Today I was doing some text endraving in mold inserts. I draw and position my text in Autocad 2002, then save as a dwg. and open in Bobcad 20.7 to get toolpath. I did several letters, all went well till I used an elipse to make an "0" like I wanted it. Saved it, opened it in Bobcad, elipse wasnt there. Tried twice, it wasnt there either time. I made due another way, but am wondering what I was missing, besides my elipse?

can you try breaking the elipse into tiny line segments. i have no experience with autocad, but with bobcad ive seen alot of problems discussed involving incompatibility between arcs and lines. give it a shot

erase42, good idea!
I tried somethings that seem to have worked, if someone else has experience doing it another way, please chime in.
First I changed the pellipse setting in autocad to 1. Bobdad would open the ellipse, but it was "warped". So back in autocad I used the divide command to divide the ellipse into 100 segments. It now opens in bobcad, looks right, but I havnt checked dimensional accuracy.

EXPLODE!

This function will help. It will break the ellipse down into simple entities. This is the best method for exporting splines in DXF to BobCAD.

when drawing ellipses in autocad change ellipse values ----pellipse then set to 1 , then redraw ellispse this should allow bobcad to reconize it.
