Solvespace is a CAD tool that makes heavy use of constrains and uses the traditional CAD way of building 3D models, where most of the work happens in 2D planes then gets "lifted" to 3D. It's useful when you build 3D objects that have to obey strict engineering constraints. 3D modeling for games / sfx / 3Ddesign rarely has such problem and typically follows a very different workflow.
