draft angle in mold design

Hello all,
I just want to ask a basic question. How dose NX define whether a face is positive or negative draft when doing the draft analysis or in the check regions( molded part validation)command? Can we say that if the face is invisible when see from the die draw direction, it is negative draft. Otherwise, it is positive draft.
Thank you.

Hi ,

I have not used mold design but i guess in fundamental terms your assumption is majorly correct (viewing the part from die direction.) .

It compares the angle between the surface normal and the draw direction you have specified and decides the positive and negetive draft regions.

You can test it using the isocline curves for a rough check on parting line.
