Use parameters to specify the point symbol scale or rotation value using the raw description for the point when a point matches a description key.
Parameters are elements that are included in the raw description for a point. For example, the raw description TREE OAK 7 consists of a leading element, TREE, followed by two parameters, OAK and 7, separated by spaces.
Specifying Scale Using a Parameter
If you want the point symbol scale to be read from the raw description for the point when a description key match is found, use the scale parameter property. In the previous example, OAK is parameter 1, and 7 is parameter 2. If you wanted the description key to take the symbol scale value from the second parameter (7) you would specify Parameter 2 as the scale parameter.
For a complete description of all the options available for scaling a point symbol using a description key, see the Description Key Editor.
Specifying Rotation Using a Parameter
If you want the point symbol rotation to be read from the raw description for the point when a description key match is found, use the rotate parameter property. For example, a raw description Hyd 45 A consists of the leading element Hyd followed by two parameters: 45 is parameter 1, and A is parameter 2. If you wanted the description key to use 45 to rotate the point symbol, you would specify parameter 1 as the rotate parameter.
For a complete description of all the options available for rotating a point symbol using a description key, see the Description Key Editor.
You can also use parameters in the raw description to create a full description by using a description key format. For more information, see Description Key Format.
