The MEP Opening Marker add-in automates the coordination process for builder's work openings by converting MEP intersections into parametric void elements.

Step 1: Configure Your Global Project Settings

1. Launch Autodesk® Revit® and open your project model.

2. Navigate to the custom ribbon tab and click the Settings button under the Commands panel.

3. In the setup window, define your global requirements:

   • Offset (mm): Set the clearance buffer around your MEP elements.

   • Void Type: Choose your default opening profile (e.g., Rectangular Void).

   • Metadata: Input your project tracking data (Discipline, Location, Revision, Status).

   • Step (mm): Set your dimension round-off increment (e.g., rounding to the nearest 10 mm).

   • IFC Parameters: Define your custom IFC shared parameters to ensure accurate data mapping during export.

4. Click Save to lock in your defaults.

Step 2: Detect and Mark Intersections

1. In your active Revit view, select the MEP elements (pipes, ducts, cable trays, etc.) that you want to check against structural hosts.

2. Click the Find & Mark Intersections button on the ribbon.

3. The tool automatically evaluates where the selected services clash with structural walls and floors, instantly generating your configured opening voids at those exact cross-sections.

Step 3: Clean Up Overlapping Geometry

1. If multiple closely spaced or parallel MEP runs have created chaotic, overlapping openings, select the two adjacent void elements.

2. Click the Combine Voids button on the ribbon.

3. The system dynamically generates a new, consolidated void that perfectly encompasses both original boundaries, automatically stripping out the old instances to clean up your model and eliminate duplicate warning flags.

To Install:

1. Download the installer file from your distribution source (or the Autodesk App Store).

2. Ensure all instances of Autodesk® Revit® are completely closed.

3. Double-click the downloaded .msi or .exe installer file to begin setup.

4. Follow the on-screen prompts.

5. Once complete, relaunch Revit. The new tools will appear under your designated panel on the ribbon menu.

To Uninstall:

1. Exit Autodesk® Revit® if it is actively running.

2. Open the Windows Control Panel and select Programs and Features.

3. Scroll through your list of installed software, select MEP Opening Marker, and click Uninstall.

4. (Optional Manual Cleanup): If custom text logs or backup configuration files were saved locally during use, you can manually delete any leftover user directories located within your Windows Documents or AppData folders if necessary.
