Hello all,

I need help getting a parameter working.  I have a family that has a mfr model number in it that depends on the overall width of the family.  However that width is flexible.  Is there a way I can get the manufactur model type to reflect the width as text with additional text?

I.E.  When width = 30" the model number should be: 689-30  If the width changes to 40" then the model number should be 689-40.

Is there a way to do that?

Thanks,

LJ

There are no text formulas in Revit .

Yes, it is possible.

model (text parameter)

width = length parameter

model = if(width = 30", "689-30", if(width = 40", "689-40", "none"))

But, it is more appropriate to handle this by types, otherwise, you end up with random lengths that do not generate a model number.

If the width is flexible I can easily add a parameter to reflect certain text dependant on the width.  '

I.E: if(Width = 29", if(Rear Access Panel, if(Right Hand, "689R29", "689L29"), if(Right Hand, "689R29FB", "689L29FB")), if(Width = 35", if(Rear Access Panel, if(Right Hand, "689R35", "689L35"), if(Right Hand, "689R35FB", "689L35FB")), if(Width = 41", if(Rear Access Panel, if(Right Hand, "689R41", "689L41"), if(Right Hand, "689R41FB", "689L41FB")), if(Width = 47", if(Rear Access Panel, if(Right Hand, "689R47", "689L47"), if(Right Hand, "689R47FB", "689L47FB")), "INVALID WIDTH"))))

That is actually dependant on three parameters (Width, Rear Access Panel, and Right Hand) in the family.  I just want to add the width number into the outcome of a similar formula.

That's not possible then?

I am saying, it is possible, as in my example, above.

Hey ALfmedina,

We were responding at the same time.  I have a similar equation that you suggested.  But you're right, it's tough when the width can be changed to anything.  The equation I just gave is actually from another model.  this current model will have a variable width that will not be consistant based on types.  But there's no way to reflect the width directly?  

Thanks,

LJ

If you are referring to concatenating any width value into the model text number, no. Only as shown in the example: if this length is this, this text is that. That is possible, concatenating, no.
