Export as FCStd #179

Closed samuk closed 1 year ago

samuk commented 2 years ago

Would it be possible to support export in FCStd format as well as the import?

We can do an export to brp. That is the OpenCASCADE internal format. FreeCAD opens those files with out any resistance. A FCStd file is just a zip file containing some XML and a collection of brp files.

Would brp export fit your use case or do you absolutely need FCStd output?

samuk commented 2 years ago

Yes it sounds like brp would do the job. Thanks

mmiscool commented 2 years ago

Ok. I think we can get this working relatively soon. Stay tuned for when this will drop.

samuk commented 1 year ago

Actually thinking about this, proper FCStd would be preferable. I'm thinking of future integration with Github/Gitlab where you could load your FCStd from a git URL and then save your changes to Git.

Does that seem at all viable/on your roadmap?

mmiscool commented 1 year ago

Import / export functionality relating directly to FCStd is really only for single direction data migration. It would not be especially good for active community design as each time a model is loaded or stored only the geometry is preserved. The part history would not be preserved going from one CAD application to another.

Is it possible to record the part history in a FCStd? I realise it's probably low-priority work. I do think frictionless compatibility with FreeCAD would aid adoption and resolve some use cases where FreeCAD currently has more functionality.

Put another way: If Jsketcher fulfils 90% of my design needs I'm likely to use it, and do finishing work in Freecad.

If I can't do finishing work in Freecad, then I'd probably have to use Freecad for the whold project from start to finish.

Well for now I pushed the "Export BREP" command. If you run from the dev branch you can give it a try.

samuk commented 1 year ago

Thanks, will have a go.

mmiscool commented 1 year ago

@samuk Was the export brep adequate for loading models produced in JSketcher to FreeCAD?

samuk commented 1 year ago

To be completely honest I found working with FLOSS cad tools so frustrating, I've just started working in ways that don't require 3D modeling. I'll try again in a couple of years, but the learning curve was too steep.

Closing issue for now.
