Soft 90 degree elbow

micahbley — Thu, 24 Apr 2025 01:57:04 GMT

I am very new to fusion and I am trying to make a soft 90 degree elbow for my vacuum and I am not sure what tools to use I have tried revolving and using a loft but I can’t get it the way I want it.

The easiest method is to use the pipe command. Simply draw an arc to use as the path.

Extrude, Sweep, Loft, and Boundary fill, (before the Mirror), with various Sketches.

Was not able to figure out the rib shape at the centre boss, but you can follow my lead with the other flanges.

Canvas is distorted so internal wall thickness is a fudge. If you wanted constant (stepped - doubt it) wall thickness, use a Shell or Loft > cut instead of my Revolve.

Might help...

If you are planning to print this, think about it carefully.
If you have ever printed a 90° pipe bend, you will know that this is problematic.
It doesn't work without support. The wall will be rough. This means that dirt will accumulate.
If I may give you some advice, save yourself a lot of test prints and buy it for less money.

Here's an example using the Pipe command. The flanges can be added with straight lines as the path for another Pipe command.
