For vertical, called verticalLocating axis.

11、 dimensioning to mark the height of a part of a building.(11111) absolute elevation: our country takes the Huang Haihai plane outside Qingdao as the height measured by zero point.(22222) relative elevation: the base level of each elevation is chosen according to the engineering requirement.Generally
12、, the main floor of the ground floor of the house is designated as the zero point of the relative elevation.Three3333, elevation symbol:Used for individual building elevations; used in total plane iconsFour4444, elevation figures: total plane icon, note to two decimal places, and the remaining marke
