Good morning Tony,
Here's what I 've got:
I have checked the origin point of the valves and that is in the center of the valve. I think that is where it should be.
When I move the valve, the opening in the pipe stays where it was, the valve is moved to another part of the pipe, no new opening is made.
The command "pid component redraw all" doesn't change the situation.
Above is tested with elements converted from plantspace pid.
When I place a new valve on the existing pipe then it behaves as it should, the pipe is interrupted over the entire length of the valve and if I move the valve the opening moves with it.
Do you know of any other tests I can run to find out where it goes wrong?
Kind regards.
