Shapr3D Parametric Beta
shapr3d.comIt really has a great user interface compared to other more traditional 3d tools. For example if you want to bevel an edge you just start dragging it, if you drag it in one direction it will fillet and if you drag it in the other direction it will chamfer.
But on the other hand I'm really not a fan of their rent to own model. It only takes 1-2 years and you'd have spent as much as you'd have done buying some other apps.
