Plant rooms and ceilings are full of services, and tracing them by hand takes days. Fit MEP lets you model MEP from point cloud scans in Revit: click a run in the scan and the pipe, duct, cable tray or conduit is created at the fitted size and position.

Why model MEP from point cloud data

• Size and position from the scan. Diameters and duct sizes are fitted to the points, and the run is placed on its real axis.
• Standard sizes. Sizes can snap to the sizes defined for the pipe, duct, tray or conduit type in your project.
• Straight, tidy runs. Runs that are almost vertical, horizontal or on a project axis are straightened.
• All in one panel. Pipe, Duct, Cable Tray and Conduit are tabs of one dockable panel.

Before you start

1. Link the point cloud and make sure the project has levels.
2. Load the pipe, duct, tray and conduit types and systems you need.
3. Click Fit MEP on the Zeta BIM tab and choose a tab.

Steps

1. Choose the type and the system, for example Pipe Type and Pipe System.
2. Choose the Pick mode:
   • 1 click · auto: click one point on the run; its length is found.
   • 2 clicks: pick the start and the end point.
3. Click Create and click runs in the point cloud. Press Esc to finish.

Options by tab

Placement and geometry

• Ref. Level: Auto uses the nearest level below the picked point.
• Axis regularization: align runs to Vertical, Horizontal or Project axes when they are within the angular tolerance. In plan, runs can also follow the direction of a straight grid line.

Good to know

• If the project has no duct type of the chosen shape, the panel asks you to load one and press ⟳ to reload.
• The type lists can be searched by typing.
• To connect runs afterwards, use MEP Corner / MEP Tee.
