In this exercise, you run an interference check on a building model to identify and fix interference conditions.

You have created the MEP design for a multistory conference center and you want to identify and fix

interference conditions. For this, you run the interference check, export the report, and fix some interference conditions. You then run an interference check and select different elements.

You do the following:

■ Fix interferences between air terminals and lighting fixtures.

■ Fix interferences between ducts and pipes.

Completing the Exercise

To complete the exercise, follow the steps in this book or in the onscreen exercise. In the onscreen list of chapters and exercises, click Chapter 12: Working with Architects and Engineers. Click Exercise: Check and Fix Interference Conditions.

Fix Interferences Between Air Terminals and Lighting Fixtures

1. Open i_rmep_interference_checking.rvt or m_rmep_interference_checking.rvt. The file opens in the Level 2 ceiling plan view.

Note: The illustrations for the metric dataset will be slightly different from those shown here.

2. Click Collaborate tab > Coordinate panel

> Interference Check drop-down > Run Interference Check.

3. To select the element categories on which the

interference check needs to be performed, in the Interference Check dialog box:

■ Select the Air Terminals check box from the list of categories on the left.

■ Select the Lighting Fixtures check box from the list of categories on the right.

■ Click OK to run the interference check.

4. In the Interference Report dialog box:

■ Ensure that Category 1, Category 2 is selected in the Group By list.

■ Click Export.

5. In the Export an Interference Report to a File dialog box:

■ Select Desktop from the Save In list.

■ Click Save.

6. In the Interference Report dialog box, click Close.

7. On the Desktop, double-click the i_interference_checking.html

(m_interference_checking.html) file to view the interference report in a browser window.

Note: Windows Vista users may need to rename the file saved on the desktop, from i_rmep_interference_checkinghtml (m_rmep_interference_checkinghtml) to i_rmep_interference_checking.html (m_rmep_interference_checking.html).

8. Close the browser window after viewing the interference conditions.

9. In the Revit MEP application window, click Collaborate tab > Coordinate panel >

Interference Check drop-down > Show Last Report.

10. In the Interference Report dialog box, under Message:

■ Expand Lighting Fixtures, if necessary.

■ Under the first Lighting Fixtures parent row, select the air terminals row with ID 728098 (536984).The two interfering elements are highlighted in the Level 2 ceiling plan view.

Tip: Zoom in to the upper-right corner of the drawing for a better view.

11. To highlight the overlapping elements in the ceiling plan view, in the Interference Report dialog box, under Message, first Lighting Fixtures parent row, select the lighting fixture row with ID 803364 (585440).

12. To highlight the interference of the air terminal with the lighting fixture with ID 803367

(585279), in the Interference Report dialog box, under Message, second Lighting Fixtures parent row, select the air terminal row with ID 728040 (536867).

13. To start removing the interference from an overlapping air terminal and a lighting fixture, in the Interference Report dialog box, under Message, first Lighting Fixtures parent row, select the air terminal row with ID 728098 (536984). This highlights the interference of the air terminal with the lighting fixture with ID 8083364 (585440).

14. Click anywhere in the view window.

15. In the view window:

■ Zoom in to the upper-right corner of the drawing, if required.

■ Move the cursor over the lighting fixture that overlaps with the air terminal, as shown.

■ Click to select the lighting fixture.

16. Activate the Move tool.

17. In the view window, click the upper-right corner of the lighting fixture.

18. Click the right corner of the ceiling grid above the lighting fixture, as shown, to move it up.

19. Exit the Move tool.

20. In the Interference Report dialog box, click Refresh.

Notice that the interference between the air terminal with ID 728098 (536984) and the lighting fixture with ID 803364 (585440) is no longer reported.

Note: When you click Refresh, the interference tool does not rescan the building model for new interferences. It scans only the previously found interference pairs to check whether the interference was corrected.

21. In the Interference Report dialog box, under Message, select the air terminal row with ID 728040 (536867) to highlight the element in the ceiling plan view.

22. Remove the interference from the selected air terminal and the corresponding overlapping lighting fixture.

23. In the Interference Report dialog box, click Refresh.

Notice that the interference between the air terminal with the ID 728040 (536867) and the lighting fixture with the ID 803367 (585279) is no longer reported and the Message list is empty.

24. In the Interference Report dialog box, click Close.

97 Fix Interferences Between Ducts and Pipes

1. Open the Room 214 3D Fire Protection (Room 53 3D Fire Protection) view.

2. Draw a selection box around all the elements to highlight the ducts, duct fittings, air terminals, flex ducts, mechanical equipment, pipes, pipe fittings, and sprinklers.

3. Open the Interference Check dialog box to run another interference check.

4. In the Interference Check dialog box:

■ Under Categories From on the left and right, ensure that Current Selection is selected from both the lists.

■ Clear all check boxes except Duct Fittings, Ducts, and Flex Ducts from the categories list on the left.

■ Clear all check boxes except Pipes from the categories list on the right.

■ Click OK.

5. In the Interference Report dialog box:

■ Ensure that Category 2, Category 1 is selected in the Group By list.

■ Expand the tree, if required.

■ Notice that only interferences involving the selected ducts and pipes are reported. You can fix the interferences, as required.

For Metric users, notice that interferences involving the selected ducts, duct fittings, and pipes are reported.

■ Close the dialog box.

6. Close all files without saving changes.

Chapter Summary

You have learned to coordinate and monitor changes in files linked to Revit MEP and create a robust project design. In addition, you can perform interference checks to detect and resolve conditions during the design phase to limit cost overruns and the number of design changes during construction.

In this chapter, you learned to:

■ Monitor changes in files of other disciplines linked to Revit MEP.

■ Check and fix interference conditions.
