so many good tricks in this video. Good pacing with quick "do this because X. Do this because Y. Do this because Z" mentality. Nothing unneeded in this one!
When I use this same procedure and then export to an stl file for 3D printing, the elbow section does not look smooth at all. But if I use a portion of a torus as the elbow section then the 3D print looks very smooth. Do you know perhaps why this is?
This was good. But, very crude and not accurate for use. The pipe dimensions for use, if arms/legs were required to be 200mm, then you can not tack the 10 mm for the flange thickness on each leg. You'd have to make the flange ID to the pipe OD and have a different weld and grinding then what was shown. It is also easier to weld at the end of the pipe than inside the pipe. So, the flange is best to be made with its ID to the OD of the pipe and slipped onto the pipe. Then, welded in place. Sorry ----- real world issue. Not just make a pretty 3D picture. And not forget the orientation of the hole pattern. What would the real clocking need to be for the 8 hole pattern. Tip: Hole patterns are always the elephant in the room. When it comes to manufacturing. Always the biggest headaches.
Sorry you see this as crude, its called parametric modeling and you as a designer determines the accuracy and form of your part depending on your manufacturing requirements. All the geometry that was created in this example was produced by rules and parameters (in FreeCAD we call these Constraints). For example the inner radius of the Flange and the outer diameter of the pipe is 50mm. If you want the pipe to slip into the flange , you have 2 option you reduce the pipe outer diameter or you increase the inner radius of the flange to allow the pipe to go through the flange (depends on your tolerances and design goals). Please note that welding, 3D printing and CNC requirements can call for different design approaches and you as the designer determines which approach fits your manufacturing technology. Thanks

Very Clean, Clear and Concise 👌👌

Excellent tutorial. Also, a good example of using Freecad's local coordinate system.
Excellent tutorial, great great. Keep posting videos
I had been looking for how to make a pipe elbow. Thanks for the video! Subscribed.
Glad that it helped !
So good. Thank you
How would you change the length of the pipe on each side of the elbow?
Thank you.

Danke...Thank You :)
Did work once, and then I'm getting some error while trying to do the thickness part: brep_api command not done
This example was made using version 0.19. Please make sure you are using the same version as some examples may not work in different versions
Good Video! But there are probably several ways to reuse the first flange.
Great point! Yes that's true and depends on the workbench you are working in ; Part , PartDesign, Draft etc.
nice one
Thanks
