• New
  start a new 2D shape
• Open
  open a saved 2D shape
• Save
  save the current shape to a 2d file
• Rotate 90 Degrees
  rotates the current shape 90 degrees about the origin (green dot)
• Rotate 45 Degrees
  rorates the current shape 45 degrees
• Flip Vertically
  flips the current shape vertically about the origin
• Flip Horizantal
  flips the current shape horizantally about the origin
• Scale Up
  scale the shape up by 50%
• Scale Down
  scale the shape down
• Zoom In
  Go on, guess
• Zoom Out
  Zoom out on the image
• Split Segment
  Add a vertex in the middle of the current selected segment
• Delete
  Delete the seleted vertex
• Linear Segment
  Changes the currently selected segment to a linear (straight) line between 2 points
• Bezier Segment
  Changes the currently selected segment to a bezier line, giving you 2 points to create a stylish curve with.
• Create a Sheet
  creates a flat sheet brush from the current shape
• Create a Revolved Shape
  rotates the shape about the origin. Options for number of segments per 360 degrees, and how many to produce, e.g. if you choose 8 segments per 360 degrees and only draw 4 the shape will only be half of a full rotation. It will be rotated about the green pivot point.
• Create an Extruded Shape
  extrudes the current shape (e.g. a square would make a cube or cuboid)
• Extrude to Point
  Extrudes to a point, come on now work with me... A cube would make a square based pyramid.
  Extrude to Bevel
  Extrudes to a bevel, which is basically a pyramid with a bit chopped off the top. The Depth is the height of the pyramid and the Cap Height is the height from the base. Therefore is Depth and Cap Height are the same then it is effectively Extrude to Point, and if Cap Height is 0 (which it doesn't actually allow) then it is just Create A Sheet.
