Clash Manager User Guide

GUI : Options Form

This form consists of two tabs called Preferences and Advanced. Below the tabs are OK and Cancel buttons for respectively implementing or ignoring any changes made.

Preferences Tab

The Preferences tab enables users to set their preferred method of handling clash information and highlighting features in the Clash report and in the display.

The pane at the left-hand side of the tab enables the following methods of handling clash information to be chosen from a list, selected (true), or deselected (false):

Apply Group changes to Clash Detail

True/False

Updates relevant data in Clash Detail report when changes are made to Clash Groups.

Note:

Depending on the policy selected for the project at the Clash Manager Configuration form, the options of the drop-down list may be restricted to either True or False. If the user is free to choose, both options are available.

Caution: It is recommended that this option is set to True. If it is set to False, clash recomputation with the 'Clash Group Status from details' option selected (see Clash Recomputation form) may reset the status of all clash groups to the status of their worst case clash details.

Enable Quick Assign Keys
1/2 & U/P/C/A

True/False

Enables shortcut keys to be used:
1 - to set Owner Discipline to Discipline of First element
2 - to set Owner Discipline to Discipline of Second element
U - to set clash status to Unapproved
P - to set clash status to Pending
C - to set clash status to Conditional
A - to set clash status to Approved.

Enable 3D View Representation

True/False

Enables or disables highlighting of clashing elements in PDMS

Auto View

True/False

Auto Reset Limits

None

No Limits set for the graphics display

Drawlist

Limits of the graphics display are set to the Drawlist

Selected

Limits of the graphics display are set to the volume enclosed by the Elements referenced in the Selected Clashes

Auto Rotate Origin

True/False

Sets the rotation origin of the graphics display to the clash position (if one clash is selected) or the centre of Elements referenced in the selected clashes (when more than one clash is selected)

Auto Clear 3D Display

True/False

Clears the graphics display before adding elements to drawlist

Auto Display Clash Detail

True/False

Selecting a Group record automatically populates the related Clash Detail under Clash Detail pane (if displayed)

Chart History Count

Select ALL
or number

Sets the number of previous milestones to be included in the statistical display on the Clash Manager form when clash history is selected.

Clash Check CE (leading to
Display Report and Retain
Filter options)

Display Report

When set to True, the clash reports, both group and detail, are automatically displayed after a Clash Check CE process.

Retain Filter

When set to True, the Clash Check CE reports are filtered using a temporary filter that includes ALL filter options, with the Element Name filter set to the appropriate Group Element of the Current Element.

When set to False, the filter is disregarded.

Large Transactions
(leading to Warnings and Worst Case Update Threshold options)

Warnings (record
counts...)
(leads to further options
see next column)

Clash Details from Selected Groups (default 1000)
3D View from Selected Groups (default 10)
Claim/Flush/Issue/Edit/Select All (default 100)
(See Large Transactions below.)

Worst Case Update
Threshold (default 100)

(See Worst Case Update Threshold below.)

Large Transactions

The Warning options enable the user to set the values of record counts that determine when the 'Clash Manager - Large Transaction' dialog box is displayed. This dialog box warns the user that there will be a delay because a large number of records are about to be displayed and/or a large number of operations are about to be performed, and requests confirmation or cancellation of the operation. Details of the record counts are as follows:

Clash Details from Selected Groups - this operates when Auto Display Clash Detail has been selected, clash details are being viewed and the total number of clash groups selected exceeds the set value.

3D View from Selected Groups - this operates when clash Auto View has been selected and the total number of clash groups selected exceeds the set value. (Note: Warnings of both Clash Details... and 3D View... may be displayed. This gives the user the opportunity to perform or cancel one or both operations.)

Claim/Flush/Issue/Edit/Select All - this operates when any one of these actions is initiated for a number of clash groups that exceeds the set value. The setting also determines how many records can be present in the active pane of the 'Clash Report' window before the Select All option of the Edit menu is greyed out.

Worst Case Update Threshold

The value set for this option determines which of two methods is to be used by the software to update the clash status of elements. The methods are referred to as 'Single Update' and 'Global Update'. The Single Update method processes a single clash element, searching the database for the worst case and updating the clash element status accordingly. This method is efficient for single clashes, but the time taken is proportional to the number of clashes involved. The Global Update method is routinely used at the end of every clash run to determine the worst case clash status of all elements in the database. It uses more sophisticated processing methods and is consequently faster per element than the Single Update method, but always processes all elements.

The Single Update method is used for all elements when the number of elements is below the Worst Case Update Threshold setting; the Global Update method is used when the number is above the setting.

The optimum value for Worst Case Update Threshold depends on the speed of the system and the volume of data. This is discussed further in Clash Manager Performance Hints.
