Loop cut entirely after dissolving an edge I can still cut it entirely with the Loop cut.



Thing is, I want to get rid of that edge, I do that by dissolving it:



Now here's the problem, after that, I can't cut it entirely. I've also tried dissolving the remaining vertices but it didn't work.



So what I want to do is to cut it entirely after dissolving the edge, instead of doing it separately as you can see in the pic. Is there a way to achieve that? Did I make a wrong move?
You can not use the Loop Cut tool because you have an n-gon (face with more than 4 vertices, in your case 5) on the top.

The Loop Cut tool only works with quads (faces with 4 vertices).

First use Dissolve Edges then immediately after use Dissolve Vertices; Or update to the newest version and use Dissolve Edges and Vertices.
