Is there a way to set, for example:
1. A minimum and maximum dimension for a constraint? For instance, I want to model a lever system which uses a linear actuator -- I'm trying to figure out the lengths and pivot points for the rods that make up the system, and would like to restrict the actuator's length to a range of values.
2. A preferred value for a constraint, "I'd like the range between x and y, but closer to x is preferred."
I posted a video of some fiddling with the mechanism here:
