The heating and ventilation professional heating plan in the CAD construction drawing is a drawing formed by a horizontal projection method and corresponding legends according to building and heating and ventilation component conditions of walls, doors and windows, stairs, the ground, internal functional layout, floor heating and the like of a newly-built building or a structure. Specifically, the method is a horizontal sectional view obtained by cutting the house along a position slightly higher than the windowsill by using an imaginary horizontal cutting plane, removing the upper part, and orthographically projecting the rest part to the H surface. The heating and ventilation plan is used as an important component in building design and construction drawings, reflects the functional requirements of buildings, the plane layout, the planar composition relation and the floor heating laying mode, and is a key link for determining a heating and ventilation system and an internal structure.
