how to select the parting line for plastic snaps.

Hi,

I have a plastic enclosure of two parts as top & bottom.

Both should met with dual snap joints. So I made a design for snaps. See the jpeg attached.

Now I applied the draft from mating surface of a part, that is my parting line.

But I dont know is there any parting line requires on snap area also.

Should I need to have a parting line at snap area??
