Too many vertices? Is it my Blender-version?

[SeventhWave]

I tried to follow the tutorial very diligently, but when I try to give the roof of the house a curve by grabbing the two vertices of the roof (that were created with the loop cut) and dragging down, I see more edges than expected (see image).

Now I used extrude to make the roof, like the instructor did, so it’s possible that made more vertices, but this is not discussed in the video at this point. Or did I miss something?

I can work around it by using proportional editing, but in the video, the instructor is not using that.

Am I doing something different from the instructor, or is my Blender version (3.0.1) different in this way than the one in the video?

With proportional editing:

Classic double geometry.
Extrude does not cancel the extra geometry creation if you escape out of it.

Select all. Press M and choose by distance and it should merge away the extra verts.

Always gets me. Thank you. I will try it and see if it works… earlier I used merge->center but that got real weird real quick.

I tried to reproduce it by deleting the new roof and the loop cuts, but I am not really getting it yet.

I can’t tell whether I have selected the multiples. It doesn’t LOOK like it, and box select is mysteriously not working (in edit mode).

When I try to merge by distance, all I see is:

I am not entirely sure how to solve this.

Wait, never mind, problem exists between desk chair and keyboard!

I forgot to use select all. I selected only the one edge.

Now I think I got it. The menu mentioned removing 8 vertices and the grab function works as described now. Thanks a bunch! I did some modelling before and this stymied me then, too!

If you press e to extrude, the extrusion already took place and Blender is automatically waiting for the user to move the extruded part. If you don’t do that or cancel the action (ESC), then you have vertex duplication and problems ahead.
