Connection lines angled - not straight

Dear All

I have questions myself quite often why the connections lines of elements when close together always get additional angles and not straight connections. Please see my pictures attached.
If I connect the "T" with the PA-Element the connection line is not straight, but it jumps around in a undefined loop.
I wonder why it is not possible to make straight lines without any angles, etc.

I`m using 0.100.

Thanks

Chris
