Hey everyone,
I want to grab the bottom of Linkedfile CLT structural columns to draw Room Seperation lines around.
But I do not know how to go from the columns to the bottom circumference. Any ideas?
Wow brilliant, never thought of using the level plane as a intersection to get the bottom surface. Brilliant. I will test this right now
I used your top screenshot as a reference, but I added an element filter to get CLT columns. Instead of using the active view, I used “Views” node to pick a view and use it’s sketch plane to make it user friendly.
I also added a filterby boolmask and checked whether the column actually intersects with the plane first.
Unless the view’s cut plane is used instead of it’s base level. Then I might have to change that
yes in my example i assume your room is on level 1 and your columns as well…it was just an fast example…yeah many situations and ways here 
Linked files should have options “Room boundaries”.
Also try Element Surfaces References from GeniusLoci package.
yeah dont think roombounding from link do any difference as it isnt for the structural columns as the dont have any room bounding option only architectoral column have it i guess if i remember right
Yeah and I only want the CLT columns. The other ones we don’t consider room bounding anyway.
The Element Surfaces References doesn’t help because I cannot get the bottom of the columns consistently
Structural columns do have a “Room Bounding” property as well- but as the original poster is not in control of the linked file, your approach is the way to go probably.
hehe @Joe.Charpentier thanks didnt know that am not the big structural-column guy
The linkedfile model structural columns are even marked as room bounding, yet they don’t come through well enough. Since having an overload or overlapping Room Seperation lines isn’t that big of a deal, I chose to just generate them with a quick blunt force tool that doesn’t require me to triple visually check
