Anonymous users2024-01-23Three meters high we generally press the 500mm high ceiling, but you only have two meters eight, I think I 400mm is more reasonable, the height of the general ground to the ceiling is the most common!
This is the elevation, which is the representation of the height from the horizontal, generally positive numbers do not need to add a "+" sign, and negative numbers need to add a "-" sign. In the ceiling diagram, there should only be a positive number of elevations, and negative numbers are generally in the floor pavement drawings such as bathrooms or basements.
If you can do a floor plan, these ceiling circuits should not be a problem, as long as the socket switch is determined to maintain a good height, there is nothing to do, show you a few ceiling circuit waterway diagrams.
What do you do? Home improvement or sprinkling.
You want to find the horizontal position of plus or minus in the drawing, and the negative number is the value of that position downward, for example: smallpox is plus or minus. >>>More
