@barthbradley I write two examples.
Not undrestand what are you referring to. One of this?
For first:
"You have locked the dimension between 2 and 3" ==> I locked evry dimension beteen level and then try to change upper level quote
"and then changed the dimension from 1 to 2 to a greater value than it presently shows." ==> no
"What direction can 1 possibly go if 2 is immovable? 1 can only move in the opposite direction." referring to what @ToanDN say before, that have to select level opposite of where want to go my level?
If you were to pull a dimension from 3 to 1 and lock it, then PIN 1 and change its dimension, then 2 and 3 would move up together; and 1 would stay right where it's at.
For second:
"You have locked the dimension between 2 and 3" ==> no lock between 1 and 2
"and then changed the dimension from 1 to 2 to a greater value than it presently shows." ==> I change between 2 and 3.
Do not undrestand. But undrestand that if want that my level go to a side have to click on the opposite level I want the level want to go and than change dimension.
