When it comes to modelling a product using multiple parts, CATIA becomes tedious. One need someone to sit with and learn with the experience from a frequent user. If switching from any other software to CATIA, it can be intimidating as learning curve is lengthy. For example, when working with complex shape in a knuckle joint, more steps are needed in part modelling. This cause part modelling lengthier and consume time more time, in comparison to SOLIDWORKS. However, CATIA is tremendously helpful in generating really complex features. Surface modelling is way easier when one know how to use it. It becomes really handy to make changes to the design later as well. The design history tree is also very well organized, which save time in later modifications
I see FreeCad as the perfect solution for a startup with limited resources that want to save as much as possible and doesn't mind using non-standard 3D CAD software, i.e., it's not required by customers to use specific software for compatibility. It's perfect for hobbyist use and makers who don't care about brands and pay monthly fees. I see it as very well suited for small businesses that need FEA (finite element analysis) and can't/don't want to pay huge amounts of money for it, just like us. I see FreeCad as less appropriate for big corporations or well-established businesses that need standardized solutions, compatibility with clients or good version management. Don't get me wrong, it can get the job done, but it will be much slower than state-of-the-art CAD systems.
The software is pretty heavy, even with computers designed for heavy-duty loads, resulting in long wait times to load files and make changes, reducing productivity.
Usability is awkward. Perhaps if you learn it as your first CAD, it will feel OK. Still, it comes from commercial CAD products like mine (Onshape, Solid Works, Inventor, Solid Edge). You will feel it is less intuitive, with a less polished UI, difficult to customize and, this is a subjective one, less serious. I'd love to see it improve the usability and UI. I believe the engine behind it is powerful, but how you interact with the software is still lacking.
We got frequent updates on CATIA. There are lots of update notes. Also, there are lots of lots of videos online to solve the issues that you can stumble upon. It also has a built-in help manual, which helps occasionally. I have gotten my education through a physical class on CATIA, so there are opportunities like that as well.
You can create solid or 3D figures more easily and efficiently using Catia than in other programs or in specific AutoCAD. You can also create different pieces to later assemble them and thus create figures even more complex or in greater detail. In the same way, you can make 2D drawings without much complication.
Freecad is used often when receiving files from multiple sources and the need to work with cad in various forms from meshes to solid cad. Often when receiving scans of 3d objects the format is easy to work with and convert to traditional cad later on. There is no other cad that can bridge the gap between all the cad formats that we found yet.
