The Line Tool 

The Line Tool places a line on your image.  Click on the line tool and drag 'n' drop it onto the screen.  A line will appear on the image viewer.  Click on the line and arrange it the way you want by using the small boxes on either end or in the middle.



Right-click on the line to bring up the LineSegmentEntity edit box, as seen below.  Selecting the Entity tab allows you to adjust the colors, thickness, size, type and visibility of the line.  You can also select a Coordinate System. Make the necessary adjustments, click Apply and then Close.  The values will be updated according to your selections.




Selecting the Line tab allows you to enter values for both X, Y, and Z coordinates.  Make the necessary adjustments, click Apply and then Close.  The line segment will be updated according to the values selected.
