I use camera-unproject to do coordinate mapping, but the obtained coordinates are obviously wrong.

code:

const regl = this.$el const handleMouseDown = (e) => { const x = 1 - (e.offsetX / regl.clientWidth) * 2 const y = (e.offsetY / regl.clientHeight) * 2 - 1 const point = vec3.fromValues(x, y, 0.5) const { projection, view, viewport } = this.camera const combinedProjView = mat4.multiply([], projection, view) const invProjView = mat4.invert([], combinedProjView) const result = unproject([], point, viewport, invProjView) console.log('convasSize: ', [regl.clientWidth, regl.clientHeight]) console.log('viewport: ', viewport) console.log('clickPoint: ', [x, y]) console.log('unproject result:', result) } this.$el.addEventListener('mousedown', handleMouseDown.bind(this))

Could it be that I did something wrong?

Ok, I have submitted an issue on github.

@jess-yan DXF is a old nasty file format so don’t expect much. JSCAD only converts certain DXF entities. Please see the README here…

There’s a nice library that will convert from DXF to SVG.

@z3dev @jess-yan yup. it is not implemented right now. But such feature has a lot more to consider to be implemented.

It may be beneficial to start a discussion on git to see what would be expectation of such functionality and what it would take to implement it.

@jess-yan another good question!

there's an issue with the internal logic of the WEB UI that prevents the 'script' to be shown. it's not that easy to fix either.

you can use the CLI (command line) application to convert the DXF file to a script.

you can find instructions on how to use the CLI in the README file at...

@jess-yan Super! Please let us know when a working website is available. There are many of us that want to extend JSCAD in various ways.
