Hi Everyone

I'm engineer working in CATIA V5. A part of my projects are cuted on CNC machines (wood or metal).

In that case I need to export some shapes to DXF format, and I need to open it in AutoCAD and convert to closed polyline
for CNC machine program.

The problem appears when there are some arcs, rounded corners ets.

In DXF the end points of each arc are disconnected from the neighboring lines. The distance is very, very small, like 0,00000105mm!

I lost a lot of time for manually connect these breaks to achieve shape ready to convert to closed polyline (I using _pedit command).

Can anyone knows how to improve this work?

I have checked options in CATIA. Each time with the same result.

Maybe there's some option in AutoCAD for ignoring such small distances?
