For each mapping there are two separate lists of classification mappings. The lists display and allow the user to control how parameter classification mappings function.

The Repeateable Location Level and Associated Parameters list contains all level, zone, document and explicit or repeating parameter classification mappings. All objects must match the rule defined by the classification mappings that appear in this list.

The Combination of Parameters list contains a list of parameter classification mappings for which all object must match at least one of the classifications defined.

The first parameter that is added to a given mapping is always added into the Combination of Parameters list. For any single parameter classification mapping all objects still need to contain the specified BIM data. If the parameter is set as repeatable it is automatically moved to the Repeatable Location Level and Associate Parameters List.

When additional parameter classification mappings are added the user is allowed to select Parameter-AND or Parameter-OR.

The Parameter - OR option places the newly created parameter classification mapping into the Combination of Parameters list.

The Parameter - AND option places the newly create parameter classification maping into the Repeateable Location Level and Associated Parameters list

The Combination of Parameters list allows the user to specify multiple inclusive classifications to filter objects. If a given object meets the criterium of the mapping if it contains the BIM data values that are specified in any of the classifications.

The image below shows two parameter classification mappings using the category parameter. In this example both walls and structural columns are assigned to tasks with the keyword ‘Cols and Walls'.

In some cases an additional non repeating parameter classification mapping needs to be added where objects need to meet its criterium. For example, we could expand on the previous mapping to include a workset that all the columns and walls need to be part of. This parameter classification mapping needs to be added to the Repeateable Location Level and Associated Parameters list.

The Parameter - AND option is used to create a parameter classification mapping that specifies BIM data that all objects need to contain.

In the above example all structural columns and walls in the structure workset are assigned to tasks with the ‘Cols and Walls’ keyword

Generally speaking mappings do not apply the same objects to more than one task. In some situations the user may want to add the same objects to multiple tasks using 4D automation. An additional task can be added to the mapping if it has the same parent as the task that was used to create it.

The task name of the added task is appended to the existing 4D Data.

The image shows the task Set Brace, and Install Rebar included in the same mapping.

Adds an additional task to the currently selected Mapping.

Additional classification mappings need to be created in order to specify which keyword in the new task name should be used to filter the objects to the task. In the Example Below Walls are assigned to tasks with both the “Set Brace” and the “Install Rebar” keywords.

When using compound keywords it is important to understand that any classification mappings contained in the repeatable Location, Level and Associated Parameters list must meet all tasks that objects are assigned to. A safe way to ensure that all tasks meet the criteria is by using keyword that exist in thier shared parents.
