A few questions.

  1. How do i delete a vertex? For example, to turn a square plane into a triangle. Can I join two vertices(Or edges or sides, for that matter) together into one, joining two objects?

  2. I did something by accident, but I’m not sure what. Suddenly all my objects weren’t transparent anymore, and I couldn’t select anything. No faces, edges, etc. What did I do, and how do I reverse it?

  3. I have whole meshes/objects selected when I add them,
    but I can’t reselect them unless I manually select all edges, faces, or each vertex. Why is this, And is there any way to select whole objects again? It simply won’t let me anymore.

  4. Instead of using the rotate tool, is it possible to type in a number(Degrees) and set my object’s angle that way?

You can delete a vertex by selecting it and then pressing X. You can also select multiple vertices and join them with Alt-M.

    You most likely hit Z, which switches between wireframe and solid. It might’ve also been Tab which switches between (mesh) Edit Mode and Object Mode.

    I believe you’re adding them all as part of the same Object. Use Tab to switch back out of Edit Mode and into Object Mode to add new objects separately. You can also, in Edit Mode, select all connected verts with L (or Ctrl-L, I get confused sometimes).

    Yep. When you start to rotate, just type in the number and it will rotate that many degrees instead of using your mouse input. This technique works with all of the transform tools.

I highly recommend reading the user’s manual, which you can find at http://wiki.blender.org/index.php/Manual

Thanks for the help!

But…as far as I can recall, pressing x with a vertex selected brings up a small menu, including
Edges
Vertices
Faces
All
Edges and faces

And a couple others. I click vertices and it deletes all vertices in the object instead of just the one I have selected.

As for joining the vertices, will the one vertex they all end up as just snap to the middle of where the vertices were? As in…the average location?

Yes, X does bring up a menu, however chosing Vertices will only delete those vertices which are selected at the time you pressed it. I promise. That’s really how it works. :slight_smile:

The only hitch is that it might delete more than you expect if you’re in Edge or Face select mode (Ctrl-Tab).

As for joining, it also offers you a menu that gives you a couple options, including At Center, At First and At Last.
