  • RE: how to compile a JsCad script from string instead of file?

    @hrgdavor nice reply.

    that was my first thought after looking at the example from @Robert-Olson

    transforms (translation, rotation, scale, center, etc) are very fast, as only the matrix part of the geometry is modified. so, create a 'part' once and translate many times.

    here's a example from one of my designs.

    const makeRow = (h, p) => {
        let i = 0
        let x = 0
        let y = 0
        let c = circle({radius: p.case_b_v_h, segments: p.segments})
        let holes = [c]
        for (i = 1; i < h; i++) {
            y = y + (p.case_b_v_h * 2) + p.case_b_v_g
            holes.push(translate([x, y], c))
        return translate([0, -(y / 2)], holes)

  • RE: Could you share some book names to learn modeling with math?

    @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.

  • RE: I made a site for sharing my Jscad designs. Please tell me how you think about it

    @Cid-Zhang Fun site! Thanks for the inspiration!

  • RE: V2 Update 2021 Jan 02

    @gilboonet Thanks for the nice comments on the release.

    Any feedback on the editor is welcome. The editor is based on CodeMirror which has a huge number of options, themes, etc.

  • RE: converting .scad to .stl

    @Charlie-Funk Welcome!

    The best option is to use OpenSCAD application.

    JSCAD V1 ( 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.

  • V2 Update 2021 Jan 02

    Please get the latest version of JSCAD V2, as there have been some changes as well as bug fixes.

    New Features:
    web: initial implementation of the built-in editor

    Bug Fixes:
    modeling: corrected calculation of plane for complex slices
    modeling: re-implemented poly2.isPointInside to correct issues in expand/offset
    web: fix instant update
    web: corrected shortcuts for reloading scripts
    core: corrected logic of applyParameterDefinitions to retain parameter values when no definition is found

    BIG NOTE: The V2 website is also using this release.

    There's on-line documentation as well for those needing additional information about the modeling API.

    For those using a local copy of JSCAD V2, be sure to run the following commands.

    git pull
    npm run clean (and answer Y)
    npm run bootstrap

    Both CLI and WEB UI are usable for creating designs. In the WEB UI, it's best to drag-n-drop project folders to the window, and work with the pieces via a favorite editor. If "Enable auto reload" is checked then changes will be detected, and rendered again.

    For those wanting to get hold of JSCAD V2, it's still in 'early adoption' mode. But you can get started here.

    And a BIG THANKS for everyone that has provided feedback. Keep those comments coming!

    Have a great and safe 2021!!!

  • RE: Holes when using star primitive with extrusion and boolean operation

    @gilboonet thanks again.

    yeah. it looks like a t-junction issue again. if you have the time then please try the V2 branch called ' v2-fix-t-junctions', as some feedback on the changes would be good.

  • RE: Online versus offline functionality

    @drewpear strange indeed.

    sorry, but i don't have any suggestions at this time. i will post again if i think of something.

    by the way, i just submitted a pull request to enable the editor again for the V2 website. this should be available in the next 'alpha' release.

    i also opened a new issue for changing the shortcuts for the 'reload' of designs. this will be important for mobile devices which has soft keyboards.

  • RE: Online versus offline functionality

    @drewpear interesting.

    so, just to confirm things... you are running the application on Android OS... Chrome browser.

    Do you know the versions of Android OS and Chrome?

    I haven't seen this before so some more information would be useful to reproduce.

    You point about SHIFT-RETURN and F5 is valid. Mobile support should be available. Do you have any suggestions on a keystroke for mobile browsers?
