As I am testing out Plasticity for projects involving game development and 3D printing of wearable hardware and tools (I use Modo mostly for this), what I think would be useful for those who build parts that need to fit together is an option for setting a fit tolerance during Boolean subtractions.
Example, the red cylinder is cutting into the box, and if I were to print the box and cylinder, they would not fit at all.
In order to get around this, after committing to the boolean, I have to select the faces that I cut and set a negative offset value (the faces push away from the other solid) which allows the part to fit snug after its been printed.
