I bought Alibre Design, as it was a less oppressive situation license-wise, but these days I find I’m using it less than I might supply because I prefer staying in Linux for literally anything else. It was a bit pricy, but at least it was a perpetual license. I am hearing that while they don’t intend to support Linux, they’re moving away from some of the libraries that have prevented Proton from working.

The rest are varying degrees of oppressive lock-in and feature erosion. PTC/OnShape in particular has a huge “Fuck-You” attitude towards anybody who wants to consider throwing a design up on Etsy or selling a few trinkets without paying out the ass for a professional-grade subscription, and being the only fully mature web-based tool, it’s the only one that works properly in Linux.
