Formula with YES/NO with if

[DanielLemen]

I would like to know how I made my object. I've made 2 part "Graphics" "Visible" that i would like to trigger some how.

I would like to manage an IF statement like this

IF Tibi 600 then

Part 600

else

Part 400

ENDIF

HOW do I made that in Revit? 

And then put into my .txt files Tibi 600##OTHER## 0,1,0,0,1 and sooo on. 

Very simple questions but I really do not understand this in Revit.

if statement is like this:

if(condition,result if true,result if false)

In your case:

The parameter called Part is defined by formula   if(Tibi=600,600,400)

I've been reading if(condition,result if true,result if false) but have no clue how to use it. I'm not thinking right. 

But I wonder could u made a simple object so I can see?

Tell me what you want, do you want to control the visibility of an object or its length? What is your condition?

[Ilic.Andrej · Accepted solution]

For example, if you want to control the visibility of two objects, create three yes/no parameters (for example, one is called "a" ,the other one "b" and the third one "Tibi"). Select objects and look at their properties, next to the param called "visibility", there is a button. Click it and assign yes/no parameters that you created. First object is constrained with param called "a" and the second one with "b".

Now, open family parameters dialog. For param called "a", asign this formula

Tibi

For param called "b", assign this formula

not(Tibi)

So whenever user clicks "Tibi", he will turn one object on and the other one off.

I'm really guessing here what you want, you need to explain a bit more....

This is what I asked for. Thanks alot! 

For me it's hard to understand it. not(Tibi) was the answer I needed. That's to easy 😛
