HEEEELP! How to edit an .igs file on PTC Creo?
Hello,
I am using PTC Creo Parametric 2.0 and I really need to edit an .igs file!
I can import it and open it but i cannot modify the geometry or like modify the original sketch...I am just able to move the parts.
What I need to do is to create another sketch over the geometry and the 3D I import, cause I need to draw and add another "piece" to it.
If anyone knows how to do it please reply! 
Thanks in advance
