It seems that one 90 degree arc in Pro/E is split into 20 or more smaller arcs when I export to DWG. I work on large engine assemblies with hundreds of parts, and the exported drawing files have so many entities AutoCAD crashes. These are NOT complex curves, most are simple circles and arcs, yet they are subdivided when converted. Is there a setting that controls how fine Pro/E subdivides when it exports? Thanks.
