For professional CAD/CAM use cases? No. Those do not use meshes but more sophisticated and computationally expensive 3D modelling techniques. For hobby use? Sure. Most of that stuff uses meshes already.

Edit: it’s actually not just meshes that are supported. But the usual CAD/CAM surfaces are still not supported.

With a brief look at the example, it looks like they represent form with formulas instead of meshes, enabling fabrication from the form, for example. This is one of the reasons BIM software like Revit is so unhelpful for fabrication as they don't use formulas to represent the form so you can't get high enough accuracy.

Not sure what example you are referring to. I see meshes and some built-in geometries.

On closer inspection they do support subdivision surfaces! Just not the usual NURBs. So you could probably use this for professional modelling it just won’t be compatible with the industry standard software.
