Very common story that surprised me a lot. We just set a dimension to a global variable and WOW!
1 we have a globalVariable and a dimension
2 we set the dimension equal to this variable
3 ok the dimension is made equal (linked) to var
4 we change the dimension type to diameter (as we intended according to the variable name)
5 we begin dimension edit to set it correct because it is not the value we want
6 we again set this dimension to global var
and WOW it changes the global variable!
why? and are there other manipulations that can implicitly and unnoticed change global variables?
