How do I get the vertices at the corners of a planar face?
Aaron_Hoover

I'm creating a FeatureScript that generates a half lap joint between two rectangular solids that are overlapped. (One half of the joint is shown below.)
I'd like to be able to generate a sketch on the plane that results from the Boolean (the "check" of the half lap) and position the sketch with respect to the resulting geometry. I'm able to get that face using qCreatedBy, qOwnedByBody, and qLargest on the Boolean tool I used to generate the geometry.
After that, I thought I could pass the query for the face to qOwnedByBody and specify EntityType.VERTEX to get the vertices, but that query resolves to nothing. Are vertices (and edges, for that matter) not owned by faces? If not, what is the proper way to query for the vertex positions for just this face?

for verteces of the face of the body you can use qVertexAdjacent(face, EntityType.VERTEX)

@Aaron_Hoover did you take a look at my lap joint? https://cad.onshape.com/documents/578ce95de4b0e425c1f00cda/w/cbc0b1ab48f411a4675afae1/e/6dbd408b8dc213a84767ec69Senior Director, Technical Services, EMEA0

@NeilCooke No, I hadn't seen your lap (I'm still trying to figure out how to find all the best/most relevant FeatureScripts to refer to for my project). It looks like this one will be super helpful. The base of many of the digital frame joints is a lap (and then some added extruded/Boolean'ed geometry). Thanks!
EDIT: I just checked out your lap. I use basically the exact same logic (Boolean intersection, split, subtraction, etc.) just without as much checking for special cases. Good to know I'm on the right track.0 -
