I have Alibre, and use it occasionally for 3D stuff, but it's a bit
buggy. If you don't apply constraints just right when aligning
parts, it will disassemble things at weird angles. "Undo" works, so
it's not fatal, but annoying.

To avoid that problem while constraining parts in an assembly, anchor
the 1st part (preferably a "central" part). To do that right click on
the part name in the Design Explorer and select "Anchor Part". You
may want to constrain that first part to the major planes or axes
before anchoring, but if you do, delete the constraints after
anchoring to avoid over-constraint errors..

Thanks! I'll give it a try.
