blockages with auto-updating altitude

[Dedalo77]

hi, time ago in the study where I worked, we had some altimetric self-reaching blocks, in the sense that if you set the origin of the axes in a consonant manner, every time you moved the block quota on the section, to different altimetries, this was automatically updated with the exact quota of the point, I asked several times to the architect how to create a block of the genre but the answer was always I do not remember.....
Can any of you tell me how to create such a block?

Thank you.

the proposed system is valid but has a disadvantage: we imagine having inserted the blocks on a section; then if for some reason I move the whole section, i.e. I do not move the single block because it varies the quota, but I move all the design ... the quotas become wrong. (correct me if I'm wrong)

I have adopted a different system (you can see it from the attached design): I created a quota style that has everything invisible, except 1 of the 2 arrows ... (using an appropriate block).

I couldn't eliminate 1 quota line from the 1st point to the point of altitude, so I made it invisible, changing the type of line.
to do this I created a type of "invisible" line, editing the acad.lin file

on the drawing you will find the 2 lines to write in acad.lin to get the new type of line.

This system has the advantage of allowing the move of the entire section, but when we want to change a quota, we simply iron it or use the grips.
