Certain files converted from DXF crash when the "arrows..." or "line styles..." dialogs are accessed. This is caused by information regarding arrows not being converted exactly correctly. The issue does not cause a distortion of the existing arrows in the file, but prevents arrows from being modified because the application unexpectedly quits when accessing arrows.
The way around this issue is:
1. Copy and paste the information to a new Claris CAD file. This can be cumbersome if the document has several layers.
2. Save the document as a MacDraw II 1.1 file. Then re-open the file and save it back into Claris CAD format. This is less cumbersome than option 1, but can cause issues for users with arcs.
The arcs may come back into Claris CAD slightly smaller than they were before. Please have users check for this issue if they choose to use option 2.
