Info:

In design study, when a new parameter with a global variable which is a driven dimension is added, no action is occurred. After 30 minutes I found out that driven dimensions can not be added to the parameter lists.

What should be fixed:

Solidworks should alert that driven dimensions can not be added as a parameter.

Reproduction of this bug:

In the following file try adding a new parameter with category = Global Variable and from the Reference select box, select height.
