This quick tutorial uses geometry nodes to create basic 3D drawing tools. Having watched the tutorial, I developed the tools a little by adding sliders in the Modifiers menu to make them easier to adjust.

There are three tools, which I have called:

  • Draw 3D Pipes
  • Draw 3D Merge
  • Draw 3D Cushion

They each make use of the ‘Draw’ tool in Blender’s Edit Mode, which allows you to draw freehand splines.

The tools are fun to use and really easy to set up.
