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 read 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:as a repeating classification mapping.

• A Level classification mapping can iterate repeat through each level.

• A Zone classification mapping can iterate repeat through each zone.

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

To create a repating repeating 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 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 offset of 1 objects on level 4 will be filtered to Level 3.

A Location Classification Mapping can be used in conjunction with a level classification mapping when level data includes information about the location of the object as well as the level it is on. For example, if a building has multiple wings and the information regarding which wing the object exists in is located in the level BIM data a compound repeating mapping is most effective.

A level classification mapping must be created first with a specific type of value in order to add a location classification mapping. A level and location classification mapping will work together to properly assign objects to the schedule.

The level classification mapping should be created using a keyword that only contains the level number.

A level with two numerals needs to be selected for the pameter value of the level mapping. Each numeral will be displayed as a separate $. This mapping will not work by defaultWhen using a level with this data a location classification mapping is needed.

When a level with two numerals is selected the level list is regenerated creating two additional options that allow the user to distinguish between the level and the location for the given level value. By default the option where first numeral in the formula denotes the level is selected.

If the second number in the formula contains the level data. Select the drop down menu again to pick between the available options. The two choices are displayed using either a '[NUMBER]' or a '$' to denote each numeral. The value formula for a level classification mapping should display the level as a $ and the location as [NUMBER].

To complete the classification mapping a location classification mapping must be added and an associated keyword must be selected. For example BLDG 2 can be selected.

The location classification mapping is only available when a level classification mapping is created as described above and it its automatically assinged to the associated Level with the opposite formula. The value formula for a location classification mapping should display the Location as a $ and the Level as [NUMBER].

The above mapping is extremely powerful. Assuming that other tasks in the schedule follow the same structure objects on all levels and in different buildings can be assigned with a single Mapping.
