I have an edge loop that is part of the same object as the box shown below. I would like to merge it into the face that it is on top of to make the geometry all one.

  • $\begingroup$ For creating the rounded square you see, I created a circle and delete it some verticles, but the circle isn't connected to the main mesh, even if it's in the same object, i'm stuck at this point :/ $\endgroup$ – Tom Dafunk Aug 26 '16 at 18:15
  • $\begingroup$ See my answer. It has more details. $\endgroup$ – Shady Puck Aug 26 '16 at 18:31
  • $\begingroup$ i'm sorry but cegaton saved my life this time :/ (and i know how to use the knife) thank you for the effort you made. $\endgroup$ – Tom Dafunk Aug 26 '16 at 18:58

If the two edge loops have the same number of vertices you can use bridge edge loops.

Delete the face that connects the outside loop.

Select all and do: Bridge Edge Loops

enter image description here

  • $\begingroup$ FYI, the Bridge tool doesn't require an equal number of verts on both edges. $\endgroup$ – Anthony Forwood Aug 26 '16 at 19:48
  • $\begingroup$ Nice! But I tried your tip, but the result was awful, double face overlapping... etc... so I made it myself face by face and the result is more than satisfying! i.imgur.com/6IjMro1.png $\endgroup$ – Tom Dafunk Aug 26 '16 at 20:52

Knife Project

If the vertices and box are two separate objects, great! If not, select one vertex of the edge loop, key Ctrl + L to Select Linked, key P to open the Separate menu, and select By Selection.

Move the loop away from the object on the Y-Axis a bit. Key Numpad 5 to enter Orthographic View. Key most likely either Numpad 3 or Ctrl + Numpad 3 (whatever view shows the loop in front of the box).

Select the edge loop, then the box, then key Tab to enter Edit Mode for the box. Select the one face you wanted to add the vertices to, key Ctrl + I to Select Inverse, and key H to hide the other faces. Key Space, type Knife Project, and key Enter. Key Alt + H to reveal the other faces.
