Selecting all elements of System Type

[andkal]

hi
Im new to Revit (2 months of experience) and new to Dynamo. Is there a way to select in Revit all elements of the same "System Type" of selected object/ objects?
Im struggling to make it in Dynamo but with no effect. I managed to make a script that selects elements of the same cattegory of selected object and I want to create co something simillar with "System Type", so I can isolate it later.

Packages I have installed for Dynamo:

Depending on what your ultimate aim is, you don’t need Dynamo.

You can set up a schedule, sort/filter appropriately and select all elements by selecting rows in the schedule.

Hallo
Thank you for a quick response. I can also select whole system with System Browser actually.
My goal is to create a quick tool that selects object of the same parameter of selected object/objects. It doesnt have to be "System Type", it can be some other parameter from properties palette.

See below for some basic examples of how to accomplish your goal. 1st example is using system type as you outlined. The second example is using System Classification. Using the system type will not include any mechanical equipment because the system type doesn't exist as a parameter. Using System Classification will include all elements of the system type.
