Hi, Art
Data Exchange Format "yea right" Everyone made there own Format of it, Go Figure !!
The Leadtool.exe isen't happy, Must be missing some req. files.
Graham's original dxf loads with ether a untitled file name or leaves the previously loaded file name and shows a profile, w\missing arc's.
After loading in bob-cad and saving a new dxf, Shows file name and a profile, w\missing arc's.
Saving B-Cad dxf, After Chaining or Rev. Surface Normal, Then it's fixed.
Thanks, Chip
Edit: Graham, Yes those would be nice
