Principles

A report is sent automatically to the Request region each time you run a clash check; that is, each time you enter a CHECK, BOXCHECK or CHECKADD command. You can change the format for such a report before running the clash check if necessary. In addition, you may send output to a file by using the ALPHA FILE or ALPHA LOG commands in the usual way.

The default report format comprises the following three parts:

• The report header: Details of the program version in use; the types of clash reported; any non-default checking options and limits; the touch and clearance limits; any special reporting options in use.

• The main body: Details of the clashes found, including the clash type and extent and the identifiers of the two design items involved. The clashes are grouped into sections, one for each significant element that contains an interference. Where space permits, each clash is reported on a single line.

• The clash summary: Lists the total number of clashes of each type found; the total number of elements checked during the run covered by the report; the number of elements found to be free of any interferences.

All data resulting from a clash-checking run is held in the computer’s memory until overwritten by data from a later run (or until you change modules). This allows you to generate further reports derived from the same data, possibly using different reporting options from those in force for the original report.
