How to ADD and REMOVE EDGE LOOPS in Blender

In this arti¬≠cle we see how to add edge loop to a 3D mod¬≠el to obtain extra geom¬≠e¬≠try allow¬≠ing us to increase the detail on our model.

Adding edge loops to a model in Blender

We start with a 3D mod­el like the one shown in fig­ure 1, what we want is to add sub­di­vi­sions to the mesh dis­trib­uted along the cylinder.

Press CTRL+R and move the mouse to the object you want to cut until you see a rep¬≠re¬≠sen¬≠ta¬≠tion of the new edge loop as shown in fig¬≠ure 2, if you left click on that moment you will cre¬≠ate the edge loop, but you can also increase the num¬≠ber of sub¬≠di¬≠vi¬≠sions by turn¬≠ing the mouse wheel, so you get what you see in fig¬≠ure 3, a cer¬≠tain num¬≠ber of edge loops equi¬≠spaced along the model.

When we con­firm and cre­ate the edge loops, the win­dow shown in Fig­ure 4 appears in the low­er left cor­ner of the View­port win­dow, in which we can spec­i­fy the num­ber of slices and oth­er parameters.

How to remove an edge loop in Blender

Now what we are look­ing for is to get rid of some edge loops but keep the shape of the object, we start by select­ing the edge loop we want to remove (lat­er we will see how to remove sev­er­al loops at once). A quick way to select an edge loop is to press ALT and click on the edge that is part of the loop we want to select, fig­ure 5 shows where I clicked and the result of the selection.

To remove those edges with¬≠out leav¬≠ing a hole in the mod¬≠el what we have to do is to dis¬≠solve those edges, so with the edges loop select¬≠ed we press X and choose the option "Dis¬≠solve Edges", this pro¬≠duces the result of fig¬≠ure 7.

When we want to remove mul¬≠ti¬≠ple edges with the pre¬≠vi¬≠ous method prob¬≠lems could arise if adja¬≠cent edges are select¬≠ed, as shown in Fig¬≠ure 8, when try¬≠ing to dis¬≠solve two edge loops that are togeth¬≠er the result is as in Fig¬≠ure 9.

An alter¬≠na¬≠tive is to select edge loops leav¬≠ing an inter¬≠me¬≠di¬≠ate loop uns¬≠e¬≠lect¬≠ed, as shown in Fig¬≠ure 10.

In this way the prob¬≠lem of fig¬≠ure 9 does not occur and the loops can be dis¬≠solved cor¬≠rect¬≠ly, as shown in fig¬≠ure 12.
