mabat, Autodesk has just reduced the functionality of the free version of Fusion 360, the main sticking point being that step export is no longer allowed. This would make it hard to transfer between packages or give a file to a CNC shop. It certainly is a pain for what I have been using it for lately.

How hard would it be to get the curve import going on another CAD program?

Yeah, I've noticed that, a pity. I don't know, the best advice I can give you at the moment is to get everything done before 10/1

Probably some solution will emerge but right now I don't have a clue.

Can you explain how the curve import works in Fusion? That might help to work out how to do it with other programs.

First, it must be a free (or cheap) program, otherwise it makes a little sense. I'm not an experienced CAD user so I don't know much about the possibilities in this area. Scripting language (as with Fusion) would by nice but not really necesary I guess, as long as it is possible to create the shape manually. If you are interested how it's done in Fusion just see the import scripts - nothing more than the commands available are used there. Basically it imports the splines and then uses the loft feature.

FreeCAD can be scripted through Python as it is built to do that, it's not as user friendly as Fusion 360 but being open source the same feature limitations won't happen

This seems like it could work to create to create the curves from the points files if the data was changed to the right format?

Sure, I think you could try it right away - see the Output.Coords options.

Is there a way to set a space as the delimiter? I've tried a few options and got nothing useful. I can set it to something else and change it with a text editor if needed.
