I'm learning Blender and i face this issue that i can't figure out:

I have this isometric shape:

I was trying to move this face on red x-axis:
moving face

And this what happened, actually this is what i want to do , it's kind of a mix between extrude and move:
the right move

But when i tried to do the same thing to the left side, this is what happened, it's moving all the connected faces as well:
the problem

I noticed that if i merge all vertices by distance i cant move the face as i wanted anymore.

This is how the face looks when moving it before i merged the vertices "what i want".
before i merged vertices

Is there any way around this, or a un-merge vertices option!


Edit :

This is what i'm trying to do, if you have good method to model it:


This way still has some issues , I know I can fill missing edges but later on I might be missing lot of faces :


  • $\begingroup$ have extruded the second face you're talking about? It looks like not. Also, it's not the good way to model your wall, because you'll have the face of the bottom of your extrusion that will stick to the face underneath. You need to create an edge on the base wall... $\endgroup$ – moonboots May 12 '20 at 6:48
  • $\begingroup$ I did not use extrude at all for both sides . i only selected the face and moved it along axis. you are right its not good way .. i found out that i cant merge the face underneath the wall with other faces, i thought there is a way to remove it automatically. now im stuck . what im trying to do is making this wall look like a "winner stand" 3 level of height. $\endgroup$ – MTriple May 12 '20 at 8:18
  • $\begingroup$ you did extrude the first face $\endgroup$ – moonboots May 12 '20 at 8:32
  • $\begingroup$ i added a cube and used the bevel tool. then i inserted a face and extruded it down 1 meter to create the small wall. i used extrude up on the angular wall which gave me the both side that im moving. for some reason one side has all vertices connected and other is not !! $\endgroup$ – MTriple May 12 '20 at 9:00

In the top bar there will be two orientation parameters when you click the MOVE tool. The first should be "default", make the second one "Normal" from the drop down menu. Move your face now in the desired direction.

  • $\begingroup$ I tried, and I found that it only controls the direction of the move tool. what I m trying to do is split edge and extrude the face then rejoin them and remove doubles. that was the plan. but even with more search and videos i cant understand how to create simple building. i m new to blender, can you please confirm these blender limitation that i found after long search : - cant remove overlapping faces with different length. - cant cut single face by a distance from a vertices or edge. - cant intersect an edge with a face. $\endgroup$ – MTriple May 12 '20 at 10:06

Just add more edge loop where you want to extrude .
