How to draw a CAD single-line diagram
Thread Content
Please, an expert, explain in detail the steps for drawing single-line diagrams – mainly how to draw various pipe fittings, and whether it’s necessary to use other auxiliary software

There are basic explanations in HG/T20519
It’s something like this: I mainly want to figure out how to represent valves, elbows, and branch connection plates – should I create a new block for them or use some special symbol?
Search for images online; they all have a fixed format.
Refer to the standard and draw it by yourself; draw one, and then copy the others
It can be drawn quickly using my program. Here is the operation video of the program: https://www.bilibili.com/video/BV1Eh4y1G7aU/. You can download the program by joining the QQ group 53096376
