Hello;
I need cad files *.igs or *.stp of the complete machine to do modifcation on the K8200 of my freind.
I use PTC ProE and i can’t do that with *.stl files.
Thanks for your answer an your help

I don’t know if this will help, but the DXF files are available on the 3DRAG wiki page:

reprap.org/wiki/3drag

reprap.org/mediawiki/images/2/2e/3DragParts.zip

Thanks but dxf files are only 2d.
For 3d we use step files ou iges files

I use Bricscad Platinium and DXF supports 3D

So I would find it very strange that Pro-engineer can not handle 3D DXF
Autocad supports also 3D DXF

DXF is text based so 2D or 3D coordinates is just a matter of 1 extra axis.
