Dependent expressions

Ernest Atanasiu — Tue, 16 Oct 2018 10:38:20 GMT

Hello there,

In Archicad 22 is it possible to define a property which has a value dependent on another property?
For example: we have a Door Type Schedule where we join uniform items depending upon Type. If I select "Type A" for doors, it would be great to have other properties directly pick up this type and adjust accordingly.
I was looking at the IF ( Logical, ValueIfTrue, ValueIfFalse ) syntax but I don't get it.
Like this : IF "Type" is "A" than Value is "25", IfFalse Value is "10"

Can you help, please ?

Obviously, after I posted the answer, I found the solution.
IF ( {Property:OPENINGS/Type} = "A", "ValueIfTrue", "ValueIfFalse " )

Now the problem still remains. I f I have more than 2 types, how do I organize the expression? The False value should return to a default in all cases but it doesn't since the first expression was already evaluated.

IF Type = A than Value= 01, ELSE = ?
If Type = B than Value = 02, ELSE = ?
If Type = C than Value = 03, ELSE = ?

This is a common problem. The only solution is to 'chain' the expressions, as in:

IF ( Logical, ValueIfTrue, IF ( Logical, ValueIfTrue, IF ( Logical, ValueIfTrue, ValueIfFalse ) ) )

Basically placing a new 'if' statement within the 'FALSE' condition. The last 'FALSE" generally returns a 'N/A' or null string.
