OpenJSCAD.org [Feature proposal] Rendering multiple objects

I have a little feature proposal: A lot of designs I make in OpenSCAD consist of multiple parts. Especially if I want to 3D-print in multiple colors. It would be great to have a OpenJsCad like feature (returning multiple objects) for exporting multiple parts in OpenJSCad! Maybe to even have the ability to download a .zip file (found this: https://stuk.github.io/jszip/) containign all the stl files. Sadly I can't program javascript. If I have spare time I might give it a go though.

Thanks. I added such a feature but it wasn't accepted. I'll try again.

What I do to render from scripts with multiple parts is adding a parameter to choose the part, then I make a batch file where I invoke openjscad for each part (just changing the parameter and output file) and gather the result into a file.

pretty much everything already returns an array, so it would make sense to support it as output as well

These are the external formats that can convert multiple geometries into multiple objects (external format).

AMF
DXF
JSON
SVG
X3D

The only format that does not support multiple geometries is STL, which makes sense. STL by definition is just a raw, unstructured triangulated surface.

@Ph1r3ph0x Is this a specific feature for STL exports?

I once had a discussion about color printing with Mr. Prusa. He mentioned the above formats, but preferred 3MF for multi-color prints. The Prusa slicer handles 3MF files very nicely.

@Ph1r3ph0x please respond, otherwise this issue will be closed. Of course, you can reopen anytime.
