How to Make Smooth Bevel Curve Without Extra Crease?

Question

I want to make something like a curve-shape pipe, so I use curve (I make an edge and convert it to curve because I need it like that in original work) and bevel it with bevel>object> beziercircle and it looks like that:

After that I convert it to mesh, and do bevel of the angle edge loop in the middle

But it look like that:

So how can I make it even and smooth without these crease that indicated by red arrows? I add subdivision modifier and auto-smooth but it still the same.

Answer 1

Maybe put an additional edge loop close to it, it should attenuate the problem:

If you ever want an alternative that works (but the whole profile is different so it may not be what you want):

Create your pipe with a series of vertices, when you want to curve an angle, bevel the vertex:

Convert to curve, go in the Properties panel > Object Data > Geometry, and bevel:

Answer 2

I like simple solutions, so here's my take on the problem

1.Enable the Add Mesh: Extra Objects add-on in preferences if not already enabled (it is bundled with Blender by default)

2.Shift+A >mesh>Pipe Joints> Pipe Elbow

3.In the redo panel (F9 in default 2.8x keymap) change the angle as desired

4.Add Subdivision Surface Modifier

Note, if curves are an absolute necessity at some point after this, you can always convert this mesh (or a copy of it) to a curve.

Answer 3

Personally I'd start with a cylinder, select the vertices round one end and then use the Spin tool to extrude round the cursor. Details From the Blender manual or a YouTube video.
