Hello, you can do something like what I did on this post : https://openjscad.nodebb.com/topic/104/slicing-again-simplifying-code.

Hello, I'm testing my unflatting script on a Win 10 machine and it seems that there's a bug on this platform that tries to open an included file from the main script path, but it cannot work as this path contains the main script file name. It works fine on Ubuntu, so it can be something tricky to resolve.

To make it work for the moment I replaced the includes with their content on the main script, I can easily add this to my nodejs script that create a .jscad from the .obj file containing the 3d model to unflatten. Sadly, I will only be able to use this win 10 machine for a few days.

That's very good job, looks promising.

Thank you. I will try something similar, it just needs to add a parameter to choose a design number, if the table of random values doesn't have values for this number they are randomly feeded, else they are used for the rendering. Such "mechanism" could be handy for designs using both random values and more than one viewing mode.

Hello, I have a little programming design problem : I made a design that randomly builds a circular labyrinth. It has two modes, one to view the design in 3d as it would be when finished, and one in 2d with the background to lasercut. The idea is to first view 3d mode and update till the random arrangement looks good, then switch to 2d to save the pattern to .svg to cut it. My problem is that as the script uses Math.random(), when you switch from 3d to 2d, the design will change, is there a way to be able to use designs with random values that would not be lost when switching parameters (mode here) ?

The script is here : https://openjscad.org/#https://raw.githubusercontent.com/gilboonet/designs/master/laby_rond.jscad

Hello, I'm still working on slicing scripts, and as functions like projection and lieFlat won't be part of v2, I decided to write a simplier one. My idea was to get a 2d slice of a 3d volume by intersecting it with a volume having a flat top, then only keep the resulting polygons having all vertices with Z corresponding to the flat top Z coordinate. It seems to work fine. My aim is to teach basics of OpenJSCAD to non programmers crafters, so I'm looking for easy code.

The following snapshot shows a tiny jscad allowing to retrieve a cylindrical slice from a volume.

I'm using development web console to have output, that would be great to be able to have output parameters for that, but I understand that is not something critical, it can be handled using the console output.

@kaosat-dev At first I tried to use a 10K triangles model but as it didn't render I downscaled to 5K, 3K, 2K then 1K. And after, I made another model with 2x more slices that this script was unable to render even with a 1K model, so I changed the script to make it render chunks of slices, and it was ok. I suppose it could work with higher resolutions models.

Hello,
With the same script and 3d model, I made a 60 cm tall statue with 200 sheets.

finished

@z3dev I'm making the statue
