Clash Recomputation Form

Recomputation is an Administrator Configuration task that becomes necessary when the values of significant attributes in the model have been changed, for example, if discipline codes are changed. This is because these changes to the model are not automatically communicated back to the Clash Manager, unless the relevant clash sets are rerun, or the recomputation process is initiated at this form.

The changes to the model can have been made independently in PDMS, or in Clash Manager at the 'Clash Manager Configuration' form. Following changes made in PDMS, the Recomputation form must be accessed manually. When significant items are modified at the Clash Manager Configuration form, the Recomputation form is displayed automatically with the appropriate default entries in the relevant check boxes. Examples of the changes that cause automatic display of the form are:

•

rules added or deleted

•

regular expressions modified

•

defaults changed

•

defined attributes changed.

Note:

When the recomputation process is performed, it is usually necessary to preserve the current approval status, in spite of any change in Acceptance Rules that would subsequently lead to different results. Also, it should be noted that Rules are applied only when a clash is initially discovered; subsequent manual settings of attributes usually need to be preserved. Clash acceptance can be excluded from the process, as can any other aspects, by appropriate entries at this form.

The form contains the following items:


Element Properties block containing:
Class, Priority, Discipline, MMSDESCRIPTION	The states are referred to here as 'checked', 'checked shaded', and 'blank'.
	.The checkbox titles are the default values of project-defined fields that can be set at the Clash Manager Configuration form. The fields are used for selecting attributes, the values of which are to be copied verbatim into the Clash Manager database for reporting purposes and use for filtering etc. Areacode (and others) are defined on the Project tab of the form. Class and Priority and Discipline have their own tabs. The checkbox titles show the default values and/or those of the attribute(s) set by the user.
	When 'checked', the value of the particular attribute is unconditionally recomputed for every element. The phrase Recompute ALL appears before the checkbox title.
	When 'checked shaded', the value of the particular attribute is only recomputed for elements where the attribute is currently UNSET. The phrase Recompute only unset appears before the checkbox title name. When 'blank'', the attribute is not affected by the recompute process.


Clash Properties block containing:
Five checkboxes at the left-hand side of the block. (Checking a checkbox enables recomputation of the associated property. When the checkbox is blank, the property is not affected by the recomputation process)
Group Ownership of Clash Details	When the checkbox is checked, Clash Group Ownership is recomputed for every clash detail.
Clash Assignment (Discipline Owner)	When the 'ALL' option is selected at the drop-down list, the discipline ownership is recomputed for every clash detail. When a discipline is selected, the ownership is recomputed for clash details for that discipline only.
Clash Acceptance (Clash Status)	When the 'ALL' option is selected at the drop-down list, the clash acceptance status is recomputed for every clash detail. When a status is selected, the clash acceptance status is recomputed for clash details where the status is currently the one selected.
Clash Group worst case Level/Type	When the checkbox is checked, the Clash Group worst case Level/Type is recomputed for every clash detail
Clash Group Status from details	When the checkbox is checked, the status of each active clash group is reset to the value of the worst case status of any of its member clash details. This option is provided for cases where clash detail status has been set by hand and the group status consequently may be out-of-date.
Caution: If any group status has been set by hand, and 'Apply Group changes to Clash Details' on the 'Clash Manager Options' form has been set to False, the member details status will not necessarily match the group status. Therefore, recomputation using the 'Clash Group Status from details' option could change the Clash Group status to that of the worst case member clash detail.
Checkboxes at the lower right-hand side of the block
Remove 'User Modified' Flag and Recompute Manually set items	When the checkbox is checked, all Manual Flags (see Note on Auto Rules checkboxes) are unset and, in future, all clashes are treated as though their details had been set automatically.


Progress bar	Indicates the percentage completion of the recomputation process
OK	Initiates the recomputation process
Reset	Restores the recently changed settings made at the Clash Manager Options form
Cancel	Cancels the selections made and closes the form
