I've tried doing a search but can't find anything outside of basic extruding press E. Not sure what terms to use.

I'm trying to modify an existing model I have and finally got a block in here, but can't figure out how to extrude it to line up perfectly on these edges. It's my workaround cause I couldn't figure out how to turn this half triangle square into a square.

I'm used to SketchUp where I can extrude and it auto aligns to edges.

Ok I tried the snapping and none of the options do what I want. It's snapping to other things it touches. Here's a video (animated gif) of what I do in SketchUp. I'm trying to do the same thing. It's super simple in sketchup and I'm assuming it's super easy in Blender, but don't know how.

  • $\begingroup$ Added a new image to answer your question. I had somehow messed these squares and deleted some verticies and trying to re-build these back. $\endgroup$

    $\begingroup$ Easiest to delete it all except the bottom face, select that, and Extrude it up on the Z axis using the Snap to Vertex option to snap the height to the next one along. You can always add the edges to make the faces triangular afterwards if you need them. $\endgroup$

    $\begingroup$ Not had time to do a demo, but just as slight modification: With your face selected, hover over the reference corner then hit Z. Hold down Ctrl whcih should extrude the face to the same height as the reference then press Enter. Job done. $\endgroup$

Using a Plane and a reference Cube as an example. Go into Edit and Face selection mode, set the Snapping mode to Vertex on the dropdown.

enter image description here

Then hover the cursor over the corner of the reference cube, Hit E then hold down the ⎈ Ctrl key. That will extrude the face up to the same height as the cube.

enter image description here

Hit ⏎ Enter to complete the operation.
