@ion-0 WOW! I don't do much wing designing (I used to build free-flights for fun though), and I've just begun to design in JSCad (moving from openJSCad), but I find this so amazing. There is so much I don't know yet, but I'd like to learn how to do a site like this. I assume you are hosting JSCad from your own server to allow this much flexibility. This is amazing stuff! Thanks for sharing!

Yes, this becomes quite limiting if one has to have users download, unzip, and drag & drop. Kind of defeats the purpose of projects. Also you'd have to deal with updates.
Very cumbersome for non-tech users.
It would be nice if you could include directories or even zip files in the URL.

Nope. Even renaming to index.js doesn't help.
It just doesn't like loading a directory from the URL line.
Drag and Drop works, but I can't load it by using # or ?URI=

I just get Error: fetch error: 500 Internal Server Error.
It doesn't seem to work with a directory.

I've created a directory containing a main.js file and a package.json that I can drag and drop onto the web site openjscad.xyz. It works fine.
I can drop just the .js file on the webpage and it works also, but not quite the way I want it to.
I can also run the webpage by passing in the .js file on the URL line, and while it works, the title on the page is a cryptic number. I seem to be unable to pass in just the directory as I can when I drag and drop. Is this possible?
How would I run with mutliple .js or .jscad files in one directory by passing them on the URL line?

Is this possible? If not, how can I get the name of the .js file to appear on the webpage instead of number that appears?

Thanks,
Steve
