The feature of a plan is that all line segments, points and surfaces are on the same plane, and no element is out of this plane. Therefore, the scheme has the advantages of strong visibility, easy drawing and easy understanding. The properties and theorems of planar graphs are also important contents in mathematics.
Operation steps of floor plan
To draw a plan, you need to follow the following steps:
1. Prepare drawing tools: tools such as rulers, compasses and protractors are needed to draw a plan. You can choose traditional manual drawing tools or use computer drawing software.
2. Determine the basic elements of the plan: The basic elements of the plan include points, line segments, angles, surfaces, etc. You need to decide which elements to draw according to your actual needs.
3. Drawing points and line segments: according to the requirements of the plan, draw points and line segments with a ruler and compasses, and mark the corresponding names and lengths.
4. Draw corners and faces: Draw corners with a protractor and connect corners with line segments to form faces according to the drawn points and line segments.
5. Inspection and correction: After drawing, the plan needs to be inspected and corrected to ensure the accuracy and integrity of the drawing.
Application of floor plan
Plane is a basic concept in mathematics, which is widely used in geometry, topology, computer graphics and other fields. In real life and work, planning also has many applications, such as:
1. Architectural design: Architects need to use floor plans to plan the architectural structure and spatial layout.
2. Map-making: Map-makers need to use floor plans to draw maps, and mark geographical location, topography and other information.
3. Engineering construction: Engineers need to use the floor plan to plan the construction scheme and determine the project progress and workload.
4. Mechanical manufacturing: Mechanical manufacturers need to use floor plans to design mechanical structures, parts, etc.
