How To Remove Faces And Leftover Verticies

[jondhumphreys]

I'm writing a MEL script to automatically generate some geometry for a vehicle I'm modeling. As part of the script, I'm trimming the ends of some fins using a boolean difference command. As a result of the boolean command, the fin geometry gets automatically closed off at the place where the difference operation occurs, as seen here in the flat end that's facing the camera:

I need to be able to remove all of this geometry, so that the result is nice and clean like this:

Does anyone know of a way to remove not only the faces, but all of the extraneous vertices? I'm going to need to insert some edge loops later on, and if I don't get rid of any leftover vertices, they'll prevent me from creating continuous edge loops all the way around the fin.

Thanks for any suggestions.

hi! What about Delete Edge command? Its quite smart with that kind of stuff and will delete those Vertices!

Select the Faces > To Contained Edges > Delete Edge

Hi ewerybody. Thanks for your reply.

"To Contained Edges" is an awesome command. I had no idea that was possible, and it's exactly what I was looking for.

Unfortunately, when I attempt to use To Contained Edges > Delete Edge, a couple vertices get left behind. I have no idea why "Delete Edge" isn't removing them. Here's what "To Contained Edges" does:

And here's what "Delete Edge" does, leaving the two vertices that I've circled:

Any idea why these two vertices might be getting left behind, or how I might get rid of them using MEL?

Thanks again.

points are independent of edges. Just select all the vertices around and delete (maya wont delete vertices's that have more than 2 inbound connections unless you use delteVertex command.)

Any idea how I can select the correct vertices using MEL?

For the profile in the image it does not matter you can select them all.

the Delete Edge/Vertex command will delete edges and the verts

Edit Mesh > Delete Edge/Vertex

Yes that too. But basically just because it does the allmost exact same operation as the clearance you see here (it expands point selection to a edge selection and deletes the remaining edges true.). Points off to you, i was concentrating omnn his last step, which obviously one shouldnt do

whoever it can be too aggressive... so it is actually safer to select the edges first like thsi and then recall the selection around in veretx form and delete. Because if one of those grid lines happen to hit the underlying shape it might delete too much because it over expands. Now you can recall them by first convertting to edges not contained save that as a set then recall the face selection into contained edges then recall the set then convert to vertexxes and running conventional delete.
