Hi Guys I need some help with a Curtain Panel Parameter I would like to create.

I have created a Yes/No instance based parameter for a curtain panel which I can currently manually set.

I am trying to create an IF Parameter that would link to the panel & trim it if the panel drops below 1000mm wide.  The Curtain Panel I have used in the curtain wall is actually a STD wall type for window & door hosting etc.

This is what I've come up with so far after reading a few different sites, however I am getting an error message telling me that I cannot link to another parameter 'Length'.

=IF (Length=<1000, Trim = 1<2, Trim = 1>2)

Any advice would be much appreciated.

Not sure what the algorythm looks like but when I see your formula I would write it like this for the Trim parameter formula


if (LENGTH < 1000 mm, 500 mm, 400 mm)

This formula equates to 'If the length is less than 1000 make trim 500 else make trim 400."


If this is not exactly what you want it may help you figure it out.


See image.


If Trim is a Yes / No Parameter it gets really simple becasue you can skip the Then, Else.

=IF (LENGTH < 1000)

This equates to: 'If Length is less than 1000 make trim 'Yes' else make trim 'No". No need for the Then or Else aspect.
