@bitbybit WOW! Your project is very ambitious!

I’m definitely going to try the site for my next design. It should be a lot of fun trying a different front end, and extended functionality too.

What kind of designs do you expect others to create?

z3dev

@gilboonet I was playing with this today.

I finally understand what you want to do... If you have a number like '20', the code above generates two paths. One for '2' and one for '0'. And you want to put those together into a single path for '20'.

Sorry. JSCAD doesn't support grouping of shapes today.

Does Inkscape allow two paths to be grouped? It may be possible to support simple groups via special ids, etc.

z3dev

Hmm… I looked over this several times.

It looks like the design is exported to DXF. And then imported into Inkscape. Correct?

The numbers seem to be incomplete. For example, 18 looks like 1P.

Let’s work with a simple example. Can you create a few numbers, and export to DXF?

z3dev

@gilboonet cool!

OK. DXF… color mappings vary between applications. Inkscape is probably using a different mapping then JSCAD.

z3dev

@gilboonet thanks for the information.

These days, operating systems are large, and applications are bloated. The only solution is more memory, which is really cheap. It may take a while to find the correct dim cards but 16 or 32 gigs will improve performance hugely.

@sea-dh1 Good point!

Let’s see what can be done with the documentation.

z3dev

@sea-dh1 the short answer is because documentation takes time.

Are there specific pieces that you would like to reuse?

z3dev

@sea-dh1 @sea-dh1 if possible then please open a new issue at GitHub.

@Sea-DH1 Welcome!

Hmm… not much information. Can you attach the STL file?

You can rename the file to A.txt. That should allow the file to,be attached.

z3dev

@gilboonet thanks for the good information.

I’d like to have the JSON export from the final results. The JSON will allow some testing of the SVG Serializer, which may have an issue.

Can you attach the JSON to this thread? You may have to rename the file to *.txt

z3dev

@sea-dh1 welcome to the user group!

The modeling library creates 3D shapes into geom3 data structures. Of course, three.JS has a different data structure for ‘mesh’. So, all you have to do is… convert geom3 data to 3js data.

No. JSCAD doesn’t support this. Good luck!

z3dev

@neonsnowcat Please try the latest version via www.openjscad.xyz

Hopefully, those missing triangles have returned to earth.

@gilboonet Super cool! It's nice to know that V2 is working for your designs.

Please post any updates or new designs.

z3dev

@neonsnowcat @neonsnowcat thanks for the post.

Yes. There’s an issue with the faces when exporting due to some very close to parallel sides. Please see Issue #951

https://github.com/jscad/OpenJSCAD.org/issues/951

There’s a fix already tested and approved, but will take a few days to release.

z3dev

@Cid-Zhang WOW! Thanks for the super encouragement!

It’s really nice to see designs being created using JSCAD. This is one of the best examples.

I’m looking forward to your next design!

z3dev

You seem to be stuck in the old documentation.

Please see the new website at www.openjscad.xyz, and from the help there are links to the User Guide and the API documentation.

Hi @Ashish

Did you find some solutions?

The library doesn’t have a function to measure length, but this could be added. Paths have a set of ordered points so the length between points can be calculated. Not sure about 2D geometry but the length of the outlines should be possible.

May I ask what you will do with the length? There are other measurements for area and bounding box.

z3dev

There's a new release of JSCAD, including changes from several pull requests.

Features

core: remove VTREE from core and web modules
io: new serializer for OBJ
obj-serializer: new serializer for OBJ

Bug Fixes

obj-serializer: added default material when serializing objects without colors
modeling: corrected measureBoundingBox for mirrored shapes
modeling: handle negative area polygons in snapPolygons

Super Thanks to @platypii for the NEW OBJ serializer (export).
