Hello GreyDesigns,
If you are using a single mesh and generating different shapes procedurally by scaling them non-uniformly, you might be experiencing a bounds scale issue for sure. Use the images below to toggle the visualizer for the Bounds of your selected objects in the scene, as well as the location on how to change the ‘Bounds Scale’ as well.
Toggle Show - Bounds
Original Bounds Scale - 1.0
Bounds Scale - 3.0
Here you can see how the bounds is affected when I set the ‘Bounds Scale’ value to 3.0 instead of it’s original of 1.0.
Hopefully this resolves your issue, but if you are still experiencing issues, let me know and we can try some more options.
Cheers,
