Please find below an Object Type mode 'Reference' for a Door with a Design Table.

This means that when instantiating in Change LOD, it won't create new reference, but instantiate existing (it creates only the first of each configuration).

(R2025x model)

The configuration table (for information):

And how to use it:

Here are the main principles:

• Create a Typed object with skeleton
• Create an excel sheet with:
  • Configuration in first column
  • IfcDoorType_Tag in second column to make the PLM mapping work
  • Ifc naming logic if you want property sets to be valuated
  • User parameters to be mapped to UDF parameters
• Create a Design Table to link user parameters to the design table (mandatory for PLM side)
• Create a formula where the DT configuration=IfcDoor_Tag->ToReal() (mandatory for PLM side)
• Create the geometry of the door 
  • Create a base axis system
  • Don’t forget to create a f(x) for the base axis system
  • link with parameters
• Create a UDF
  • Don’t include the DT in the UDF (deactivate it before if it is added automatically)
  • Define door parameters you want to be able to modify at instantiation
  • Name parameters for Quantities with the Ifc naming logic (like ifcQto_DoorBaseQuantities_Area)
  • Output for opening must be named ‘Opening’
• Create an Object Type with ‘Reference’
  • Add the DT, the Typed Object
