Feature Request: 3D PDF Exporting to Asymptote format.

[jruiz]

There are many examples but I couldn't find one where a 3D mesh (with materials) will be created.

I hope the following could help:

• On p134 of Asymptote: the Vector GraphicsLanguage they describe what they call material.
• Also on p 89 of An Asymptote tutorial there is another brief explanation.

With git commit 4badaba52 you can export to an .asy file. At the moment this only works for meshes and you will find this function in the Mesh design wb under Meshes > Mesh export.

With git commit 50bbd522 and git commit 58a92681 it's now possible to also export colored meshes. They can be colored by face or by vertex.

Great!
Want to make some tests, but (forgive my ignorance please) I'm not sure about what to do now.
Does the entire FreeCAD source have to be downloaded, then four files in[git commit 4badaba52] be substituted and then compile the FreeCAD source?

Realized that you added the four modified files of the FreeCAD code in wwmayer Mesh: [skip ci] improve support of asymptote export .
Now going to download it from and compile it.
Any hint?

Yes. Werner modified C++ code, so you can only get the new functionality if you recompile the entire source code with these additions.

This is not a very complicated procedure if you know what you are doing. But if you don't want to compile, then you can wait a day for the Ubuntu daily package to be generated; or wait a week, for the new AppImage, Windows and MacOS packages to be generated. Then you can test the new functionality there.

Gonna try to compile it. Wanna see FreeCAD exporting to Asymptote.
If something fails I'll wait for the binary

I have to congratulate you. You made an excellent job in a very short time.
Now, as I see it, FreeCAD expanded its functionalities in the interchange of information.
I think it is a very good news.
Regards.
