Excuse me, what do these symbols on the villa design drawings mean?

Door and window symbols: usually represented by simple lines and shapes. The symbol of the door may be a "|" shape, the symbol of the window may be a rectangle, and sometimes the glass is represented by crossed diagonal lines.

Wall symbols: usually represented by straight lines or thick lines, representing the external walls and internal walls of buildings. The symbol of the wall may be a straight line, and the corner will be represented by a small angle symbol.

Stair symbol: usually represented by a set of parallel lines or arrows, indicating the position and direction of stairs. Arrows may indicate that stairs are up or down.

Electrical symbols: Use specific icons to represent different types of electrical equipment, such as sockets, switches, lights, etc. These icons may have unique shapes and marks to distinguish them.

Water pipes and pipe symbols: Use line segments and arrows to indicate the direction and connection points of pipes and water pipes. Arrows can indicate the flow direction to distinguish between cold water pipes and hot water pipes.

Furniture symbols: commonly used furniture such as beds, sofas, tables, chairs, etc. Can be represented by simplified icons. These symbols can help determine the layout and position of furniture.

It should be noted that the specific symbols and their meanings may vary depending on the designer, region or design drawing type. If you encounter ambiguous symbols when looking at design drawings, you'd better consult relevant designers or professionals to get an accurate explanation and understanding.
