Structure Connection

[HJiang85U97]

I'm new to use connections for steel members and have a question. 

Trying to create a customized a connection but the tab is gray out:

I'm using Revit 2025.

No worries. Figured it out.

Glad you got it sorted, I assume it was because you need to have a Connection in place already to activate the Customize options?
