How to make extrude solid not surfaces?

Lee_Hesketh · October 2016

Hi, what I need help with is I have performed an opExtrude() function and then used qCapEntity() to get the end face. I then have another opExtrude() to extrude the whole face another 3mm. However, the resulting geometry is a surface not a solid and I don't know why. Also if this wont work, how could I use the offset face feature like @NeilCooke's mortise and tenon script?

What I need is to extrude a user selected distance, which I have done, and then extrude again to perform a boolean subtraction, creating a mortise 3mm longer than the length of the tenon. Any ideas?

Thanks

A couple of things to keep in mind:
1. If you pass edges to opExtrude, you'll get a surface; if you pass faces, you'll get a solid. In this case, qCapEntity returns both edges and faces. You can do qEntityFilter(qCapEntity(...), EntityType.FACE) to get just the faces. (If you look at the debug output, it tells you that it resolved 4 edges, 1 face, and 4 vertices).
2. evaluateQuery returns an array of queries, not a query (and you can't usually pass an array of queries to an operation, like opOffsetFace, that expects one query) -- you can always pass the array to a qUnion to turn it into a single query, but in this case, it's better to just not evaluate the query in the first place (you probably tried that first and opOffsetFace probably failed because it was getting edges -- see point #1 above).

Hope this helps.
