Hello Dynamo community. I’m am currently working with a project where a need to make a list of all elements in the project, with there name and classification code, At this point I know how to do that with one category, but I would like to know if any of you knew a way , so I can select all the c…

Like Tomasz says it’s probably easier doing this with nodes: [image] This will also get you all annations families though. If you want to use this for take-off then you’re better of creating seperate category nodes and combining those into a single list like so: [image]

You need a reference for Collections.Generic. Try this: from System.Collections.Generic import *

That kinda worked, now there is not a fail but the list is empty

you probably want this as well. This will wrap Revit API elements into Dynamo clr.AddReference("RevitNodes") import Revit clr.ImportExtensions(Revit.Elements) Also do you have doors in that project? I mean, this is a multi category element collector not a Category collector. It returns all element…

okay so the node called get Categories with builtins would be the one to use ? and thanks again for all the help :slight_smile:

[image] Super Collect Elements from Document For model checking and auditing, it is often useful to be able to collect every single element from a Revit model. One way of doing this is to use the built in Category list, and then loop through …

Just getting every model category in the model bothered me for a while as well, so I finally got this working: [image]

I just feed the desired Built in category names to my super collect node, not all of them.

Sure, it’s part of my package: MEPover import clr clr.AddReference('RevitAPI') from Autodesk.Revit.DB import * clr.AddReference("RevitNodes") import Revit clr.ImportExtensions(Revit.Elements) clr.ImportExtensions(Revit.GeometryConversion) clr.AddReference("RevitServices") import RevitServices fro…

That is indeed true. The API documentation also mentions this: "The category type determines if the category is shown in the Visibility/Graphics settings grouped with the model,annotation, or analytical model categories. Note that import categories are also “model” but will be shown separately in th…
