A Countable Classification Mapping is a specific type of classification mapping that relies on sequentail data. For example, the levels in a building. A countable classification mapping has the ability to 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 as a countable classification mapping.

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

For example, if “3rd floor” is selected as a keyword. “3rd” will be read as countable numeral. the generated Keyword is “$ Floor”. $ always represents an countable value in the formula. In order for the countable value to be used, a counterpart countable formula must be selected as the model parameter. For Example, if “$ - Floor” is selected, the mapping will count through any level values that match that formula: “1st-Floor”, “2nd-Floor”, “3rd-Floor” The value of parameters and levels do not need to match the task data exactly. While the task data needs ot contain a number the level and parameter values may contain a phonetic number. The following numerals are countable levels and parameters.
In some cases a countable 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 offset of 1 objects on level 4 will be filtered to Level 3. |
