CAESAR II Version
12
CADWorx Version
20.0 (2020)
CADWorx Structure Version
2020(4.0)

Allows you to map components to IFC element classes supported by available BIM software. This feature allows you to see the geometry and properties of your CADWorx components in BIM software, such as Revit.

IFC Version

Specifies the version of the IFC file.

  • IFC4

Specifies to save the file as an IFC4 version. You can import and view .ifc files in NavisWorks, BIM software such as Revit, and ArchiCAD, among many others.

  • IFC2X3

Specifies to save the file as an IFC2X3 version. You can import and view .ifc files in NavisWorks, BIM software such as Revit, and ArchiCAD, among many others.

Representation Type

Specifies one of the following component representation types:

  • BREP - Boundary Representation

Uses BREP for the .ifc export, which represents shapes using limits.

  • CSG + BREP - Constructive Solid Representation

Uses CSG + BREP for the .ifc export, which creates an object by applying Boolean operations on the simpler objects in the model. The software typically converts 75 percent to 80 percent of components into solid representation. The software may not convert a component into a solid representation if the component is:

  • Too complex.

  • Not supported by the BIM software. You cannot see unsupported converted graphics.

The remaining components export as BREP (Boundary Representation).

  • The software represents CSG components with solid geometry, which allows for snapping and other useful operations.

  • CSG has a reduced file size when compared to BREP, which increases performance while loading the file into a BIM software.

  • Most BIM software supports BREP.

IFC Mapping

Specifies the mapping configuration for the .ifc file.

  • Standard

Loads the standard out-of-the-box mapping configuration file (.mp) according to IFC standards. You cannot save changes to the out-of-the-box standard .ifc mapping configuration file.

  • Click Save As to save changes to the file. You can then use the modified file as your Standard, or load it when you select User-defined.

  • Revit

Loads a built-in mapping configuration for Revit software with the available geometry and properties. You cannot save changes to the out-of-the-box Revit .ifc mapping configuration file.

  • Click Save As to save changes to a new file name.

  • User-defined

Allows you to select an .mp file for defining a mapping configuration supported by your BIM software. You can save any changes made to the user-defined mapping configuration file using the Save option.

  • Click Save As to save changes of the file to a new file name.

Path

Specifies the location of the .mp file.

Load

Allows you to load a user-defined .mp file.

CADWorx Component

Lists the CADWorx component type including piping, equipment, and structure.

IFC Element Class

Lists the suitable IFC element classes for a component type.

  • To change the IFC Element Class, click the element class listed, and then select an item from the list provided.

  • If you do not see a suitable element class supported by your software in the available list, then you can add additional supported IFC element classes for any component. To make changes to an .xml file, open the file in a text editor, and then add any IFC element class to the listing. The .xml files are delivered to: C:\Program Files\Intergraph CAS\CADWorx Design Review 2017\IFC_Configurations.

Save

Allows you to save changes to a user-defined mapping configuration.

Save As

Allows you to save changes to a mapping configuration file to a new file name.
