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?
-Thanks!
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!
