Basic Curves

  • Add object (Cube)
  • Add Bezier Curve
  • Select object
    • Add Array modifier
      • Consider using Merge (otherwise there will be segments that appear with Bevel)
    • Add Curve modifier
      • Select the Bezier curve
  • To add more segments: increase array modifier count
  • To refine the curve, subdivide the bezier curve

Mirroring Objects[1]

  • Delete half of your model. You should now have a perfect other half with a planar “hole” where the other half was.
  • Go into Object mode and press Alt+D.
    • This will make a linked duplicate: any changes to the mesh data of one object will be duplicated over the other. Don’t move the object after duplication.
  • Ctrl+M -> X Local.
  • When you’re using Subsurf the derived mesh will not “cross over” between the halves; a seam will be visible. So to join the halves, select both and Ctrl+J. * * * Then Remove Doubles in Edit mode.

Removing Non Manifold

  • Edit Mode -> Select -> All by Trait -> Non Manifold -> DELETE VERTICES [1]

Snap Two Faces Together

Splitting Objects

Down The Middle

  • Good for cubes[2]
  • Select Object
  • CTRL+R and move curse near the axis to be cut, a line should appear
  • LMB and then RMB
  • Change to wireframe view
  • Press 1 for Vertex selection
  • Shift+LMB select the rest of vertices on one half of the object
  • Separate (P), then Selection (2)
  • You have two objects!

Knife

  • Rotate the body so the cut follows an axis (make note of the angle)
  • Edit Mode
  • Knife (K), Cut Through (Z), Constrain Angle (C) <for straight cut>
  • Make the cut line
  • LMB to stop cut
  • Enter to finalize
  • Select -> Select Loop Inner Region
  • Mesh -> Separate -> Selection

Blender Guru

Probably the most useful series that I found was by Blender Guru. He's patient and walks through the items. Do the tutorial bits, they are handy. He has a handy PDF (you have to sign up to get it) for shortcuts.
