How to auto merge faces? i apologize in advance because im sure my question isn't very clear.
Basically when I extend these faces out:
i want this face:
and this face:
To be merged so it would look something like this:
Except i did that manually is there a way to have that happen automatically? Also its probably important to mention that im new to blender, and not very good at explaining. Any help would be appreciated!
Edit: When i say new to blender i mean you might have to explain more than usual.
Use Extrude Manifold tool (instead Extrude) just select front face and move forward with Snap to Vertex ...

... than move it up.

Since faces around becomes non-plannar and internally a triangulation happens in unexpected direction it is better to search for Quads to Triangles operator (that does tris in shorter distance) ...

... or you can use Knife tool to triangulate manually by longer edge.
