How to use pathing tools properly

[triton]

Hello,
So since few days I try-hard to have some behaviors I would enjoy as a player and as a spec. Here is my question how to tell this commander to walk around this group of units?



Also if my commander cannot reach it's destination, why is he trying for infinite amount of time?

Also even if pushresistant = false, when some constructors are guarding another constructors, they seems to block it very often, and cannot be pushed away even if they are blocking the cons they are guarding.
