I need some help creating a prting surface for a tool build. I have attached the model. I need to be able to extend the red surface out past the edges of the parts to create the parting surface.
I would look at the Ruled surface feature in SW. You could also do something with projecting edges onto offset planes and using extruded surfaces, if you want to simplify the shut off surfaces as much as possible.
But unless I'm not seeing something right, I don't think the red surface is necessarily at the PL, is it? It looks like the fillet around the edge has to be split in some places. I'm basing that on using the Front plane as the direction of pull. It's possible that the actual direction of pull is determined in some other way, such as perpendicular to the axis of the through holes. Yes, on looking at it that way, it makes more sense.
Anyway, the Ruled surface is usually the way to go.
Do you want to create a partline that is ruled around the edge perimeter or do you want to extend the interior surface? If the latter, that's going to be tough since the part was not model correctly and there is a degeneracy in two quadrants of the face (see attached) - faces like this are impossible to extend.
Best of luck.
Hi- Matt is correct, the part line does not follow the edge of the red face-
do a draft analysis - as per the pics attatched, and then go on to use ruled edges for generating th eparting surface
Thanks everyone for their help. I really appreciate it.
