The CAD construction drawing has the characteristics of complete drawing, accurate expression and specific requirements, is the basis for engineering construction, construction drawing budget establishment and construction organization design, is also an important technical document for technical management, and can enter a construction stage only by carefully examining the construction drawing before construction, so as to ensure the smooth construction, and avoid the influence on the use stage after the construction is completed due to the fact that the drawing is wrong.
The heating plan of the heating and ventilation major in the CAD construction drawing is a drawing which is formed by a horizontal projection method and a corresponding legend according to the conditions of building heating and ventilation components such as walls, doors and windows, stairs, ground, internal functional layout, floor heating and the like of a newly built building or a structure. Specifically, after the house is cut along a position slightly higher than the windowsill by using an imaginary horizontal cutting plane, the upper part is removed, and the remaining part is subjected to orthographic projection toward the H plane, so as to obtain a horizontal sectional view. The heating plan is used as an important component in building design and construction drawing, reflects the functional requirements of the building, the plane layout, the plane composition relation and the floor heating laying mode, and is a key link for determining the heating system and the internal structure. It mainly reflects the planar shape, size, internal layout, ground, specific position of door and window, heating, etc. Therefore, the heating plan is an important basis for the construction of a newly built building and the arrangement of construction sites, and is also a basis for designing and planning heating and ventilation equipment and drawing a pipeline comprehensive diagram. The heating plan view of the heating ventilation is divided into a first layer plan view and a standard layer plan view. The heating plan of the first layer of heating ventilation shows the arrangement of a first layer of rooms, building entrances, hallways, stairs, floor heating and the like, and the heating plan of the standard layer of heating ventilation shows the arrangement of all layers in the middle and the laying of the floor heating.
With the widespread use of artificial intelligence, some of the work done by the human may be done with artificial intelligence.
