# how to draw a three way pipe this ones got me stumped any help much appreciated thanks.

this is a three way pipe, the two smaller pipes sticking out have different heights and angles and also on an angle to each other have included a small sketch to try and explain what I'm trying to draw, pipe diameters doesn't matter, its just getting the sketch right that I'm looking for, any help thanks .

I'd recommend doing it with 3 sketches, because of the angular offset shown in the 'top view', and also anticipating the use of the swept boss/base feature to create the solids.

First draw the main pipe on a plane of your choice, 'front' or 'right' seem like good candidates, then do a second sketch on that same plane of either of the side pipes. Your choice.

After that, you can create a plane through the main pipe and at the 40deg angle to the previous sketch plane.

Then you'll be able to sketch the 2nd angled pipe on this new plane, thus completing the three-way pipe "skeleton", which you can use it to drive the solids.

It can be done with a single 3d sketch too, if you enjoy 3d trig and/or herding kittens.

I hope this is what you where looking for
I did not know if it was metric or standard
inches or feet

sorry I usually draw using American standard measurements
here it is in metric

No doubt this is one of those examples where everyone will have their own way of creating the part, but there really is not a right, or best answer.

I've attached my version (SolidWorks 2017), along with a step file and image.

I did not bother measuring anything but the angles. I am a bit confused by the angular measurements shown in your left most image. They appear to be measured off the vertical wall of the main pipe, but from the sketch, it appears they should be measured to the horizon.

One other method you could use, is to insert a plane normal to the screen/view.

If you go into the SolidWorks options and set your default arrow rotation increment to say 1°
You can then easily rotate the model to any compound angle with the arrow keys, or arrow keys + Alt (for rotation.
Now insert a reference plane, choose a point as the first reference, then choose the normal to screen option.

Using layout sketches is "better" in my opinion, but shortcuts often lead to the same location in the end.
