Trying to add window option to overhead door

[patricks]

I'm trying to add the option of having view windows in our overhead sectional door family. I set up an array for number of windows of 2 or more, then a single center window for one, and visibility parameters controlling the single and the array, all of which are controlled by a "Number of Windows" integer parameter.

I have a separate "WindowNum" integer with a formula that keeps the array number at a minimum of 2 (if Number of Windows is 1 or 0) so that the array doesn't break. However even if I set Number of Windows to 1 or 0, it says the parameter has an invalid value. Can't seem to reconcile this thing. Any ideas?

You need to create another parameter for your array so that the arrays value doesn't go below 2. I created a parameter "Number of windows array" with the formula "if(Number of Windows < 2, 2, Number of Windows)" and assigned that one to the array and it's working fine.

See attachment created with student version of RAC 2012.

Oops, I forgot to set the array to my WindowNum parameter. I already did earlier what you suggested, just forgot to set the array itself to the correct parameter.
