When working in a bigger model, it could be hard to find out which assembly instance is the master (The master is the instance for which the assembly views are connected to). It is important to know this information when changing one instance of an assembly, while the rest should remain the same. IMPACT now got the functionality to make this step easier.

IMPACT Master Instance Parameter

When generating a shop drawing for an assembly, IMPACT automatically populates the parameter "IMPACT Master Instance" with information on which instance is the master and which are not. 


Figure 1: The parameter "IMPACT Master Instance" is populated when a shop drawing is generated for the assembly

With this parameter, it is easy to create a filter that provides the required information. One can find an example of how to set up this filter below.

Set up the filter

Note: One can set this up in the project template so that it exists in all future projects. 

  1. Create a copy of one of the 3D views. Rename it. 
    Figure 2: Create a new 3D view
  2. Open the view and start to create the filter. Start the "Visibility/Graphics" in View/Graphics/Visibility/Graphics

    Note: If this is done in an existing project, please complete the steps below first, and then go back.

  3. Go to the "Filters" tab and click "Edit/New".
    Figure 4: 
  4. Create a new filter with the icon (2) and name it something.
    Figure 5: Create a new filter
  5. Continue with assigning the filter to one category. In this case, select "Assemblies" (5) since the parameter should show information for the assembly. Set the rule by selecting the parameter "IMPACT Master Instance" (6) and set it to "Equals" (7) "Yes" (8). This will mean that when the parameter is set to "Yes", Revit can filter out the instances with this value.
    Figure 6: Set the rule
  6. The next step is to configure what the filter should do in the model. Click on "Add" (10) and select the new filter (11).

  7. Decide how the instances with value "Yes" should be highlighted. Override the pattern (13) and set the pattern (14) and the color (15). In this example, they will be shown highlighted as solid green.

  8. Now, all instances that got the parameter "IMPACT Master Instance" set to "Yes" will be highlighted in the view.

Using the functionality in an existing project

When creating a new project, the new parameter will be added and configured automatically. However, if this should be used for an existing project, one needs to do this manually. 
Figure 11: The parameter will not exist in existing projects

  1. Start the dialog for "Project Parameters" located under Manage/Settings/Project Parameters. Add a new parameter (2) and search for the shared parameter "IMPACT Master Instance" in the parameter group "IMPACT Element Information" (5).
    Figure 12: Add the parameter
  2.  Decide which group the parameter should be grouped under (8) and assign the category (Assemblies) (9).
    Figure 13: Set group and category

The parameter will exist now. One can continue with the steps above
