How to get the size of an assembly instance? I do not know the size of the assembly because it has no geometry. The assembly location is not necessarily the geometric centre of all the elements of the assembly, I wish but not the case. Any idea without crashing dynamo to resolve this? Do I need to…

Get the member ids of the assembly then the bounding box(ed) of the elements.

thanks for the response, I already took the bounding box of all the assembly elements and get the bounding box of each and combine and get the centroid of the combined bounding box and the point that I get is identical than the assembly instance element Location. import clr clr.AddReference('RevitA…

the node Elements.solid is a killer, I am not going to do that for sure

with identical density for each of the solids (which is often the case) cordially christian.stan

Use that to build out your python. Teaching you how to fish instead of handing off a completed solution.

centroids = [] #empty list to hold the assemblies for assembly in assemblies: #for each assembly memberIds = assembly.GetMemberIds() #get the member ids members = [doc.GetElement(i) for i in memberIds] #get the members geo = [i.get_Geometry(Options()) for i in members] #get the goemetry …

[image] jacob.small: solids.pop bloody Revit why so complicated, I modified the python script, now makes sense you can see the difference of centroid point between using bounding boxes of assembly elements and solid geometry of assembly elements, but the geometry of some pipe element is wrong…

Might be resolvable via the geometry options, or another bit. Hard to say without a model and I don’t have time to dig into it even if I did. My recommendation is to focus on getting the geometry as you’d expect it to be returned first, instead of solving for all the things at once. You know how to…
