# Left, right ups and down references for Dimension

#1

Hello dears,
i want to make a dimension for all Structures columns like this

the problem is how can i select the left or right references or up & down, to make the dimension
i have tried the Genius Luci nodes but it give nulls

Any ideas ?

This only works if the references are defined in the family.

See if this helps…

Apologies for the mess, I’m working at speed Hopefully you can optimise and adapt it…

If the columns are all rectangular then that will help… You know that you will (almost) always want faces 0 & 2 and 1 & 3 for your references etc.

Alban has a Dimension By References node which I would use…
