When the Clashes window is displayed for the first time, the current element is displayed in the Check field. You can change this by typing any Design name or syntax.
|
Note:
|
The element name is always displayed in the Check field.

When you click Check CE, the current element name is displayed in the Check field and is then checked for clashes.
Right-click in the grid view to display a pop-up menu with the options to Print Preview and Save to Excel.
Click Print Preview to display the Print Preview window which allows you to change the page layout and print the grid view.
Click Save to Excel to display the Save to Excel window which allows you to select a destination and filename for the Excel file.
If you require a text report of the clashes, select Report to file when checking for clashes check box on the Report tab. A report is then written to a file each time a check is performed.
When checking for clashes the default obstruction is All which means the element is checked for clashes with everything in the database. To check for clashes against specific obstructions and exclusions, you can set the rules using the Obstructions/Exclusions tab. You add the elements to the Obstructions list and can exclude elements by adding them to the Exclusions list.
To add an element to either the Obstructions list or the Exclusion list, select the method of selection from the drop-down list, select the element, if required to do so and click Add.
|
Note:
|
By default the Obstructions list contains All the design elements in the current MDB.
|
To remove an element from either the Obstructions list or the Exclusion list, highlight the element and click on it and then click Remove.
To remove all the elements in either the Obstructions list or the Exclusion list click Clear. A Confirm window is displayed, you need to confirm if it want to clear the list. Click Yes to clear the list or No to cancel the operation.
Click Save to save any changes made during a session to a file. Click Restore during a session to change the settings back to your saved settings.
In the case of a laser survey the design data would be clash tested against existing conditions. You will have to clear the obstruction list and set it to Laser models in display from the drop-down list and click Add.
Creating an Obstruction/Exclusion list is not the only way you can set the obstructions. Using the Limits tab you can create an area around items or a region to create an obstruction box. Any element that lies partly or wholly within the limits box is checked. A clash between items that lie partially within the limits box is always reported, even if the point at which the clash occurs lies outside the box.
Right-click within the From or To panes but outside of the text fields to display a pop-up menu which allows you to change how the From and To limits are displayed.
You can set the limits of the obstruction box, enter the values in the text fields or select an option from the Volume drop-down list.
To disable (lock) the limits of the obstruction box, select the required East, North, Up check box.
Click Clear to set the values defining the corners of the obstruction box to zero.

The Cell method highlights the boxes in the map where clashing takes place, allowing you to quickly identify areas of concern within a model. The Cell method is quick because it requests less information from the Laser Modelling System (LMS) where the scanned referenced data is sourced.

|
The Exact method provides more detailed results, showing exactly where the AVEVA E3D™ geometry clashes with the laser model. The Exact method requires detailed point cloud data from the third party LMS, it can be slower to identify clashes, particularly in larger methods.
|
Grouping clashes per branch and then clashes against the same obstruction is a common requirement. Selecting the Group Clash/Obstruction check box presents the results using the Clash and Obstruction columns as default.
Other presentation aids are also available to you, Clash Item Aid, Clash Obstruction Aid, Clash Position Aid, Obstruction Visibility and Capping.
