There solution was “please send us the solidworks file”. So... I gave up.
More recently, I’ve been using Onshape. My understanding is that was designed by many of the Solidworks team. It works reasonably well and I’ve not had issues getting parts made.
Ideally I think I’d like something that was both cloud based and open source. But I should give freecad or Solvespace another chance perhaps.
Ack, that sounds rough--there can definitely be some pain on the bleeding edge (of open-source CAD.)
As far as cloud-based, do you just mean in terms of having that available as a storage/sharing option? Or are you wanting a browser-based client? I've been interested in looking at options for the former for FreeCAD, possibly using either Nextcloud or Mediagoblin servers as backend. (Unfortunately there doesn't seem to be a good FOSS product lifecycle management software.)
Emailed you the details in case it's of interest. Might need to check your spam folder as gmail sometimes puts things from my domain in there (mail config issue on our end, but can't be solved easily).
