Hello,

Run an interference check to identify parts in a pipe network that collide or violate proximity criteria.

You can check for interferences on a single pipe network, or you can check two pipe networks to determine if parts collide or violate proximity criteria.

Easy enough to do, after you have your pipe networks already created in your drawing you will notice under your Prospector -->Pipe Networks that you now have the option for Interference Checks. Simply right click on Interference Checks and select New, Then you must select a part from the first pipe network you want to check -->Next, you want to select another part from the same network or a different network to bring up your Create Interference Check dialog box.

Give your check a name, make sure you have the correct networks selected for 1 & 2,

When you run an interference check, you can enable or disable 3D proximity checking criteria.

If you enable the 3D proximity checking option on an interference check, you can identify pipe network parts are too close to one another in their 3D representation, according to a specified distance or scale factor. You can check a single pipe network or two pipe networks.

When you use proximity checking on a single pipe network, interferences are created for parts that are less than a specified distance from one another. When you use this feature to check two pipe networks, an interference is created for any parts from one network that are less than a specified distance or scale factor from any parts in the second network.


You can use the 3D proximity check feature to ensure that the distance between two different types of utility networks meets a certain requirement. For example, a sewer and water crossing typically requires that the water line be a minimum of 18 inches above the sewer line. Running an interference check with the Use Distance option set to 18 inches identifies any parts that were less than 18 inches away from the other pipe network.

After running an interference check, view the results in the drawing or by looking at the data in the Toolspace list view.

In the drawing, interferences are displayed according to the choices defined in the Interference and Render Material style options specified on the Create Interference Check dialog box. These choices are also displayed on the Information tab of the Interference Check Properties dialog box.

To view interference data in the list view, in Toolspace, on the Prospector tab, expand the Pipe Networks Interference Checks collection. Click on the Interference Check object in the Prospector tree. The interference data is displayed in the list view. You can right-click on the status column and Zoom To an interference in the drawing. If you choose Delete, it deletes only the interference, not the part. In this view, you can also right-click an interference and select Properties to display the Interference Properties dialog box.

Happy checking
