Full Version: Scripting the Trim command

Hi Michael,

Attached is simple open elliptical cone, and open cylinder.
BlendcapTest of edge of open elliptical cone, with closed edge, yields reading of 3 edges.
BlendcapTest of open cylinder with closed edge, yields reading of 4 edges.
There is no .htm file for this particular testing.

Maybe I'll go at it using the nametags assigned...

Hi Brian, thanks for posting the file.

So when doing this:

var trim_res = trim_factory.getCreatedObjects().item(0);

The 'trim_res' object is the full brep which for the cone will now have 3 edges - the original "seam edge" plus 2 edges from the closed edge that was trimmed. The cylinder started with 3 edges (2 closed edges at the ends and one seam edges), and when you trim one of those in half there will now be 4 edges.

Probably the thing that's got you tripped up is you were expecting to receive edges as the output, but when you trim an edge the output is a brep.

So yeah probably tagging the edge with a name before trimming it would be good so you could find the new edges when looking through all the brep's edges. The name should inherit into the trimmed pieces.

Thank you Michael, your response is logical, and makes sense :-)

(I just did a blend with a cylinder and a pentagon, and got 18 (brep) edges, with BlendCapTest, on the open circular edge)
