Sensor Custom Feature

Would it be possible to add a wall thickness checker or would this be better off as a new feature script like we have with the draft analysis.
The company i work for are injection moulders and one of our common checks is to check the wall thickness prior to tool build. At present we have to use an external package like moldflow or Altair.

That might be a bit beyond what is capable and efficient for a custom feature. We do have an improvement request for a built in wall thickness tool.

I too would use a wall thickness check. I'm sure it will become native functionality at some point (like draft analysis), but there might be a way to do it with featurescript as a stopgap. I can't really think of any efficient way to do it though. The best I've got offhand is to cut the model into tiny cubes based on your thickness threshold, then check if the volume of each section is bigger than it should be, but that would probably be buggy and take forever to compute.

What if you input the inside surfaces, then the outside surfaces, and created a "mesh" of points across each inside surfaces. Then, measured from those points to the nearest outside surface and returned the distances for each point. The points with distances beyond the chosen tolerance could be debugged as red.

This would be a good tool to have, can you please add me to the improvement request list.

Here's the IR in case anyone else is looking for it: https://forum.onshape.com/discussion/10002/thickness-analysis-tool

That has more promise than my idea.

how do I add this sensor to my project? (total newbie...) Can it also be used dynamically in an assembly while animating a mate?

Sorry. Off track.

To add the feature to your toolbar you can click the + Custom Features button and then click the feature in the list:
