Allow binary outputs for yes/no parameter conditional statements

Allow binary outputs for yes/no parameter conditional statements

When setting yes/no parameters with a conditional statement, Revit currently requires that you set the result-if-true and result-if-false values via true and false mathematical statements. 

 

 

test         = 90 mm
test1  [√]   = if(test=90 mm, 1=1, 1=2)
test2  [ ]   = if(test=90 mm, 1>2, 1<2)
test3  [√]   = if(test=90 mm, 1<2, 2<1)
test4  [√]   = if(test=90 mm, (1+8/2+1)>2+3, 1=2-1)
test5  [√]   = if(not(test=90), roundup(sqrt(test/1mm)/2)=4, 1=abs(rounddown(tan(test/2mm*1°))-2))

 

 

This method reduces readability, and increases the chance of errors.

 

Most other languages handle conditional statements by allowing the user to either use the words 'true' and 'false' to state the output, or allow for binary states (1=true, 0=false).

 

 

test         = 90
test1  [√]   = if(test=90, 1, 0)
test2  [ ]   = if(test=90, 0, 1)

 

 

To me, this seems solvable by simply altering how parameter formulas perceive 1 and 0, when used as a function for a yes/no parameter. I would really appreciate this, and it would greatly improve programming of parametric models, and their subsequent testing, stressing, and validation.

 

PS.

Yes. That last formula works...

You are over complicating this. Yes/No parameters don't need an if statement for a formula. All you need is "Test=90mm". If its true, the parameter is toggled to yes. If its false, its no.
