Update an interference check after pipe network parts have been changed.
An interference check is marked as out of date 
when any pipe network part in the interference check is changed. Even changing a description on a pipe network part that is not in interference causes an interference check to become out of date. So does moving, deleting, or adding parts to any network included in the interference check.
Out-of-date icons are displayed only if the Toolspace drawing item modifier icon display is active. For more information, see Drawing Item Modifier Icons.
When you update an interference check, you can leave the interference checking conditions as they are currently set, or you can change them before rerunning the check.
Use the Interference Check Properties dialog to change interference check options, criteria, and other properties.
To change interference check conditions or properties
- In Toolspace, on the Prospector tab, expand the Pipe Networks
Interference Checks collection. - Right-click the interference check and click Interference Check Properties.
- Change information about the Interference Check Properties dialog box and click Apply to save the changes.
- Click OK to accept all changes and rerun the interference check.
- Click OK.
The interference check data is updated in the drawing and in the Prospector tree.
