This one is easy. Setting up a brand new model that hasn’t been worked on! The idea here is to start a new model using a template, bring in the architectural model and acquire the coordinates from that model. Easy as that!
Follow these steps to start a new mechanical model and put it on shared coordinates.
- Open Revit.
- Under Models click the New… button.
- For Template file, select Mechanical Template. See the Figure below.

- Click OK.
- Go to the Insert tab.

- Click Link Revit.
- Browse to the architectural model and link it at Positioning: Origin to Origin.
- Go to a 3D view.
- Go to the Manage tab.
- Click Coordinates, Acquire Coordinates as shown below.

- Select the link.
It’s really that easy! You now have a mechanical model on shared coordinates.
