This should be a really simple thing in modeling, but for some reason the solution eludes me!

I'm modeling something simple made of 2x4 wood boards. I need to model a mitered cut. I can't just rotate the edge face because that would cause the board to narrow as it approaches the end, which is not realistic. I want to do something like an edge slide on the edge you can see here, slide it in the positive X direction (local) but I then want to be able to snap it to where it is directly above the bottom edge, but aligned on the global Z. enter image description here

If I actually try to use snapping it will snap back to where it currently is.

But this is what I need it to do, this is just eyeballing it, there must be a way to do this with precision?

    $\begingroup$ In your precise case, as the result is a vertical face, you could just use the knife, K to activate, C to cut through, A to cut vertically $\endgroup$ Commented Sep 6 at 7:18

One general technique that I've often found useful is to create a "guide" using either a separate object or by duplicating parts of the geometry and then use it as a snap target. In this case, you can select the bottom edge in edit mode:

enter image description here

Duplicate the edge (ShiftD), set snapping to Face, and do a Z-constrained grab to snap the duplicated edge to the top face:

enter image description here

Then, set snapping to Vertex and snap the rightmost edge to this "guide":

enter image description here

You can now select and delete the "guide".

(For this specific problem, you could also use the Knife tool with Angle Constraints or the Mesh > Knife Project tool with a plane.)

  • $\begingroup$ thanks for the pointers! I will try these out. I was really hoping there was some kind of snapping setting or feature that I wasn't aware of that could just do what I was attempting, seems I need to do things like this often enough. But at least this will allow for accurate modeling and not just guess work. thanks! $\endgroup$ Commented Sep 11 at 16:18
