Miter not behaving correctly

[fridtjofZM5ME]

Mitering a corner between a curved and a straight frame member used to work prior to the update. In fact I got it to work on one frame, but not on another. Why is that?

Hi! I don't believe mitering or most of the end treatment types support curve members. This is something Inventor should improve on. In the meantime, you will need to create the treatment manually by editing the member file itself.

Many thanks!

Hi,

In Inventor R 2019.2 there is possible to create miter between curved and straight frame. Your one profile seems to be not basic shapes, so it could be reason, but by default, it works. See please image where ARC + LINE populated by T-Shapes are mitered.

I can reproduce what you're illustrating here, where all the lines/curves are in the same plane. In my case the curve is perpendicular to the line (the curve is in a plane parallell to the top plane and the line is in the front plane), that also might be a reason for the problem. Although I got it all to work prior to the update.

Verified in Inventor R 2019.2 miter works in parallel planes as well - see video please.

Nice day

As illustrated, the problem is perpendicular curves not parallell ones.

OK,

 I see Trim in your situation can't create desired geometry, but Sweep feature (frame on curved is based on Sweep feature) has some functionality and can't do anything.  I want to say that miter works for 2 curves in 2 perpendicular planes in general, but there are situation where geometric solution isn't found. See please video showing miter works in general. Try to adjust your model/geometry to make miter working.
