Interference Checking

The Interference Check tool searches conflicts among a set of selected elements or all elements in the model.
The purpose of the tool is to detect conflicts and reduce foreseeable construction risks.

Collisions occur when one BIM object overlaps another BIM object due to lack of space between them, e.g. when walls, beams and columns collide with pipes, ducts or fittings.

Collisions between an architectural and structural model can be made visible.

Note: The command is available in MEP module only.

You can export the report of conflicting BIM elements.

To run an interference check:

Start the Interference Check command and the dialog opens.

If you have selected elements in the view, the dialog is filtered to display only those element on the left side of the dialog.

If you did not select any elements, the dialog displays all categories.

On the left side of the dialog, select an element type.
For example, select Wall.

On the right side of the dialog, select the target element type.

For example, to run a wall-pipe interference check, select wall on the left side and pipe on the right side.

If no interferences are discovered, a dialog displays the empty result.

If interferences are discovered, the Interference Report dialog displays. The dialog lists all elements that are in conflict with one another.

Interferences are grouped according to the way you generated the check.
To see one of the elements that is intersected, select it in the Report list, and click Show.
The current view displays the affected elements.

If you wish you can fix the problem and then run again the interference check.
If the problem has been resolved, the problem elements are removed from the list of conflicts.

You can generate an HTML version of the report. In the Interference Report dialog.
Enter a name, navigate to the desired folder to save the report, and click Export.
