Onshape vs Zbrush: Which is best for you?

It is a "No worries" CAD system that allows you to focus on designing and not worrying about crashes, designs not saved, taking a wrong turn in a design and having to start over from scratch.

The versions when using components from different assemblies is a bit confusing, especially when created a standard parts library, then having to create a new version (V1, V2, V3 etc) when using on another assemby....

Even though it is intricate, there are SO many tutorials from the application itself to teach you anything you need - I especially love the custom user-interface, super accessible and helpful.

the learning curve is very steep. But also the fact that it is not possible to do rigging or animation on Z-Brush can make it less effective overall than other 3D modeling software that is efficient in all its other areas.
