I have a cylinder inside another cylinder and i want to remove the surface of the small cylinder in the large cylinder so i get a large cylinder with a hole in it. How can I merge the vertices of the small cylinder to the faces of the large cylinder so I can remove the faces of the small cylinder?

Allready thanks and cheers!

  • $\begingroup$ Please attach a screenshot of your two cylinders and I will do my best to give an answer. Generally, you don't merge a vertex to a face, but there are other solutions, such as extrusion. $\endgroup$ – Gunslinger Jan 6 '14 at 12:42

I'm not entirely sure I understand how you cylinders are aligned towards each other, but it doesn't matter to much. I'm going to use the "bridge two edgeloops" operation.

Here is my starting position:

cylinders in wireframe mode

I edit both of them and remove the end caps.

cylinders without end caps

Then I select them both and join them Ctrl + J. Now I again go into edit mode and select both edgeloops at the end of the cylinders. Hold down Alt to select and edge loop. Hold down Shift + Alt to select the other without deselecting the first.

Then hit space and type "bri" in the menu. It should look like this. Hit Enter

edge loops and bridge command

Now the two edge loops should be bridged with faces:

bridged edges
