How to draw street lamps in architectural cad? plane graph

Architectural cad street lamp representation;

When the survey area is small and the radius is less than 10 km (even 25 km), the water level can be used instead of the horizon. On this premise, the ground scenery in the survey area can be projected onto the plane along the vertical line, and the similar figure formed by shrinking according to the specified symbol and scale is called the plan.

In design, computers are usually used to calculate, analyze and compare many different schemes to determine the best scheme; All kinds of design information, whether digital, literal or graphic, can be stored in the computer's internal memory or external memory, and can be quickly retrieved.

Designers usually start with sketches, and the heavy work of turning sketches into working drawings can be handed over to computers. The design results automatically generated by computer can quickly make graphics, which is convenient for designers to judge and modify the design in time; Computers can be used to process graphic data related to editing, enlarging, reducing, translating, copying and rotating graphics.

Application of CAD in civil engineering;

1. Architecture and planning design: used to draw architectural and planning drawings, such as architectural construction drawings, renderings, planning renderings, bridge modeling design, etc. Its software includes Tianzheng Building Software, China Architectural Research Institute APM (the building module of PKPM), QXCAD (a bridge design software), 3 D M A X, MAAYA and DESIGN. Structural design refers to structural design.

2. Water supply and drainage design: used for calculation and drawing of water supply and drainage;

3. HVAC design: used for heating and ventilation design;

4. Electrical design: strong and weak current aided design;

5. Construction organization design: used for project management of construction projects, process design and optimization of construction technology, construction site layout, etc.

6. engineering budget and final accounts: in a broad sense, this is also an application of C A D in civil engineering;

7. Other aspects: such as home decoration.
