Rhino 4.0 SR4 Release Candidate 1 Available

Rhino 4.0 SR4 Release Candidate 1 (Jun-2-2008) is now available for download.

This is pre-release software. If you are not comfortable running pre-release software, please do not download this build.

This release candidate has been tested by our internal testing staff and is believed to be stable, reliable, and suitable for use in production. As with all release candidates, however, there may be problems that we didn't uncover in our own testing. We expect several thousand people to download and test this Service Release and report any problems they have.

When we are satisfied that there are no major problems with this release, we'll release the Service Release officially.

Please report any crashes you experience using the McNeel Error Reporting dialog box that will appear.

New in SR4 RC Jun-2-2008:

• Dozens of crashes fixes and stability improvements.
• SelMappingWidget: New command - Selects the texture mapping widget.
• Right-click context menus are now enabled by default so they can be discovered by users.
• Intersect: Several failure bugs have been fixed.
• Join: A problem joining the ends of an open arc to form a circle that caused the change in the radius to be greater than the model tolerance has been fixed.
• Join: A problem with joining chained edges has been fixed.
  Most recently-used commands: Command names were incorrectly being added to the MRU list. This is fixed.
• MoveUVN: Running another command that changes objects while the MoveUVN dialog box was open caused a crash. To fix this, MoveUVN will no longer allow object changes while another command is running.
• File Import: several fixes to reading DWG, DXF, and SolidWorks files.
• File Export: STEP and FBX export has been improved.
• Trim: Several failure bugs have been fixed.
• Trim: A problem with the interaction of curves near surface and closed curve seams has been fixed.
