Thanks for the replies.

All I really need to do is have the Jscad viewer display my file (which may be an STL or a JSCAD file) when the page loads. Is there any way for my javascript code to make the view display my file?

I'm trying to use Jscad to display my 3D models. I have code which I got from openjscad.xyz to create the viewer like so:

const el1 = document.getElementById('jscad')
const jscadInst1 = jscadWeb(el1, {name: 'jscad1'})

But now, how do I interact with the viewer? I need to be able to:

• load a file (STL or Jscad),
• set the foreground and background colors,
• remove any loaded files from the viewer

Any help would be much appreciated!
