I am cleaning up a friend's model and often run into this problem: Often, there are multiple edges of various lengths overlapping along the same line. Below is a visual example:
A picture of three lines/edges of different lengths. ...that overlap to cause: A picture of four vertices in a line, with darker portions representing overlapping edges. ...as opposed to the desired: A picture of four vertices in a line, with a lack of darker portions representing the lack of overlapping edges. I was wondering if there was an easy way to clean up edges like this without manually deleting the offending edges and reconnecting the relevant vertices?

  • $\begingroup$ I agree that redoing the mesh might be best. Overlapping edges like this often result from depthless extrusions (right-clicking after applying an extrusion, which doesn't cancel the operation) or repeated boolean operations without cleaning the result (merging vertices, deleting unwanted components). You can kindly remind your friend about these hazards and how to avoid them. $\endgroup$ – hatinacat2000 Jun 3 '19 at 2:32
  • $\begingroup$ Use dissolve edges... but poorly planned topology (like the mess that you have in front of you) often takes so much more time and effort than doing it over. Look into retopo workflows using shinkwrap and other available tools (... use your favorite search engine for those). You should aim to re-do this using quads and avoid non-planar faces. Topology is not a wrapper to put on top of the object. Topology is your object. $\endgroup$ – user1853 Jun 3 '19 at 2:58

Check this video, it may help:



Select all the vertices in edit mode and then

v2.79 and below

click spacebar in viewport and type in "Remove Doubles" in the search.


click F3 in viewport and type in "Merge by distance" in the search.


You can use this software called "Instant Mesh" by wjakob by loading the exported mesh file into this software and get a clean mesh.

Hope this helps you!
