This tool allows you to start a line anywhere on the drawing and have it drawn tangent to any arc or circle on the plan. The modifier panel allows you to enter in the length of the line you want to insert into the drawing.
To use this tool:
1. Click on the tool (shown above) to open the modifier.
2. Enter the length of the line to be drawn (if required) and press the [spacebar].
3. Once the values are entered, click where you want the line to be drawn to begin.
4. Click on the circle/arc that you want the line drawn tangent to. The circle/arc will highlight blue, and a ghost (‘thin’ image of the line) line will be placed on the drawing.
5. To complete the process, click where you wish the line to end.
