Pros

The ability to work with multiple native CAD formats directly is impressive. I really appreciate how flexible this tool is for different workflows.

Cons

The lack of parametric features is frustrating and there's no change history when you're modeling, makes it hard to track what you've modified.

Pros

It's not user friendly and once you get the hang of it, everything flows smoothly. The drafting process does an excellent job getting detailed specs down to the fabricators on the shop floor. We rely on it for creating tooling for sheet metal stampings and after mastering the basics, making changes becomes incredibly simple which is a lifesaver in the prototype business where adjustments are constant.

Cons

The sheet metal unfolding feature struggles with blanking parts that have beads and it can't handle parts with contours like some other software can.

Pros

I really like how interactive the interface is and it's surprisingly quick to pick up because most CAD tasks can be done with just four main operations, pull, move, fill and boolean. What would take forever in other CAD software is simple here. The geometry repair tools like stitching and fixing missing faces are huge lifesavers when working with complex models. That CTRL+scroll function for selecting background faces is genius. Share-topology and named selections work smoothly too. The scripting features are really powerful, although the documentation could use some improvement.

Cons

It doesn't always function properly, requiring significant manual work on parts when it fails. The interference detection feature can't resolve all part conflicts which means spending considerable time fixing issues manually. That default 'merge' setting for pull and move operations is really frustrating and you have to change it to 'no merge' every single time you do a fresh install. While the learning curve is manageable, it limits how much you can actually simplify complex 3D CAD components for production use. There's basically no documentation available for scripting functionality. You also can't create relationships between parameters which is pretty limiting.
