I can create / adjust the size of a torus created using Geometry Nodes but the changes are affecting the entire object in more than one axis / settings. Example of an issue, if I change the outer radius the inner radius also changes see animation below.

Node Setup: img1

Example:

  • I'm trying to have the outer radius only affect the outer radius.
  • I'm trying to have the inner radius only affect the inner radius.
  • I'm trying to have the height only affect the height of the object so if I type in 2.4mm the height will be a a total of 2.4mm from top to bottom.

I know this can be done with the torus object but the goal is to use Geometry Nodes to learn it.

Issues.

This will be used to create custom 3D printed washers and o-rings.

In the Add > Mesh > Torus context menu you can originally switch between the "Major/Minor" method or the "Exterior/Interior" method to create the torus.

With the following Geometry Nodes nodetree you can choose between those two methods as well: it has a boolean input to select which method you want. 0 (False) means "Major/Minor" whereas 1 (True) means "Exterior/Interior" method.

The other inputs define the major and minor radii resp. exterior and interior radii according to the chosen method.

EDIT: Sorry, I forgot you want to control the height as well and added it.

EDIT 2: Before it gets too boring you can add more nodes and a boolean input to decide whether you want a washer with a circular / ellipsoid profile or a flat washer:

    $\begingroup$ Without dividing the input values by 2 you should call them outer and inner diameter instead of radius. $\endgroup$
