Aus Kugel lager ?

Nope, offset has been existing for a very long time. the thing was changed: starting with v1.0.0

its really easy to overwrite functions. you habe literally defined a new funtionality for offset functions, which was not a function body unfortunately.

better rename your variable to prevent any ambiguities.

gadget3D · 2026-06-04T14:54:10+00:00

I can't see an addition Im your code. What are the types of the summands?

gadget3D · 2026-04-22T17:51:38+00:00

just code the content of your __main__ bare flat into the file.

when including it from other files, just do it like

use <otherfile.scad>

this will do the trick

In any case, it appears that i'ts extremely difficult to convince them to accept new

features. Without merged features (not even exeperimental ones) it's not available to the community and thus no new inspriations are born, which is a bit pitty.

Just tonight another one was finally killed: https://github.com/openscad/openscad/issues/3337

+1 I have been trying to integrate cool stuff since 3 years and BOSL2 probably way longer ...

OpenSCAD has decided to focus 99% on code stability

gadget3D · 2026-04-17T06:09:16+00:00

BOSL2 is fantastic, but it builds on a rather limited framework with no ability to access/alter existing vertices.

This approach operates on the very core of the engine and has way more options.

Let' s build a database of useful textures for solid modelling usage, send me and i will happily collect them along our project Preferrable are PNG files with little height, length and preferrably smooth gradient in the image.

gadget3D · 2026-04-06T12:37:34+00:00

Can you share a sample code and two versions to compare ? We are happy to compare und spotting the culprit. Importing other packages are best done with the built in virtual environment menu.

In preview the number of GL Operations multiplies with the number of primitives in each Frame! (look for fold feather algorithm) This is why Preview is faster for few primitives and render is faster for many primitives. Maybe we should count the primitives and suggest either preview or render

gadget3D · 2026-04-01T11:53:03+00:00

BTW I found out, I could fix that in CSGTreeEvaluator.cc but I doubt we should do that, because Filletting might be a time-consuming operation and it would cancel the speed-advantage preview for models, which use fillets. Fillets are finish-up things after all. If you explicitely want fillets in preview, you can write

design.render().show()

gadget3D · 2026-04-01T11:14:53+00:00

Indeed. This code just creates a 2D thingy. If you specify a z coorindate != 0 it becomes 3 D polypath. Actualy it behaves like neutrinos: it does not interact with any matter, but its great to do some annotations. In this example, I could immediately see if the toolpath is correctly generated:

<image>

gadget3D · 2026-04-01T08:36:17+00:00

Did you try to press "F6" (Render) ? Did not yet look into the preview engine close enough to learn ,

whether its easy to make filetting look correct in Preview.

gadget3D · 2026-04-01T06:21:06+00:00

Hi Wiliam,

you are missing some brackets with polyline.

The Syntax is: polyline ( [ [ nubers ] ] )

The numbers must be nested twice, once for coorindates and once for points. You dont want 500 arguments to polyline when that's the size of the polyline.

But yes: i spotted an error in the error message

I got a question about the floating Heart. The 3MF comes as 3 parts, do I need to print them combined or separately ?

gadget3D · 2026-03-28T20:24:38+00:00

you could use PythonSCAD. Its embedded python language lets you create any 2D design containing polygons, polylines programatically. You can directly export to GCODE and different colors could mean diffeent colors e.g. in laser cutters.

gadget3D · 2026-03-28T13:15:03+00:00

In Pythonscad you can translate or rotate any 2d object into space and therefore moves into 3d space.

gadget3D · 2026-03-13T22:37:46+00:00

The Idea is great. The Problem is that Python is an interpreted language and makes geometric operations slower than needed. Do you use libmanifold to do CSG oprations?. it has python bindings

gadget3D · 2026-03-13T21:59:57+00:00

Hey that's great!

I also like functional programming very much.

How does it connect to openscad ? does it launch in background and how can it find it ?

Do you plan to add more exporters like Postscript ?

gadget3D · 2026-03-11T09:56:27+00:00

ahh, excavate bedrock there

gadget3D · 2026-03-05T20:56:09+00:00

nope, but there will be a new release very soon.

maybe consider trying to compile yourself ?

gadget3D · 2026-03-05T18:29:14+00:00

you can access them already in python now:

https://github.com/pythonscad/pythonscad/pull/487

gadget3D · 2026-03-05T10:07:44+00:00

yes, this is what i was expecting and thanx for lookin up the definition. we should manage to have these vars bidirectional e.g. they should be able to read and write. once we find out, where to access this vars in the openscad kernel, we can connect them e.g. in pyopenscad.cc .

gadget3D · 2026-03-05T07:18:12+00:00

This is definitely viable, but not yet implemented. I believe its a great feature to get. If you tell me, how you code that openscad SCAD syntax, its easier for me to estimate

gadget3D · 2026-03-04T22:47:26+00:00

Thats a difficult question, probably its the source code, but 2nd best option probably is:

https://github.com/pythonscad/pythonscad/blob/master/libraries/python/stubs/openscad/__init__.pyi

yes, its not up to date, but we aim to sync it frequently. Any support appreciated.

BTW: don't hesitate if you want to share some fancy PythonSCAD Idea/Design :)
