Can you create a shape with voronoi designing?

Sorry I did not know that you only wanted a 2D Voronoi pattern.
This is very easy to do but a bit time consuming.
Draw the basic shape that you want the voronoi pattern placed.
Make a New Layer.( In the 'Layer' tab right click 'New')
Using the 'Point' tool place Points in a random pattern.
Make a new Layer. Join these point to the nearest other points.
Make a new Layer. Draw short lines from the midpoints of lines already drawn.
Turn off with the 'lightbulb' the first Line layer. Extend short lines to join to keep a pattern around each Point.
Make the First Layer Active. 'Offset - Bothways' these lines.
Turn off the Second Line Layer. Trim lines to suit. Fillet corners if desired.
Save the file as a DXF file.
The easiest way I have found is to save your model as an STL file and open it in Meshmixer. What you need is many 'triangular faces' on your model. to use the edges of these to create your voronoi pattern. There are many tutorials on Youtube.
@JACANT Thank you so much for your response. I have been trying it and watching some videos about it but i couldn´t create a shape like in the photo (cnc plasma cutting) Do you know about any other programme that includes voronoi? Thank you in advance!
