Select All Walls of Certain Type on Level

Hi All,

Very new to Dynamo.

How do I select all walls of a certain type on a certain level. I’ve been playing around with the selection nodes in Dynamo but not having any luck. Surely it should be a straight forward script to write.

Any help would be much appreciated.


Use filter by boolean mask
Search this forum for filter by boolean and study what you find

thanks so much!

I have an other question
With which Node I can modify the heights of the already selected walls ?

Hi, I believe you need to feed the elements (from the boolmask), not the element types into the SetParameterByName node.
