Object opacity?

is there a way to lower a shapes opacity temporarily so that it would aid in aligning other objects behind or user other objects

You can set Opacity under Tools / Color. With the slider on on the right hand side.

is the opacity only with pro version?

The major update was released in December 2017, about 1 month ago (Shapr3D 3.0).

Saving Colors is a paid feature, yes. But you can try it out for free.
