And for those that don't want to wait... here's the full URL, which adds a query parameter to the end of the website URL.

@danmarshall please try again. i updated the link to use the new website.

V2 JSCAD has been released today. All packages have been published to NPM, and are available for use in other projects or applications.

There is also a NEW website for JSCAD at www.openjscad.xyz

Thanks to everyone that contributed feedback, comments, issues, and new designs.

And a BIG BIG thanks to all supporters! Those contributions allowed the creation of the new website!

And of course, thanks to Nodebb for hosting this forum!

z3dev

it's a good idea but not really good for the general users, as this forum allows users to register via email, github, facebook, etc.

requiring everyone to create a github account is not very nice.

letting users know about the github discussions is good. hopefully, there will be more discussions.

by the way, some folks are also interested in a discord server for jscad.

@gilboonet sorry for the late reply. there was a change to the OBJ deserializer (import) to translate the 'material' name to an internal color specification. So, if the OBJ file has several groups (materials/colors) then result will have several colors.

@dburt welcome

Yes. You can make that example work. You might want to take a look at this project, which uses the JSCAD CLI (command line interface) for compiling the design and exporting SVG. Specifically, the 'localfont' project.

https://github.com/jscad-community/jscad-text

If you are going to work with other JavaScript libraries, especially those using async functions or promises then take a look at the 'googlefont' project.

@gilboonet here’s a suggestion...

How about using the ‘class’ element?

https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/class

z3dev

@gilboonet thanks for the information.

I’m not sure if ‘id’ is a good choice as by definition ‘id’ must be unique across the whole SVG document. This seems to be special for linking, etc.

https://developer.mozilla.org/en-US/docs/Web/SVG/Element/defs

Any other suggestions?

z3dev

@gilboonet once again. Very cool!

There was a request to add ‘names’ when exporting to external formats. So far, only DXF exports support the ‘name’ attribute on geometries.

https://github.com/jscad/OpenJSCAD.org/issues/558

This is definitely possibly for SVG paths as well. Do you know which SVG attribute to set?

z3dev

@veysel-özer thanks for the nice examples.

yeah. this is the behavior of V2. it's probably a BUG when contracting 2D geometries, as 2D geometry must have non-crossing outlines by definition.

a fix can be done in the next version. when that will happen is a big question as everything is on hold waiting for the websites to be restored.

if you have time then please create a new issue at GitHub.

z3dev

We are planning to release on April 1st.

The only thing missing is the websites.

z3dev

We have a really strong group of users now. I think others will reply with some examples.

z3dev

@retroglyph welcome!

Ah... converting 3D slices to 2D... there was a similar question in the Development Discussions. Please see “2D slice from extruded polygon after substraction”

If that doesn’t help then let us know. There are several ways to get the outline of slices.
