2.4.1  Draw Toolbox:

         The Draw toolbox is displayed by default when you enter the Sketching mode. Use the tools to draw 2D
         edges and apply dimensions and constraints.




































         Line:  Use the cursor to indicate a start and end for the line.
         Tangent Line:  To maintain tangency between a line and an edge, use the Tangent Line tool. Click on an
         existing edge or endpoint to start the line. It will rubber band as tangent to the selected edge and you
         can then indicate the length of the line.
         Line by 2 Tangents: To create a line tangent to two edges (or points), use the Line by 2 Tangents tool.
         Select two edges or points near the desired tangent location on each edge. The defined line will start
         and end at the tangency location on each selection.
         Polyline:  To draw a closed or open polygon, use the Polyline tool. The Polyline tool allows you to draw
         a series of connected lines. You need to use one of the right mouse button options, Open End or Closed
         End, to finish your input and actually define the lines.
         Rectangle:  To  proportionately  draw  a  rectangle  with  a  horizontal/vertical  orientation,  use  the
         Rectangle tool. It allows you to draw a horizontal and vertical oriented rectangle (defined by four
         edges), by indicating opposite corners.
