Personal Clash Set

  • Last UpdatedMay 26, 2023
  • 3 minute read

During the Clash Check CE process, the AVEVA Clash Manager - Clash Set window is used to enter details of a personal clash set. This clash set is used for EVERY clash check of the CE in the particular MDB and, consequently, the default values should be used wherever possible. The Title and MDB fields are read-only. The Check List is automatically completed with details of the group element of the CE. Entries can be made in the Obstruction and Exclude lists, but it is recommended that neither is populated. In these circumstances the Obstruction list defaults to ALL and the Exclude list remains empty.

Note:
The obstruction, exclude and check lists can be modified for a clash set only if that clash set’s MDB is the same as the current MDB.

The AVEVA Clash Manager - Clash Set window includes the following items:

Set

Generated automatically as a unique index for the clash set, this cannot be changed.

Title

The title associated with the clash set, can be changed from Default or entered if the field is bank.

MDB

The name of the MDB to be used within the AVEVA Clash Manager.

Comment

Any comment to be associated with the clash set.

Obstruction List

A list of named elements or wildcards covering a range of elements and their attributes from within the specified MDB that window the Obstruction List. The popup menu option Evaluate (refer to Popup Menu for further information) may be used to verify the resultant Obstruction list is as required.

Note:
This evaluation the Exclude List is not used in deriving the resulting Obstruction list.

Exclude List

A list of named elements or wildcards covering a range of elements and their attributes from within the specified MDB. This Exclude List specifies members that are to be excluded from the Obstruction list. The popup menu option Evaluate (refer to Popup Menu for further information) may be used to verify that the resultant Exclude list is as required.

Check List

A list of named elements or wildcards covering a range of elements and their attributes from within the specified MDB that window the check list for the clash detection. The popup menu option Evaluate (refer to Popup Menu for further information) may be used to verify that the resultant Check list is as required. The TYPE of Checklist elements must be consistent, all ZONEs or all PIPEs and so on.

Note:
Where minimal clashing activity is expected SITES (or wildcards returning Sites) should be entered into the Checklist. Where much activity is expected, individual ZONEs (or wildcards returning Zones) should be entered into the Checklist. This makes sure of the best mix of parallel Clashing and Loading.

Add, +CE and Delete

Respectively have the same functions as the Add, +CE and Delete functionality of the popup menu (refer to Popup Menu for further information).

Extents

The functionality on the Extents tab is used to specify the overlap, gap and clearances.

MAP Override

If checked, causes desclash to ignore errors in the Spatial Map, which would otherwise abort the desclash run.

Check ADD

Branch Check

  • A Check checks for clashes within an item, this option is not normally recommended

  • B Check checks for clashes between different items, this option is normally used.

Modified Checklist Items Option

Some Clash Manager Admin options, including merge (compress) and reconfigure, flag every element as having possibly changed geometry. To obtain maximum benefit from Clash Check Modified Elements Only a full Clash Check will need to be executed after use of these options.
