Following up on this, I tried ViaCAD's Edit > Simplify Object and it does allow some of the circles and arcs to be dimensionable.
The "WriteAnalyticCurves=y" idea sounded interesting, but for IGES and STEP formats. With moujiik's comments about setting resolution and the use of the "Arcs From Curves" tool, and that he uses the IGES and STEP formats, I've got the following recipe that is getting me closer to producing dimensioned drawings:
MoI:
[NURBS Export]
WriteAnalyticCurves=y
Select All, Export as IGES
ViaCAD:
Preferences > Custom Resolution > Resolution: Super Fine
New 3D file
Import IGES export file
Type IGES
Flavor: Generic
Trim Curve Options: Follow File
Auto Heal Bodies checked (have not experimented with turning this off and on)
Select all
Model To Sheet
Method: PolyLines
Use Draw Views checked
One Part Per Sheet checked
Window > Concept Explorer > Layers
Label sheets
Now at least the data is coming through from the MoI model & I can get some basic dimensions onto a construction drawing which is a big step forward. Thanks for the help!!!!
