Robert, what is the name of the icon/tool your red arrow points to? I do not see that anywhere on my toolbars.

To clarify, can a polyline as a single unit exist in a T shape? See attached T-shaped polyline. Basketballman, your idea is a workaround, not an answer.Polyline.plan

I am using the molding polyline tool to model HVAC ducting and plumbing. How can I create a T intersection in a polyline?
