How to draw a Pipe - making an 90deg Elbow in 2D

[Bowmen]

Hey there,

I took pipe drafting years ago. I forgot the correct steps in drafting a 90 deg pipe bend in 2d (autocad)? Anyone know thanks

If you're just looking to draw the fitting, I'd draw the centerline, then offset, then close the ends.

 

Here's a quick demo for a 6" LR90 (My standard fittings are actually all blocks, but you get the idea)

Any good piping book will have all the necessary dimensions required for drawing fittings.

 

Another option is to skip drawing them yourself and get them as a free download or buy a set of pipe fitting symbols from any number of sources.

I worked at a copper tubing fabrication place for many years, we did tubing this way. Your mileage may vary.

Russ Steffy made a good program for pipe, flanges and elbows.

It will draw regular and segmented elbows.

Short radius elbows - the center line radius will be 1.0 x nominal dia of pipe.

Long radius elbows - the center line radius will be 1.5 x nominal dia of pipe.
