Hi. I am completely beginner in Edgecam so sorry if question will looks stupid. I am trying to simulate milling in EdgeCam 2021. I import part but I have problem that program dont want to recognize feature. Simple description of part. It is round bar and on top I want to mill surface which is build as lofted cut where around during 8 section is changing angle. It is quite complicate surface to mill but program dont want to recognize feature. Part is done in Solidworks, tried to import part as different solid ( stp, prt, X_T file, ACIS ASCII file) but always same. Can someone advice where can be problem? I can add stock, fixture, machine but nothing helping to recognize surface to mill).
Hope I did explain my question enough, if no I can add more explanation
Thanks for help in advance.
