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.
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.
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.
