I got a trouble with a EMCO lathe - 840D sl with S, X,Y,Z, C axis.
I used laser scanner to get the 3D model of the part then used NX10 to do the CAM and exported the part program (~140k lines of code)
The machine could run the part program no problem.
However when i ran the 3D simulation of the part program it couldnt simulate the C axis properly and gives me strange lines across the screen.
Can anyone enlighten me what the problem is and how to fix it?
I attached here also the exported part program.

Thank you very much for your help
