lookup state error

[zweiser]

I am trying to recreate what I did for the screw block on the right.

the block on the left should change visibilities consistently, but when it it stretched at a lower distance from 2", too 2" it does not work, but will work from a higher distance from 2" too 2"

It's because you have the parameter drawn at 2.00001132 and the list value is 2.00001132, but the lookup value is 2.00000000.  That discrepancy means that the value of the parameter never matches the value of the lookup.  Set the system variable LUPREC to 8 to see the discrepancy.  I actually have a LISP routine in my startup suite that (among other things) ALWAYS changes LUPREC to 8 as there is no reason to have it set lower.

That fixed it, thank you. I had my precision not that high, I would have never thought about that
