tip for creating plan regions on ceiling with variable height

[ROSIE_SG]

I have a lot of pipes in the ceiling

the problems is that the height of the ceiling change so i need to create a lot plan regions.

there is any faster to make plan regions without using sections all the time to check the height in the specific area?

Is it a floor plan or a reflected ceiling plan?

floor plan

but i can use ceiling plan if it will help

Is it the ceiling which changes heights or is it the soffit of the floor/roof above which changes?

Maybe post a screenshot of the section through the problem area?

i make a section in a place which you can see the difference of the ceiling height.

If your plan view discipline is Mechanical or Plumbing I don't understand why you can't just set the top plane to the highest level - the ceiling/floor will be wireframe  and won't interfere with the visibility of the pipes. You don't even need plan regions, just adjust the view range:
