IFC

To open IFC files (2x Edition 3) in HiCAD, select

Open >

Step, Iges..., then select the desired *.ifc file from the dialogue.

To export a HiCAD drawing in IFC format, select

Save as... >

3-D formats (Step...), and save the file in the *.ifc format.

On the right hand side of the export dialogue window you can specify the following settings:

Parts to be exported: Here you can select whether you want to save the complete drawing (All), or only selected parts (Selection list).

Prefer CONTOUR part: If you activate this checkbox, HiCAD will check during export whether a CONTOUR representation exists. If this is the case, it will be exported. If no CONTOUR representation exists, the EXACT/SIMPLE representation will be exported, which will also happen if the checkbox is not activated.

Unite sheets: Activate this checkbox if you want all sub-parts (also flanges and bend zones) of a sheet metal part and its superordinate part to be combined into one part for the export.

Unit of length: Via this option you can select whether the length specifications in the IFC files are to be output in Millimetres (mm), Metres (m) or Inches (inch).

Export standard parts: By activating or deactivating the checkbox you can specify whether Standard parts (bolts, screws, roller bearings, springs etc.) are to be included in the IFC export or not.

In the Configuration Editor at Active Configuration (Base configuration) > Interfaces > IFC you can specify which export options are to be activated or deactivated by default upon function call. Also, you have the option to define an Attribute mapping configuration for Import and Exportthere.

Please note:

3-D CAD formats (Step, Iges, ...) imported to HiCAD will automatically be opened in a new drawing file.

If any standard beams/profiles are contained in an IFC file, they will only become the corresponding standard parts in HiCAD if the designation of the profiles in the IFC file corresponds to those in HiCAD. Use the mapping table in the Catalogue Editor (Catalogues > Factory standards IFC interface > IFC mapping ISD) to specify how standard parts are to be transferred from IFC to HiCAD.

HiCAD supports the Coordination View 2.0 Subschema. Further information, as well as an overview of the entities it comprises, can be found on the website of buildingSMART International:

IFC supports all geometry-, properties-, project- and product-relevant objects listed in the Excel file on sheet CV-V2.0-IN:

Special IFC-product-based objects (e.g. electric components) are not interpreted separately, i.e. only connected geometries will be processed (including properties such as Materials/Colours/PropertySets etc. and parameterisations, e.g. for beams and profiles.
