@WolfgangFahl V2 Web is at https://jscad.xyz/

@WolfgangFahl Thanks for your comment! Since I'm not a professional web developer , my current goal is much smaller than yours, which is limited to exhibiting my designs on a static site. The version of the core jscad file remains the same and the file is reused over and over again. It would take a lot of effort when it comes to hosting a website which can receive and exhibit designs from multiple creators.

@z3dev I already tried to use a branch locally but didn't managed to make it work, so I stick to web version at https://jscad.xyz/

@crysislinux another very good area for some nice documentation. Currently, the 2D curves are based on Bezier curves. And the IO libraries convert various curve definitions into bezier curve definitions. SVG paths can define bezier curves as well. You'll find lots of online tutorials on how to create bezier curves. And hopefully, you will be able to apply some of those examples within JSCAD. P.S. 3D bezier curves are called NURBS.

@Charlie-Funk Welcome! The best option is to use OpenSCAD application. JSCAD V1 (www.openjscad.org) supports a subset of the OpenSCAD functionality, and you can just drag and drog the file onto the lower white space (It says "Drag and drop file here...") I hope that you have copy of the original .scad file. It's just a text file, so you can open and check the contents with various applications.
