Getting parameters from a list of catagories

[pega]

Dear experts

I have now attempted to work this problem out myself and looked through the forum without any luck.

My problem is that I have a list of all categories from my Revit model. From that list, I want all elements of the categories. And from that, I want all the classification (custom parameter) parameters of the elements.

Anyone that can help me with this?

Kind regards,

Peter

hi Peter
Try to see this post and the entire post in general.

Collect all categories in a project

subscript First, I have to admit that the dynamo team have provided nodes that could do exactly what I tried to code in python, namely colleting all elements by a list by “Natural Category Name”. Secondly, have I turned the code collecting elements that has materials into a node named as Element.HasMaterialQuantities". The node are now included in the “DanEDU Dynamo” package.

…and

I have built some graphs for this for the CCS classification, if you plan to do that

• with smaller adjustments would BIM7A (SfB) or FK classification also be doable.

I can do classification of type, instance and location id

Here is a solution for your question

The model used for this, is the “University Building.rvt” that can be found at http://www.bim.byg.dtu.dk/DanEDU-Lokalizer-UK in the Example Collection (2017 and 2018 versions)
