[WIP] Sverchok, parametric nodes for architects

correct, for me at least it would be usefull mainly to read value to drive parameter in sverchok, but I could not resist to try to write data back…
An example for write mode could be a parametric part to make thread insert with some parameters to drive pitch ecc… I have to try it out

Btw, there is Spreadsheet node in Sverchok-Extra. You may find it usefull too.


There are more things in sverchock than are dreamt of in our…

Hello everyone!
this is my first “product” test of freecad-sverchok workflow.
Basically I made a simple box case design in freecad, entirely bound to a freecad spreadsheet, to better manage parametric data:

then I imported the design by freecad nodes and used a freecad sketch to generate in place the sverchok procedural geometry. It work nice, it’s a very basic design but I can say the workflow it’s quite promising:

so next step is to auto-generate drawings for wooden parts and STL files for 3dprinting!


QUESTION: are there already some batch STL export node in Sverchok?
I made up one on the fly using this library: https://pypi.org/project/numpy-stl/
I used export solid node like reference.
It works fine and fast…

the stl ouputs are correct, I’m going to print them out…

There is some STL support in Blender itself. Does separate implementation provide any features Blender lacks?

I didn’t dig into this, there is the bpy.ops.export_mesh.stl() function to export selected obj from the scene, but I wanted to make a batch export of a set of parts directly from sverchock.
Actually there is a write_stl() function in \scripts\addons\io_mesh_stl\stl_utils.py
I’ll see if I can use this one…

Hello everyone
I need help
How to align the plane to the average position of the mesh points?

this is a test scene
median-plane.blend (593.8 KB)
I need to get the transformation of this (or another) plane by points position of the mesh

There is linear approximation node in analyzers menu on bottom. Choose plane and use it as shown


You my hero!
