from the site you can download to the xpress version, with which you should be able to assemble up to 10 or 25 components (I'm not sure because maybe things have changed recently).
I tried it and it seemed good, it was based on sketches and driving quotas like all other normal parametrics.
modeling is simple, and also parameterization is very intuitive (i.e. the insertion of mathematical relationships between various sizes).
But I didn't put it seriously, I mean working on big assemblies, regenerating boards, or still trying to change references to axes and tables to see what happens.
