I would like the screw setting to automatically change with the length of the curve to achieve a stretching effect. Here's an example of what I'm looking for. enter image description here

This was made by calculating the distance between the first and last empty. But as you can see it only references the direct distance between the two empties and ignores the actual length of the curve. enter image description here

  • $\begingroup$ @Gorgious That would create/delete screw iterations rather than changing the length of the screw $\endgroup$ Commented Nov 1, 2023 at 21:18
  • $\begingroup$ Oh right I didn't understand your question. you'll have to use a python script and add a function to the driver namespace. the information is not available directly to the drivers functions $\endgroup$
