Changing variable value breaks sketches inconsistently

paul_botwidpaul_botwid Member Posts: 6

In modeling a parametric box design, I encountered some weirdness when working with variables to control the boxes dimensions. 

Basically, when I change a parameter / variable like the box height, it often breaks one of the sketches. 
However, if I go into the affected sketch and do a slight change, like adding 0.1mm to a dimension, the new variable value works. 
After this, if I go back and reset the dimension to the original value (then didn't work the first time) - the sketch still works out. 

Bit hard to explain but please see the attached video and maybe it's clearer. 

Any thoughts as to why this might happen and how to solve it?
Is it just a bug or is there something I can do to prevent it?

Thank you
