be imported and exported through the Edit Schemes dialog and the AcadSchemes command.

• BoxEdit: If you are in "Transform objects individually" mode, and if all objects have the same x, y, and/or z dimension, the corresponding edit fields did not show a delta. The same applies to the position fields. If objects share a pivot coordinate, then the position fields not longer display a delta. This is fixed.
   
  
• Contour: Some failure bugs have been fixed by new intersectors.
• CrvSeam: A failure bug has been fixed.
• DimRadius: Improvements in leader placement and editing.
• DimRadius: Now when moving a dimension point, the arrow leader attempts to stay level.
• DimRadius: The behavior of the arrow location has been improved.
• Extrude: The entire polysurface highlights rather than a face, and the extrusion is trimmed to the surfaces it first hits along its extrusion path.
  
• ExtrudeCrv: Additional checking for invalid extrusions has been added.
• Object Snap: The object drag osnap is now delayed by default. When you select an object to drag it, you now have 250ms to do an old style non-osnapped drag. If the osnap was able to snap to something, the cursor tail will disappear, and after the delay the osnap will be activated, and you can do a precise drag from the osnapped point.
• Open/Save: The open and save file location incorreclty returned to the default location if Rhino 5 is closed without opening a file or using the SetWorkingDirectory command. This is fixed.
• Open:DWG/DXF: In some cases, an unflagged bad object was created on import. This is fixed.

• Save:DWG/DXF: 
  
  • When exporting or saving to DWG/DXF, the "Primary text length factor" is incorrectly not being set in the "Default" imported style from Rhino. The AutoCAD control variable DIMLFAC is now set to match the corresponding length factor.
  • Special characters in layer names were lost. This is fixed.
  • Layer names with mixed upper and lower case were incorrectly converted to upper case. This is fixed.
• SelLast: A problem with selecting inappropriate objects has been fixed.
• VariableFilletEdge: Several failure bugs have been fixed.

• Blocks/Layers: Blocked objects on separate layers did not respond properly to layers being turned off. This is fixed.
• CrvSeam: Cancelling the CrvSeam command incorrectly resorted the layers in the Layer dialog box. This is fixed.
• FilletEdge: A problem with creating bad objects has been fixed.

• Untrim: Broken into 4 commands:
  
  • Untrim - Pick an edge to untrim a single edge or hole.
  • UntrimHoles - Pick a surface to untrim all holes.
  • UntrimBorder - Pick a surface to untrim outer boundary.
  • UntrimAll - Pick a surface to untrim all edges, holes, and outer boundary.

• Save:VRML: Texture color was incorrectly replaced by material color when the mesh objects are exported and imported with VRML format.  This is fixed.
  
• 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.
  

• RecordAnimation: A new option remembers a previously used target folder or allows it to be changed.
• ReduceMesh crash fixed.

• Dim: New arrowheads with longer 4:1 and 6:1 aspect ratios are now available.

• History: You can now edit the properties of a history locked object, like change the layer or color or use analysis commands that do not affect the geometry and therefore do not break the history.
• SketchUp Export now tries to make outer and inner boudaries out of planar mesh regions.  This makes the output more user friendly in SketchUp.  You can use the Push/Pull tool on whole walls now instead of single triangles.

• Crv2View crash fixed.
• DimOptions: The way that fractions and feet and inches were displayed in the dimension dialog box and on the sheet were different. This is fixed.

• 開啟PLY檔案：修正匯入PLY檔案時檔頭資訊識別不正確的問題。

• Open:STEP:

  • Import speed and memory usage has been improved. Opening a STEP file should be faster because of the new intersector code.
  • A problem opening large files has been fixed.
• 開啟STL檔案：現在可以使用STLImportOptions指令，設定匯入STL檔案時自動將網格頂點熔接的角度，預設值為22.5度，這項設定在Rhino重新啟動時會回復為預設值。
• 開啟VRML檔案：修正開啟PhotoModeler建立的VRML檔案的問題。
• 指令選項記憶：許多指令選項現在在Rhino關閉前會記住設定值。

• OSnap:

  • Tan: Sometimes incorrectly allowed a tangent to be located. This is fixed.
  • Quad: Did not override Perp in the case when the two are both valid. This is fixed
• 平移視圖：將判斷視圖是否正對工作平面的容許角度縮小，以滑鼠右鍵旋轉非正視的平行視圖時，比較不會因為視圖旋轉到接近正對工作平面的角度時，滑鼠右鍵拖曳從旋轉視圖變成平移視圖。
• PictureFrame指令：修正以OpenGL顯示時圖片顏色變淡的問題。
• 外掛程式管理員：如果Rhino啟動時載入某個外掛程式失敗或當掉，下次Rhino啟動時會詢問您是否要停用該外掛程式。
• Project指令：修正將多重直線投影至網格上的問題。
• Purge指令：修正會將圖層或物件使用的線型清除掉的錯誤。
• Pyramid/Cylinder/Cone指令：改善DirectionConstraint選項。
• Render指令：改善因為記憶體不足而當掉的情形。
• Options對話框：Render設定頁面 - 修正一個檔案的DPI設定會儲存至其它檔案的錯誤。
• Rotate指令：修正使用Copy選項時，儲存旋轉角度的問題。
• Rotate3D指令與Rectangle指令的3Point選項：修正在自訂工作平面的作業視窗使用正交時，使用的是世界座標軸向，而不是工作平面座標軸向的錯誤。
• RotateView指令：以滑鼠右鍵旋轉視圖時，按Alt+Tab切換到其它程式的視窗，放開滑鼠右鍵，再回到Rhino視窗時，不用按滑鼠右鍵就可以旋轉視圖的問題。
