So, the thing is: I was trying to make sure that my door family has, at least 9 cm thickness, even if it were placed on a thinner wall. Then, I used a parameter called "EspessuraParede" (that means WallThickness, in portuguese) to measure the thickness of the wall witch the door would be inserted into (obviosly).
So then, I created a parameter called "Espessura" (Thickness), that was about the door thicknes.
After that, I used the formula: IF(Espessura < 9cm, 9cm, EspessuraParede) to make sure it would always have 9cm or more. But, Revit didn't accepted my formula, sayin that it would be a loop, circle references, or somethink alike.
Why am I having this warning, if, with my wall is initially a 15cm one and doesn't satisfy the IF condition?

the formula looks ok to me. it is probably referring to how the elements in your family are constrained using these parameters. check where these constraints are being used and locked to in your family.

Your formula looks like this
Thickness = if(Thickness < 9cm, 9cm, WallThickness)
The loop is the parameter Thickness. You cannot control a parameter by itself. It should be like follows
DoorThickness = if(WallThickness < 9cm, 9cm, WallThickness)
The formula will control the geometery of the door based on the wall thickness

So let me see if I got this... thickness would be a number paramenter, just to be inserted by the user, and doorThicknes would be the one associated whith my door, measuring it?
Original reply was edited...door thickness should be controlled by the wall thickness no need to input anything
DoorThickness = if(WallThickness < 9cm, 9cm, WallThickness)
