How to change the element System Type using Dynamo

Revit
1

Hi Guys,

I am very new to DynamoBIM, and I need you guys to help me do my first program.
I want to change the system type of an element from one to another.
For e.g Duct system type change from “Supply Air” to “Supply Air Duct”.
Note: Both type system classification is same, which is Supply air
I uploaded a screenshot for easy understanding.
Please guide me to get it done. I tried few methods, its not working for me.

Hi @santhorathi

Use Element.SetParameter node and connect your desired system type.

Hi @Kulkul,

Hi, actually Now I can’t create duct routing with other system classification, which means I can’t create a Return or Exhaust system. If I create a Return Air system it automatically change to Supply Air.
What I want is, I have few System types under same system classification (Supply Air)
System Types.

  1. Supply Air,
  2. Supply Air Duct,
  3. Fresh Air Duct,
  4. Pre-Cool Air Duct.
    All the above are under Supply Air system classification.
    What I want is, Supply Air (System Type) should change to Supply Air Duct (System Type). The remaining item’s 3 & 4 should be remain.
    If I understand properly, this program change all the ducts to one system type.
    Please help me to look into it
    Attached screenshot for your reference…,

    Thank you so much for your kind support.

If I understand correctly you have ducts modeled as Supply Air, Fresh Air Duct, and Pre-Cool Air Duct and you want to change only the Supply Air systems to Supply Air Duct. If that’s correct you need to filter your elements before you change the type.
