if we change the width of a volume to a size, but later decide to change this back to NO value so it equally distributes, how do we do this?
Answer (But scroll down for word of warning):
Before we do the Reset always change the width to use a hardcoded value (instead of a parameter or a formula of a parameter e.g 1*t (we found it was hit and miss with formula but success when hardcoded value))
To change width of volume go to Modify Parameter > select the volume (face or edge) to bring up the parameters
Select Width button > then REPLACE button > enter hardcoded number
Once this has been done, go to the tree, select stub and then Reset.
