Rhino 9 import&export routines displaying weird anomalies

I am seeing some strange and worrying behaviour when importing and exporting both SketchUp and AutoCAD files into and out of Rhino 9.

With AutoCAD I am seeing strange ‘gobbledygook’ text on import and weird flags for ‘missing fonts’ which were not in the original AutoCAD file (it reports ‘missing’ Helvetica whereas source document only used Arial) Importing the exact same file into Rhino 8 and it all behaves perfectly.

With Sketchup any meshes which have been ‘quad re-meshed’ or ‘shrink-wrapped’ in Rhino are a complete mess in Sketchup.. just weird fragments and disjointed surfaces when imported into Sketchup despite being closed and ‘good’ meshes in Rhino 9. With Rhino 8 I was exporting to render in SketchUp using VRay (company policy) but I’m no longer able to do that if i use Rhino 9

Given how quickly things change with WIP versions I suspect the Rhino developers would be better served if you provided the SystemOutput results and sample files that exhibit the problem behavior. Also mention the Sketchup and AutoCAD versions if that info isn’t present in the sample files. (I don’t use either myself so don’t know about that.)

yes, fair comment.. I am on deadline atm,.. will send when I get a chance.

Thought better to say something than not at Beta stage
