I work with huge engine asseblies (1000 ^ parts in an assembly) that must be exported to AutoCAD drawings for our customers. Sometimes the AutoCAD .dwg file has so many entities in it that AutoCAD can't open them. It seems that each curve in Pro/E is broken down into hundreds of smaller curves, which is driving up the total count. These are NOT complex curves, most are standard circular arcs. One 90 degree arc in Pro/E will become 25 smaller arcs when the conversioni is made. Is there a setting that can limit the amount of entities that Pro/E generates when it does the conversion? Thanks greatly for any help.
