My platform TCAD 21.2 build 71.0 running on HP 350 G1 6GB RAM, Core i3 4005U 1.7GHz, 471/680GB on HDD available. Win10.0.15063.
I am trying to make a model whose dimensions consistently read to .0005". Even just making the box to start out with, I have to police the dimensions and re-input them, because they keep changing. When I snap the handle of an object to something, I have to correct at least one dimension, which goes off by an amount that is often more than .001". By the time I have done two boolean subtractions, policing the dimensions and coordinates at every step, and keying in every dim to .000001", there is still a linear error in some places up to .02".
What on earth is going on?
