If the header pipe has already been modeled, and the branch piping started from a different location is ready to be connected to another pipe to form a Tee type piping component.
Example:
Segment E has already been modeled. Segment D originated in a different area of the model but now needs to be connected to the header piping (segment E)
How to form the connection between the 2 pipes at node point E06?
Note: If the intersection point (ex. E06) on the header is missing it will need to be manually added. Use the measure tool to help provide the correct offset along the header for a right angle intersect point.
