I'm trying to join these two cylinders together. I tried the pipe joint mesh but the diameter will not go small enough.

Equally, is there is a way to extrude the face of the top cylinder vertically downwards at an angle but that the face is level?

I am new to Blender so realise this seems very simple but any help would be appreciated!

  • $\begingroup$ you can activate the LoopTools addon if it's not already the case, then select the two edges and right click > LoopTools > Bridge $\endgroup$ – moonboots Jun 19 '20 at 9:17

  • $\begingroup$ yes, but it looks like it is not available in Vertex Selection mode (in my 2.8 version at least)? Not sure why... $\endgroup$ – moonboots Jun 19 '20 at 10:24

    $\begingroup$ it's not clear if you want a round transition between your 2 cylinders or you want to keep a sharp angle? $\endgroup$ – moonboots Jun 19 '20 at 12:51

To make a pipe bend the quickest way is to use the Bridge tool: Select both the 2 rims vertices and right click (context menu) > LoopTools > Bridge (you may need to activate the LoopTools addon before), or in Edge Select mode, CtrlE > Bridge Edge Loops. Then in the Operator box, set the bend as you want.

enter image description here

If you want to create a pipe bend but want to keep a sharp edge, the new (2.8) Mirror modifier allows you to do it easily: Create your cylinder, create an empty, give your cylinder a Mirror modifier with the empty as Mirror Object, choose (in my case) Axis > X, Bisect > X, Flip > X, move and rotate the empty until the cylinder and its mirrored merge the way you want (keep pressing Ctrl during the rotation if you want it to be 10° by 10°).

The Shear tool also allows you to create sharp bends but it's not convenient if you want precise angles or if your object is not perpendicular to the axis.

Select the top loop of vertices on the bottom section and the bottom loop on the. Upper section,

Press F3 and type bridge edge loops and play with the offset.

Or enable the Mesh extra objects add-on.

Then you can create the object directly by adding add pipe joints and choose the shape kind. Of pipes you need

  • $\begingroup$ Yes, I tried this at first but then realised it has a minimum radius of 1cm and my design is smaller than that. But the bridge edge loops worked so all fixed! $\endgroup$ – Aylor Jun 19 '20 at 15:50
