@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. https://stackoverflow.com/questions/5188561/signed-angle-between-two-3d-vectors-with-same-origin-within-the-same-plane

@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.

@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?

@shay-cerny Welcome This isn't exhaustive but lists some of the websites using JSCAD. https://openjscad.xyz/dokuwiki/doku.php?id=en:user_guide_help

An application also has shortfalls. There's the problem of documentation as well as upgrades. Applications usually include a huge and often critic user manual. And applications will only receive the latest patches if the user notices and applies the fix. This is why the website is so appealing... it's easy.

@Shunder0 i do not understand even slightest what you are asking here

@LucaNitti Welcome! There are a couple of ways to use DXF files. You can convert the DXF to another format, like SVG. Or you can import the DXF, and use the shapes to create different designs. You can convert using the JSCAD CLI command. If you want to use the shapes from the DXF file in designs then a project is required. https://openjscad.xyz/dokuwiki/doku.php?id=en:design_guide_projects

@hrgdavor Thanks: https://github.com/jscad/OpenJSCAD.org/issues/1317

@Jason-Sprouse hmm... The website doesn't have a backend service/process. Everything is handled by the browser, including loading designs. The only trick is for designs provided an a URL parameter. In this case, the URL is posted to a little script that reads the contents, stores the file locally, and returns the URL to the local file. Of course, some other backend service could be added.

@Hermann-SW said in Are there JSCAD user callbacks?: tionality? Wouldn't that also be displayed in the browser stack trace?

@Hermann-SW You are not alone! I had the same experience, back in March.

@z3dev got my first email from this user group and daily digest. That is great news that you got this working.

@Hermann-SW Good questions... The website has a little Perl script that does the download of the requested file, and checks the content. This does two things; only know file types are allowed, and this goes around CORS. https://github.com/jscad/OpenJSCAD.org/blob/master/packages/web/remote.pl I guess that supporting data URL would be possible, but there would have to be some similar checks for data type, etc.
