About Creating a New Check from Two or More Checks
You can use the outcome of two or more checks to create a new check. A situation in which a new check is useful is described as follows:
The total number of features reported by the REG_FEATURES check can divide the number of datum planes reported by the DTM_PLANE_INFO check. The results can be reported as Number of datum planes as a percentage of all features and a threshold can be set where an error is reported if the number goes over 25 percent.
The new check is listed in the check configuration file using the following syntax:
[CHK]_[user_defined_name]_[check_mode] YNEW E E E E Y
Where:
• CHK specifies that it is a custom check.
• user_defined_name is the user-defined and case-sensitive name of the check.
• check_mode is the mode in which the check is to be run. The mode can be PRT, DRW, or ASM.
The check definition is stored in a separate file and is specified in the start configuration file as follows:
CUSTOM_CHECKS_FILE custom_check.txt
The file can be named whatever you like. In this instance it is called custom_check.txt. If no path is given, the file is assumed to be in the config directory.
