I remember blender being pretty easy to use. For some reason I keep running into problems. For example:

  1. Create a circle mesh with no faces.

  2. Cut off half the vertices and connect the two ends to make a half circle.

  3. Scale it up and apply the scaling. (Don't know if it matters, but I'm using imperial units.) The faces appear odd, which turns out to be because the faces have been doubled. I fix this by removing doubles and recalculating normals.

  4. Extend the edges down and fill in the top, ending up with a semi-circle platform looking thing.

  5. Do a loop select on the side faces and deselect the rear diameter face. One of the adjacent faces is also deselected. I decided to try deleting the seemingly connected face and recreate it. However, when I try to select ONLY the lower two vertices, all four vertices are selected like so:

    Did you select those 2 lower vertices with Ctrl ? It's the only way I can think of to select 4 vertices in this case. This would mean selecting a loop of 4 vertices. – Mr Zak Jan 23 '16 at 20:02
  • I did select them with Ctrl. I thought that was the correct way of selecting multiple vertices. – AaronF Jan 26 '16 at 14:54
  • Not quite. As I wrote If you select with Ctrl this means you select vertex loop (in this case vertex loop because you are in Vertex Selection mode). To just select several vertices press Shift. See Basic selection in wiki – Mr Zak Jan 26 '16 at 15:04
  • Yeah, my bad. Used to use it all the time. I guess I just got rusty. – AaronF Jan 26 '16 at 15:23
  • Shift toggles the selection of an individual vertex. Ctrl selects the vertices on the shortest path between previously selected vertices and the one you are clicking. Alt selects a vertex loop. – Robin Betts Mar 31 at 10:36

Seems like by you step 3 goes wrong somehow. I've scaled the shape with no issues and all worked smoothly afterwards. But I use metric units :) May be it really matters

    The faces won't be neither doubled nor pointed in the wrong way only because of another unit system used. They could be pointed wrong because of direction in which extrusion was made though. – Mr Zak Jan 23 '16 at 20:16
  • Yeah. I know the units shouldn't matter. I just put in every detail I could think of. Can you post a blend file on here? – AaronF Jan 23 '16 at 22:12
  • Well, I can't duplicate the bug. If I ever do again, I'll post the file. Sorry for the trouble. – AaronF Jan 23 '16 at 22:14
  • There might be something gone wrong earlier, since there should be no double faces when extracting a single loop of vertices. – metaphor_set Jul 22 '16 at 16:01
