Is it possible to automatically export the floor by selecting the column and the structural frame?
like this
What kind of node should I use? Please advise, thank you
Get the geometry. Convert to surfaces. Find top surface. Get interior perimeter curve.
There may be a less involved way but that should work for most cases.
Can you post a preview of the surface.perimetercurves node? Looks like you have an empty list in the group curves so that’s actually the first issue.
You need to convert your grouped curves to a polycurve before you get the length.
I am sorry, I am still a beginner, do not understand your meaning, I would like to ask what node I need to solve the problem? Please advise, thank you
Polycurve.ByJoinedCurves.
That gets you the outline of your floor. You still need to create the floor element. Floor.ByOutlineTypeAndLevel will get you there.
Thanks for your reply, the problem is resolved
