4.2.5. Classification

Catalog parts that are going to be used in architectural CAD systems require specific classifications. Via classifications meta-information as well as “relationship-knowledge” will be hosted and transferred to the target systems. Following BIM / AEC classifications do exist today:

Classification Author Purpose
ARCHICAD CADENAS Placement / geometrical functionalities in ARCHICAD
IFC4 buildingSMART e.V. Interoperability in the BIM Branch at project- / building level
REVIT CADENAS Placement / geometrical functionalities in REVIT
OmniClass 2006 CSI Focus: Definition „what“ an object in REVIT represents (detail definition)
OmniClass CSI OmniClass 2012 is an enhancement of 2006
PDT CIBSE Attribution on international level, independent from target system (Excel)
UNICLASS RIBA / NBS Classification, „what“ product exact it is -> especially UK relevant
COBie buildingSMART e.V. Construction Operations Building information exchange - Purpose: Bridge between CAD / BIM and facility management

[Note] Note

As a high level „BIM catalogs“ should of course support as many classifications (=target systems) as possible the question often is, if they could be mapped / cross-referenced to each other. Unfortunately, with exception of the both OmniClass systems, it is no yet possible today.

Practical Example

In the following, an example part will be equipped with the Revit-Family-Templates Classification:

[Note] Note

Please proceed the same way for all other BIM classifications. The required lines for classification and attributes lines are available in PARTproject after installing the corresponding class systems.

  1. Make sure, that the REVIT class system is installed.

    If not, first use PARTupdate to get it or write an e-mail to catalogs@cadenas.de.

  2. Start PARTproject and navigate to the part where the classification should be applied

  3. Click on the dots at the end of the line Classification (REVIT).

  4. Confirm the window with OK and switch to the 3DB file in PARTproject

  5. Confirm with OK and click on the dots at the end of the line "Attributes (REVIT)".

  6. Depending on the selected class there are different attributes to be filled out now (e.g. for a door the negative solid for the cut-out in the wall must be specified). Please fill out all this fields or map them to the corresponding table variable.

  7. Confirm the window with OK and switch to the corresponding 3DB file in the PARTproject folder/file structure

  8. Open the 3DB and place the required Revit Family Template mapping Insertion point. The name can freely be chosen, but take care on position and direction.

    An instructing overview on positioning depending on product category can be found under ... <cuboids + examples in progress> .

    For assemblies, please always chose the 3DB, that contains the placement point.

    The placement point should be in a fixed / static position related to possible variants.

    [Tip] Tip

    Best practice is, if an empty geometry file is created, that only bears the placement point and which is active for all configurable variants.

  9. Right-click in the PARTproject 3D preview window and select the command Choose connection point. Then please select the entry Revit family template mapping:

  10. Please click again on the PRJ file in the PARTproject folder structure and then check if all entries are set up correctly now in the two classification lines.

  11. The classification is now complete. It is recommended, that an REVIT export check is performed additionally in order to check the correct placement and handling of the negative solid.
