How to upload a catia file correctly in GRABCAD
I upload a CATIA V5 assembly design in grabcad. When i viewed my model in the 3D mode inside the grabcad app i saw some sketches ( lines and polylines) which i used for designing the parts. But actually these sketches are hidden when viewed in catia software. Why this happen in grabcad app. What should i do to avoid this in future.
