How to draw section symbols in CAD
In CAD design, section symbols are an integral part of engineering drawings and are used to indicate the section position and direction of objects. This article will introduce in detail how to draw section symbols in CAD, and provide you with comprehensive guidance based on hot topics and hot content in the past 10 days.
1. Basic concepts of section symbols
Section symbols usually consist of section lines and arrows to indicate the location and direction of the section. The section line is a dashed or dotted line, and the arrow indicates the projection direction of the view.
| symbolic elements | Description |
|---|---|
| Section line | Dotted or dashed lines indicate the cutting position |
| arrow | Indicates the projection direction of the view |
| letter logo | Used to differentiate between different section views |
2. Steps to draw section symbols in CAD
1.Draw section line: Use the "Line" or "Polyline" tool, select the dotted line or dotted line style, and draw the section line.
2.Add arrow: Use the Leader tool or a custom arrow block to add arrows to both ends of the section line.
3.Label letters: Use the "Text" tool to add a letter logo (such as "A-A") near the arrow.
4.Adjust style: Adjust line style, arrow size, and text style as needed to ensure symbols are clearly visible.
| steps | Operation |
|---|---|
| 1 | Draw section line |
| 2 | Add arrow |
| 3 | Label letters |
| 4 | Adjust style |
