I've been learning and trying to grow my knowledge in using formulas when creating families. My most recent task has been trying to take an individual workstation and through visibility options making it flexible enough to copy, modify its properties, and group into a grouped workstation.

----See attachments for clarifications------

Parameters: End Wall1

Intermediate Wall

Side Table1

PROBLEM: The problem I'm having is with the visibility of a side table (Side Table1). I need Side Table1 to turn off when End Wall1 is off and I would ideally like to use a NOT operator since End Wall1 and Intermediate Wall currently have a NOT relationship setup. If I understand how the NOT operator works then when the Intermediate Wall is checked Side Table1 would be turned off. The problem for me is that I currenlty have a formula set up for Side Table1 that relates it to another parameter and I am unsure of how to combine these two conditions into the formula field.

Alternative approaches are also welcomed.

Thanks

After a few days of letting the information sink I solved the visibilty problem. I'm unsure how efficient it is, but it works.

For those of you also learning, I ended up breaking the visibilty parameters for the side table into two. One paramenter (Wall Table1) controlls the visibility relationship with the the Desktop Width parameter, essentially a relationship based on dimensions. The second parameter (Side Table1) controls the visibility relationship with the End Wall1 and Wall Table1 parameters, essentially a relationship based on On/Off, through an OR operator.
