I just posted this as a comment/response on another thread but figured this might be something that others could find useful. so here goes.
This short tutorial shows one way to create a compound angle cut on an edge of a 2×4. this can translate to any other situation where a compound angle is needed:
I started with a 2×4, used the protractor tool, and made a guideline from one corner at a 10 degree angle:
I then selected the opposite EDGE of the ‘board’ and using the MOVE tool, moved it down (select move tool, click on the edge, then press on the UP arrow key on the keyboard to lock the move to only the up-down (blue axis) direction) to the guideline:
I then created the compound angle on the other face of the 2×4, at 10 degrees:
And selected the adjacent EDGE to the one I moved earlier, and MOVED this new EDGE down to the NEW guideline:
Since this is a component, you can see the original 2×4 bounding box with the newly created compound ‘cut’ end:
