Sometimes, you want to specify the length of a dimension line, rather than drawing it.

Drawing a Manual-Length Dimension Line

To specify a dimension,

• Click on the Dimension button on the Home tab ribbon- bar.
• Click on an Arrow key (Right, Up, Left, or Down) on the keyboard for the general direction that you want the dimension line to go. This opens the Add Line window.
• If you selected the Right arrow key in step three, the Angle field will display as 0. Up would display as 90 degrees, Left as 180 degrees, or Down as 270 degrees. Alternately, you can enter any value between 0 and 360 degrees into the Angle field.
• Click on Ok to draw the dimension line. If you clicked on the Offset point box, then the dimension line will not be drawn; rather, the starting Point will be offset by the Feet, Inch, Fraction value, and you can now press an Arrow key (back to Step 3) to begin the dimension line from the new offset location.

A dimension line specified at 35' 8 and 10 degrees is shown.
