Clash Manager User Guide

Branch Check Type	Used to select either 'A Check' or 'B Check' for this run. The default is set in the data associated with the Clash Set. 'A Check' does a full primitive by primitive check of every component within a branch. This option is not normally recommended. 'B Check' is a simplified check which ignores clashes between certain pairs of components within the branches. This option is normally used.
MAP Override	If checked, causes desclash to ignore errors in the Spatial Map, which would otherwise abort the desclash run. The default is given in the Clash Set data.
Check ADD	Passes the ‘Check ADD’ option to desclash. This causes the Clash Check List to be automatically added to the Obstruction List. Any existing contents of the Obstruction List are ignored. The default is given in the Clash Set data.
Ignore Connections	Ignore Connections at steelwork Junctions. The default is given in the Clash Set data.
Modified Checklist Items Only	Sets the date of the last run of the selected Clash Set and each check-item tested for a change in GEOMetry since that date. Items that have changed or that have not been checked before will be checked as usual. Items that have not changed will be recorded and any previously found clashes will be recovered and incorporated into the current clash run.
Clash Run Comments	Allows the user to enter comments prior to the clash run.
Progress bar and adjacent indications	During the clash run, the bar graphically indicates the percentage progress. During the clash run, a 'Loading item number' message appears above the bar and is continually updated. During the clash run, continually updated numbers below the bar show 'Total clashes processed' and a 'Significant Elements'. During the clash run, a 'Heartbeat' at the bottom right-hand of the form shows that the process is in operation. If the clash update cannot be completed, an error message appears.
