Hi friends,
it took me a while, but the Voronoi on Solid node is now available. It generates a Voronoi diagram not on a mesh but on a real BRep solid and produces either clean solids or shells. It supports the modes solid voronoi cells (0), inverse solid voronoi cells (1), voronoi shells (2) and inverse voronoi shells (3), see figure. Enclosed you will also find a small demo file for an easy entry. Have fun with it!

Now you have my attention !

I am very interested in creating Voronoï type structures inside solids and was struggling to create a macro for it. I'm sure with that node I will be able to get the results I want much quicker.

Need to find the time to play with it but thank you for your work !

Hi friends,
just in time for Black Friday there are lots of new nodes. I have just published the nodes Extrude, Vector Math, Vector Length and Surface Center. Attached is a nice application example where Voronoi cells are extruded in the Z direction depending on their distance from the red marked point. Have fun with it :)

Models done with this WB are impressive!
As a simple user I hope to be skilled enought someday to use it.
Thanks for your efforts :D

After there is a reasonable roundstock of nodes and a stable framework, I will start a Youtube series to promote the Workbench and node-based modeling with FreeCAD. My intention is to pick up all users with small follow along videos. But it will take a bit more time i think :)

By the way, the node graph I have shown above is complete and does not need any further dependencies. That means, if you wire everything as shown, you will also get the displayed parametric extrusion. Just dare :)

That would be great :)

FC motto: it's done when it's done ;)

Just dare :)
You're right :D

Transform Nodes for FreeCAD Nodes
With the latest update the transform nodes Rotate, Translate and Uniform Scale are now available. All support multi input for all sockets and array broadcasting. Here you can see a simple demo for the Rotate node.

The new Align node allows you to align shapes to vectors. In the following example, I determine the surface normal of a sphere at selected points and align a prism to it. The duplication of the prism to each point of interest is done automatically by array broadcasting.
