Dimension.byElements error

[Rickkrrd]

Hello,

I am trying to make dimensions depending on these 2 elements. I keep getting this error and am not sure why. To me, it seems that the elements aren’t properly implemented, as the argument type is “_.array”. Am I doing something wrong or do I miss something?

Small note; the elements are part of an assembly that I want to keep

Removing the Element.Geometry Node gives:

Are my Elements not compatible for dimensions?

Thanks!

Hi,

You need to extract element geometry which has references enabled (as an option) in order to dimension. It is possible that your elements don’t have references, but most will.

This post might be useful?

Reference a geometry of generic model

So I wan’t to get a geometrical reference of a generic model. I’m able to get solids but how to get a reference to its faces? I’m inspired by this post of @MartinSpence Multiple Spot Coordinates [image] import clr clr.AddReference('RevitAPI') import Autodesk from Autodesk.Revit.DB import * clr.AddReference('RevitServices') import RevitServices from RevitServices.Persistence import DocumentManager from RevitServices.Transactions import TransactionManager clr.AddReference('RevitNodes') impor…

I think the genius loci package has quite a few useful nodes for this kind of thing.

Hope that helps,

Mark

Hi Mark,

Thanks!

Genius Loci did the trick with Dimension ByReference. I will look into a Python code, but at least it works
