Creating a Line from Start Point to End Point

To create a single line from its start point to its end point:

  1. Click the Line tool from the Basic palette.

  2. Click either the Constrained or Unconstrained mode.

  3. To scale the line as you draw it, click Preferences from the Tool bar, and enter the scale factor (must be larger than zero). The created line will be the length of the line you draw multiplied by this number. For example, enter 2 to create a line twice as long as the drawn line, or enter 0.5 to create a line half as long as the drawn line. By default, the value is 1, which does not affect the line length.

  4. Click Vertex mode.

  5. Click at the line’s start point.

  6. Click again to set the end point of the line. If you entered a scale factor other than 1, the length of the finished line is adjusted accordingly.
