Follow the below instructions for various distance techniques.

Measuring Distance Along a Straight Line  
The Distance Tool enables you to calculate distance from a specific start point to a specific stop point on an image. You can use the Distance Tool to measure straight lines, free form lines, and to calculate cumulative distances.  
To measure distance along a straight line:  
1.Select the Distance tool.  
2.Click a starting point on the image, hold down the mouse button, and drag to the ending point.  
3.Release the mouse button.  
 
Measuring Distance Along a Free form Line  
The Distance Tool enables you to measure distances even when the path does not fall along a straight line.  
To measure distance along a free form line:  
1.Select the Distance tool.  
2.Click a starting point and hold down the ALT key while you drag the mouse. You will be able to draw a line of any shape, not just a straight line. Distance is measured along the path the mouse travels.  
3.Release the mouse button.  

Measuring an Intermediate Distance Along a Straight Line  
The Distance Tool enables you to measure distances without releasing the mouse button.  
To measure intermediate distance along a straight line:  
1.Select the Distance tool.  
2.Click a starting point on the image, hold down the mouse button, and drag to an intermediate point.  
3.Press and release the Shift key.  
4.Drag to another intermediate point and repeat Step 3.  
5.Repeat Step 4 as needed.  
6.Release the mouse button.  

Measuring the Cumulative Distance along Line Segments  
The Distance Tool enables you to measure the cumulative distance along multiple line segments.  
To measure cumulative distance along multiple line segments:  
1.Select the Distance tool.  
2.Click a starting point on the image, hold down the mouse button, and drag out the first line segment.  
3.Press and release the v key. This drop a vertex at this point.  
4.Drag to out another line segment in any direction and repeat Step 3.  
5.Repeat Step 4 as needed.  
6.Release the mouse button.  

Measuring Perimeter  
The Distance Tool enables you to measure the distance around the outside edge of an object. You can measure the perimeter of a square or rectangle using a parallelogram. You can measure the perimeter of a free form shape using a free form line.  
To measure perimeter using a parallelogram:  
1.Select the Distance tool.  
2.Click a starting point and draw a straight line along the edge of an object.  
3.Press the CTRL key and drag the mouse along the adjoining edge of the object. The tool creates a boxed line around the perimeter of the object.  
4.Release the mouse button.  

To measure perimeter using a free form line:  
1.Select the Distance tool.  
2.Click a starting point and hold down the ALT key while you draw a line around the outside of the object. For the best results, ensure that the start point and stop point are joined.  
3.Release the mouse button.  


To measure height, click clip0031. The height measurement will be shown in a message box.

Measuring Height  
The Height Tool enables you to measure the height of an object in an oblique image.  
To measure the height of an object:  
1.Select the Height tool.  
2.Select a starting point at the base of an object (such as the base of a building), hold down the mouse button, and drag to the ending point.  
3.Release the mouse button.
