DI T-Piece

[Happyunited]

Just a query I’m currently stunk on.

I am trying to connect a 1000dia pipe into a 1400dia pipe but it doesn’t seem to want to put in a t piece. The angle is 45deg. Is this something that I should be able to access within Revit or would I be quicker drawing the piece myself and importing it in?

Thanks in advance for your input.

Is that fitting defined in the properties of the pipe?
Is your pipe sloped?
