Offset top constraint of walls

Hello everyone!

New to Dynamo and I have a quick question.

I’m sitting in a school project, creating an apartment building, and I need to offset all of a specific type of wall by -400mm of their top constraint.
I’ve been trying to do it through Dynamo with no luck.

Can anyone help me out?


First Select all the Walls you want to Offset. (Get a 3D view and select all instances of that wall and isolate them, this makes selecting them easy)
Read out the Top Offset parameter from the walls and substract the -400mm
Set the Top Offset of these walls again with the new Value

You can also select all walls of a specific type in Dynamo. Something like this below

Thanks a lot, this really helped me! :slight_smile:
