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

A Repeating Classification Mapping is a specific type of classification mapping that relies on sequentail data. For example, the levels in a building. An repeating classification mapping has the ability to iterate over multiple different values and create a separate filter for each match between the schedule and BIM data.

Creating the most powerful mapping requires a strong understanding of the BIM and 4D data in the project. The following classification mapping types can be used iteratively:

• A Level classification mapping can iterate through each level.

• A Zone classification mapping can iterate through each zone.

• A Parameter classification mapping can iterate through each value of a given parameter.

To create a repating classification mapping a keyword needs to be selected that contains a formula with a repeatable numeral. Possible numerals that are repeatable are:

• Integer : 1, 2, 3, 4… OR 01, 02, 03 ,04…

• Phonetic : One, Two, Three, Four…

• Ordinal : 1st, 2nd, 3rd, 4th

• Alphabetical : A, B, C, D

For example, if “3rd floor” is selected as a to create a keyword. “3rd” will be read as an repeatable numeral. the generated Keyword is “$ Floor”. $ always represents an repeatable value in the formula. In order for the repeatable value to be used, a counterpart repeatable formula must be selected as the model parameter. For Example, if “$ - Floor” is selected, the mapping will repeat through any level values that match that formula: “1st-Floor”, “2nd-Floor”, “3rd-Floor”

In some cases a repeating classification mapping may need to be slightly offset. For example, the ceilings on level 2 may fit better if constructed by tasks with the level 3 Parent. Or instead of a level the user is using a revit parameter like “top constraint” which is ussually a level higher than the level the object is on.

An offset can be used to ensure that objects are assigned to a different level. when using an offest of 1 objects on level 4 will be filtered to Level 3.
