Known Issues:

Limitations: Some trim edges might be distorted when importing certain Rhino parametric geometry.

Work Around 1: If you encounter such distortions, an optional Rhino 6 Plugin and Rhino 5 Plugin is provided to correct those distortions. Please download the plugins from the download section.
The plugin provides two commands
1, DS_Optimize: This would optimize the geometry in Rhino for transfer to Alias and other neutral formats.
2, DS_SplitKinkyEdges: This would split the edges at c1 discontinuities.

Work Around 2: Save the file in Rhino as v2. The resulting files will not have the distortions when imported to Alias
