Blender v2.79.


Let's say I have to extrude all faces of this planar construction containing two edges not included in faces, and one isolated vertex:

enter image description here

In this object, there are not hidden vertices, edges or faces:

enter image description here


If I select all faces in Face-Select mode, the result (after extrusion of the selection) is this one:

enter image description here

The orphan edges have been selected, which isn't what I expected since it is not possible to select the edges manually (e.g. by using Border-Select) in this mode. Looks like a bug to me.


But if I select all edges in Edge-Select mode, then switch to Face-Select mode, the result is this one:

enter image description here

The edges are not kept selected. This behavior seems compliant to the documentation about Select modes:

When switching modes in an “ascendant” way [...] the selected parts will still be selected if they form a complete element in the new mode.


Another strange result: Select All in Vertex-Select mode, switch to Face-Select and back to Vertex-Select:

enter image description here

Only one edge is kept selected as well as the isolated vertex. Seems completely buggy.


Anybody with a clear view of this? What is the correct way to select all complete faces for the extrusion?

    $\begingroup$ There is probably a zero sized face there with overlapping vertex. Try removing doubles $\endgroup$

  • $\begingroup$ @DuarteFarrajotaRamos: I've updated the question, adding the number of faces reported by Blender. Nothing is hidden or co-located (the object is a plane where some faces and edges have been removed). $\endgroup$

  • $\begingroup$ Do you have a file to take a look at? As it stands, I would say select one element, no matter whether it is a Vert, Edge or Face and Select Linked by pressing L with your mouse over your target or Ctrl + L if you are elsewhere. $\endgroup$

I'm not sure why the isolated vertex still gets selected when you come back in Vertex select mode but there may be a good reason for it since that behavior is kept on the new versions of Blender.

But there is a way to select all the faces without selecting isolated edges or vertices and it's Select Faces by Sides (Faces by sides in newer versions) :

enter image description here

It will select all the 4 sided faces by default but you have options for it after you click :

enter image description here

You can change the number of vertices to 3 and change the type to Greater than if you want to select all the faces including n-gons. This will only select faces with 4 vertices and more. If you want to also select triangles, you redo that process once with options set to Greater than 3 and redo it again with Equal to 3.

If you do this in face select mode, you will have all the faces but not isolated edges and vertices.
