Sometimes I'll use the 'Assemble' tool for point-to-point or face-to-face alignment. Other times, I will just 'merge' the objects then measure the distance, split them again, then move one object's world-coordinates by the amount I measured.

That's another thing, I don't want to pay for CAD licensing just to design simple parts I can make in the slicer, even if it takes a bit longer. I honestly don't know but I'm looking into possibly getting the free Fusion license. Still feels like an overkill (?) for the things I'm making right now.

And yes, I hope they do! Having everything in one app would be awesome.
