igs flat pattern to .dxf format
igs flat pattern to .dxf format
(OP)
I'm searching for a procedure in Catia v5 to output a .dxf file from a .igs. Basically the .igs is a flat pattern laser template that I need to save as .dxf so i can process it through a laser programming software. Any help or advice would be greatly appreciated.

Rename the .igs to .ig2 -- this will load it into drafting. Now you can use Save As - .dxf.

I feel your pain. Must you use .dxf for your laser or could you use lines,arcs, splines from 3D projected flat on a plane? I do this for a water jet source.
Sometimes the gap will exist in the 3D solid. There is a merging tolerance in the Generative Shape Design (GSD) module, be default up to .0039". The merging tolerance is forgiveness but it will not correct the gap and will be noticed after file translations and/or disassembly. Can you get the native Catia drawing file?

The software I use prefers .dxf format. I can get the native Catia drawing file but in the past it hasn't helped much. In the past I have "fixed" the gaps between lines and arcs with my programming software but this can be time consuming be cause of the nature and amount of templates I process. I have had a bit of sucess with a different procedure using your tip of changing the name of the .igs file. I directed the designer to create the 3d wireframe and simply write it out as a .igs, then change the extension and re-read it back in to catia and save as a .dxf. This had the effect of eliminating the gaps and non-tangent lines and arcs (at least on the 1st 2 test pieces) I'm hopeful this procedure will smooth out the problems I've had with the models.
Thanks again for your inciteful comments and tips
