Is there a mate to fix just one edge of a part to be in a specific plane?

Hello

Using mates, is it possible to fix just one edge of a part to be in the same plane as a surface of a second part?

Background
I am aware of how Planar Mates work, but they seem to require that you specify two planes rather than a plane + an edge.
I am still quite new to OnShape...

Thanks

If the edge is linear then a planar mate should do the trick. If not, you can try using the tangent mate between the edge in question and a planar face.

Sounds like a tangent mate is what you're looking for. Like so: https://cad.onshape.com/documents/fd2f05a40e2aaaa5117020a6/w/0e61c5dd60a1a15a03cf441f/e/61901e915fc3a48a59048a0b

@Evan_Reese always has great solutions !

Here’s another option

Here are a couple examples of how it can be done using the desktop version of Onshape

In these two cases, I’m not creating a mate connector first. But rather, In both cases here, I am going right to the planar tool and creating both mate connectors from within the tool

Sometimes the interface will give you different feedback while in the process of setting up this edge to be planar to the face

So that’s why I’m showing 2 GIFs here in this post
