True North from the linked project. The origin of the linked project's shared coordinates becomes the origin
of the host project's shared coordinates.
When a Revit Architecture project acquires coordinates from a linked DWG file, the World Coordinate
System (WCS) of the selected linked DWG file becomes the shared coordinate system of the host Revit
Architecture project, based on the location of the linked DWG instance. The Y axis of the DWG becomes
True North, and the origin of the DWG becomes the origin of the shared coordinate system of the Revit
Architecture project.
To acquire coordinates:
1 Click Manage tab
➤
Project Location panel
➤
Coordinates drop-down
➤
Acquire Coordinates.
2 Place the cursor on a linked model instance, and click.
The host model file now has the same shared coordinates as the linked model file. If other loaded linked
models share coordinates with the host model, they also acquire the new coordinates.
Publish Coordinates
When you publish shared coordinates from a host project to a linked project, this changes the linked project.
The host project's True North and shared origin are recorded in the linked project, based on the current
location of the linked instance. This location is now named in both the host project and the linked project.
More than one location of the link can be recorded.
When you publish shared coordinates from a host Revit Architecture project to a linked DWG, this changes
the linked DWG. The origin of the host Revit Architecture project’s shared coordinate system becomes the
origin of a new User Coordinate System (UCS) in the DWG file. The Y axis of the new UCS corresponds to
the host project's True North. You can name the UCS when you publish coordinates. It is not recommended
that you change this name after publishing coordinates.
To publish coordinates:
1 Click Manage tab
➤
Project Location panel
➤
Coordinates drop-down
➤
Publish Coordinates.
2 Place the cursor on a linked model instance and click.
3 Select a named location from the linked model, and click OK.
See Defining Named Locations on page 1296.
The linked model file now has the same shared coordinates as the host model file.
Acquiring or Publishing Through Linked Instance Properties
This procedure assumes that you have a linked model instance in the host model, and its coordinates are
not currently shared with those of the host model.
1 Select the linked model in the host model and click Modify RVT Links tab
➤
Element
panel
➤
Element Properties.
Notice the button in the value box next to the Shared Location parameter. It reads Not Shared,
which indicates that there is no coordinate sharing between the linked instance and the host
model.
2 Click the button.
Because this is the first time that you are setting up shared coordinates between the host and
the linked models, a dialog displays, telling you that you need to reconcile the coordinates in
favor of the host or the linked model. You need to reconcile the coordinates only once.
