Plane at an angle relative to object's face

cooperAL5P5 — Thu, 06 May 2021 02:25:32 GMT

I'm trying to create a plane that is perpendicular to a face on an object (crossing through one of the edges of that object). I'd like for this plane to stay perpendicular to that face even if I change the tilt of the object in question earlier in the timeline. Is this possible?

I can make that happen here, easy enough

but you have not shown your model, (which face?)

Might help....

As a matter of fact, I made a silly mistake, and I just figured it out. (Sorry I didn't share the model, was a little bit sensitive to putting the model up publicly).

I had jointed my object to one of the origin axes, and it seems that made the resulting Plane at an Angle I made on that object's edge follow the base coordinate system rather than the object itself.

Fixed by using a Rotate feature via the Move command and capturing the position, rather than jointing to the origin. Now the Plane at an Angle follows the object's tilt movements.

Sorry about the false alarm there. Thanks!

I was wrong about the solution I thought I found, too actually, it's still not working.

This is a good workaround though, thanks for the tip! Plane along a path works pretty well, given there is a path that is going in the direction I need, and in this case there is. Unfortunately this solution means I have to crate a plane along the path of a fillet's edge in my model, which isn't totally ideal since fillets seem to be slightly more volatile than regular edges, but so far it's not breaking even if I change the fillet size.

I still can't figure out why my Plane at an Angle attempt is always at an angle relative to the base coordinates though. The plane itself is in a component that is tilting, albeit earlier in the timeline, but I feel like that plane should be tilting with it, not maintaining 0º relative to the project's origin planes.

Dave suggested an offset plane on another object that is already in the orientation I need, so that works as a workaround too.

After much help from dave and also guenther's Plane on a Path solution, here's what I've found out in a nutshell:

For a plane to always stay perpendicular to a face, Plane Along Path really is the best solution.
Plane at Angle's "angle" parameter will always be relative to the origin axes/planes of the component of the edge you select as the reference. If the angled plane doesn't update with parameter changes, it means the way that the object in question is being updated isn't actually rotating that object's/component's origin axes relative to the Document origin axes.
