Formula parameters question

[mzmaso90]

Hello Guys, Is there a parameter, set-up within Revit, that establish if a specific room reach the air-lighting requirements mad by the: (Area of glass windows/ total steppable Surface of the room itself?

I need also to set an IF formula with a visibility sintax. Is it possible to have a formula that says: IF (parameter visibility1=YES;parameter visibility2=NO)? And when typing this formula in the visibility script syntax, you can avoid to repeat the parameter of visibility2=NO and just type:NO?

Thank you so much for your time,

Best Regards

Lorenzo

You can't evaluate a Text Parmeter in a formula, but you can evaluate a visibility or numeric Parameter and return Text. 

Example:

=if([Visibility Parameter],"Yes", "No") 

=if([Integer Parameter]<5,"Yes", "No")

Oh, no, not again...

1 < 2, 1 > 2

just...

not(V)

[barthbradley]

huh? 

Oh, I get it. OP wants a Visibility Parameter automatically marked the same as another.
