Tools for drawing single-tube diagrams

We are still using CAD; although it wasn’t very convenient at first, as more time passes and more data is accumulated, it becomes workable. I’ve also been looking for something simple, easy to use, and straightforward to get started with, but I haven’t found it yet. This post was last edited by xsj1972 on 2009-3-3 09:21]

Is it in 3D format using CAD?

We all use PDS for piping work; once the pipes are prepared, it’s just a matter of creating drawings, and there’s no need to keep track of materials or fittings, as all the necessary information is already available.

It would be best to use 3D software, but someone needs to create and maintain the database. CAD tools -> Draft Settings -> Snap and Grid -> Snap Type -> Isometric Snap can also be used for drawing, but one has to label everything manually and keep track of materials, which is quite tedious

If the preliminary work is done well, it’s very convenient to create drawings using 3D software.

Use 3D software to create the model. . It automatically generates bill of materials diagrams, including material information, and allows for control over the generation process. . A skilled process is required beforehand.

Using CAD directly is very convenient; you just need to make a few settings. Right-click on the polar axis – Settings – Point Capture and Grid – under Capture Type and Style – Isometric Capture – OK. By matching the XY coordinates on your plan with those here, it’s easy to draw a single-line diagram. It’s my personal *habit.

The most commonly used software is CAD, but this isn’t necessarily the case in professional design firms.

We used Microstation and CAD R14 to draw it

There are more steps involved in drawing with Microstation compared to AUTOCAD, but both programs present difficulties when drawing curved pipes. CAD has some advantages in terms of dimension marking, but it’s tricky to draw ellipses. It is recommended to use CAXA Electronic Drawing Board.

Using CAD, it’s not very convenient at first, but once you get used to it, it’s quite good.

My personal habit: I use CAD directly and set it up first. Right-click on the polar axis – Settings – enable Polar Tracking, set the incremental angle to 30°, create several additional angles: 30°, 60°, 90°, 120°, 150°, 180°, 210°, 240°, and then click OK. When drawing, auxiliary angle lines will appear. It’s time to draw.

Of course, when creating single-line diagrams, PDS is the fastest method for extracting ISO data. However, the initial workload is quite substantial, and not every organization is willing to use PDS. CAD is mainly relied on for creating single-line diagrams, and this requires time to build up expertise; it’s indeed troublesome at first, but it becomes much easier later on. One can create smaller sections and insert them directly. I just uploaded a program titled “Industrial Pipeline Single-Line Diagram Drawing Software” in the engineering resources section – it can be used to create single-line diagrams directly. It was developed by a certain faculty at a university. Unfortunately, it doesn’t allow conversion between formats and CAD, but all the functions can be accessed by simply clicking on them. If one only needs to generate diagrams without using CAD, it’s very convenient to use
