When I posted my paper airplane, I meant to ask a question about rotation. To get the results I expected when rotating a section of the plane in the vertex modeller, I had to rotate and move the entire model so that the edges I wanted to rotate lined up with 0 on one of the main x/y/z axis, select that section, do the rotation I wanted, then select the whole model and put it back where it was when I started. For example, I started by putting in edges where all the folds go, and positionin my model so that the nose was at 0,0,0 (which I verified by selecting that point and looking at properties -- I do a lot of my modeling by typing in the values I want). To fold down the first corner, I then rotate the whole plane 45 degrees so that the fold I wanted to make lined up on the y axis. I selected the corner I wanted to rotate, rotated it (90 degrees in this case), then selected the whole plane and rotated it -45 degrees to get it in the original position. Now, before Carrara I used POV-Ray, and this was basically how you had to rotate stuff; everything rotated relative to the origin. It seems to work the same way in the vertex modeller. So, am I doing this the right way, or is there a short cut? Sorry for the long post.
