Thanks everyone for your response, I continue to experiment and learn. Once I switched to Foxfire I can see the debug results.

Thanks

I’ve become frustrated. I think JSCad may be to advanced an application for the average computer user. Here is a snippet:

const { polygon} = require('@jscad/modeling').primitives
const { extrudeRectangular, extrudeLinear, extrudeRotate } = require('@jscad/modeling').extrusions
const { offset,expand } = require('@jscad/modeling').expansions

let x =[[0,0],[-30,0],[-30,100],[40,100],[40,70],[0,70],[0,0]];

const v1 = polygon({ points: x})
const b1 = extrudeRectangular({height: .1 , size: 3}, v1)

const v2 = expand({ delta: -3, corners: 'edge', segments: 8 }, v1) // api indicates v2 should be another polygon
const b2 = extrudeRectangular({height: .1 , size: 3}, v2)

const main = () => {
//return v1 //ok
//return b1 //ok
//return v2 // looks ok, but I don't know how to examine the points
return b2 //breaks

}

module.exports = { main }

I installed JScad-now on Windows 10 and got about 4 warnings I do not understand. I can’t get it to work.

I use notepad++ and chrome, is there a better environment? How should an average user approach debugging? I didn’t see a console.log(polygon.toPoints()).

What I originally wanted to do is extrudeLinear a closed path with arcs and generate shapes to .round the base and top. The exstudefromslices examples are little to advanced.

Thanks,
