thanks, I have seen, in this the objects of the various planes can move together.

But:1) however it remains a strange thing. The floor level (ELEV 1 etc.) remains unchanged. So even if the sketch adapts to the height and the objects as well, the measure set remains on the mask of the Floor dimension (only can be entered with a number). So what can be done?

2) how do you link the original sketch to the objects so that they cannot move separately? (in fact if I numerically change the height of the Floor, the sketch moves the objects but the sketch remains still)

3) on version 0.18 does not appear the formula put in the Formula editor, while it appears on version 0.19?

4) where can I find the instructions of what I can write in the formula editor? (Otherwise, most people are excluded from this possibility)

Then I agree that the way level offset is written doesn't seem adequate
