Setting up for linked model

Before starting the actual registration, we need to follow the below steps to setup the model. 

It is recommended to check the below points by opening the linked model on it own:

• • Assign the room use of the Rooms by using the Name property. They cannot be updated from the current Host model.
  • Rooms and Windows can be registered to test if there is any issue with registration or Room-Window attachment. Although the registration is not carried to the Host model, Please remember to unregister them before linking to the Host model. 

Once the model is linked to the Host model:

1. Assign Mark for each linked instance which will be used as Building name when registering the rooms and windows from that instance.
   • Select the link instance > Right-click on it.
   • Click on the properties option.
   • On the Properties palette, Assign the Mark. (See the image on right.)
2. Enable Rooms and Windows detection and selection options from settings.
   • Open the MBS setting dialog.
   • Then go to Project settings > General Tab.
   • Tick the Allow Rooms & Windows from Links and Select Rooms & Windows from Links options.
3. After these setups, you can register Windows and Rooms as usual.

Known Limitations

1. The Room and Window name and result cannot be shown using Revit Tag objects. They are shown using Revit Text objects instead. 
2. The Linked model doesn’t store any registration or result information. All these information are stored in the Host model. So if the Linked model is linked to a new host model after registration, there will be No registration or result information. The information can also be lost if the linked model is Removed from the Manage Links dialog. Unload and Reload From will preserve the information.

When the linked instances are in different elevations, the result might not be visible in default levels. In that case, you might be interested in creating your custom plan view, for this, there is an option to do so in MBS Daylight for Revit Software. Please follow the following instructions.

1. Go to MBS Daylight for Revit option on the Revit Ribbon menu.
2. Under Utility Tools click on the Manage Linked Model Plan View option.
3. This will open up the new dialogue box.
4. On the dialogue box, ensure you have provided the correct data such as FloorPlan Template, Tolerance and Prefix.
5. Next, click on Select revit links.
6. Once you select the links, it will display the levels to be created that match the Tolerance. For tolerance, link instances are compared against the lowest elevation among the selected links.
7. Next, click on the Create Floor Plan button.
