@sopatt Sorry to the late reply.

You probably already know this but an ''orientation" is required to determine the rotation, and sign of the angle.

This is probably the best implementation out there. And if you want then this could be added to the vec3 functions.

@Christopher-Fry OH! A V3 user! Awesome!

The modeling library is getting there, and pretty mulch complete, functional, and tested. We expect a few bugs, and a few more API improvements. But nothing radical.

Also. we are setting up a new website which will have a landing page, both V2 and V3 web UI applications, and more.

There's no plan yet for the BIG switch to V3. So, expect a few more V3 beta versions.

@BOYUAN-SHI Welcome

I have done some designs using my iPad, which was a little cramped for viewing. Technically, everything worked fine.

If you are working with a project with multiple files then probably a PC would be better. You can drag and drop the whole folder to the website. And change any file.

I think most people use a favorite editor to make changes, and drag and drop the file to the website. That works really well.

There's a new release of JSCAD V3 Alpha, including changes from several V2 pull requests.

NOTE: For CLI users, please see the new command line options.

Features

• modeling: added isConvex to geom3
• modeling: added minkowskiSum for 3D geometries

Performance Improvements

• modeling: changes to optimize removal of polygons in reTesselateCoplanarPolygons
• modeling: optimized creation of end caps in extrudeFromSlices
• modeling: optimized mat4 creation in extrudeRotate

SUPER BIG THANKS to @jbroll for the new Minkowski summation function.

@sopatt @sopatt That's cool stuff. In the early versions there was a 'connector' concept but that was left behind. We really want to bring that back in V3, so I'm wondering if your efforts could contribute to a better version.

@patilanz Welcome,

Sorry, I didn't see this before.

DXF web editor. DXF is just a file format created by Autocad long long ago. There are many online websites that can read as well as create DXF files, including JSCAD.

Does that help?
