Import
- Preferred Profile
- Select the profile proposed by default to filter and import IFC files.
- For Coordination: Suitable for a lightweight model imported
for markups and stakeholder review, imports the file as a root object (AECSite or
AECBuilding) and a CGR representing the content of the file.
Should be used with IFC Geometry as set to Tessellated.
- For Construction: Suitable for a full PLM 3DEXPERIENCE model imported to be used across all brands for issue tracking, reference in
tasks or project management, BOM generation, construction simulation and
operations/maintenance tracking. Typically a complete model received by a
construction company that needs to be purchased, fabricated, and constructed.
Set IFC Geometry as value as desired.
- For Design: Suitable for a lightweight model, to keep the exact geometry and the IFC attributes. All the products are grouped under an AEC Feature. The geometry is a volume. The feature is a volume feature.
- For Coordination: Suitable for a lightweight model imported
for markups and stakeholder review, imports the file as a root object (AECSite or
AECBuilding) and a CGR representing the content of the file.

By default, Preferred Profile is set to
For Coordination. - IFC Geometry as
- Select the required option:
- Exact: IFC geometry is imported as boundary representation
(B-Rep). If the creation of the B-Rep fails, Converter for IFC tries to import the geometry as tessellated.
The imported objects can be measured, used in collision detection, and in some cases, in solids with editable faces.
Note: IfcTriangulatedFaceSet is always directly imported as tessellated. - Tessellated: IFC geometry is imported as tessellated. If
the import as tessellated fails, Converter for IFC tries to import the geometry as B-Rep. The B-Rep is then tessellated and stored
in CGR format.
This option is faster and requires less storage space. The resulting CGR objects are mainly used for visualization.
- Optimized Exact: IfcFacetedBrep are imported as
tessellated, other geometries are imported as if Exact was
selected.
To be used when the IFC file contains IfcFacetedBrep composed of thousands of small planar faces. Exact would consume too much time and storage space.
Notes:- IfcFacetedBrep cannot be imported directly as tessellated when used as operand of an IfcBooleanResult solid. They are imported as B-Rep solids.
- All the geometries imported from an IfcShapeRepresentation must be contained in a single 3D Shape representation (Part or CGR representation). As a consequence, when an IfcShapeRepresentation contains multiple ge.ometric representations that cannot all be imported as tessellated geometry, all IfcFacetedBrep entities belonging to the IfcShapeRepresentation are imported as B-Rep solids.
By default, IFC Geometry as is set to
Tessellated. - Exact: IFC geometry is imported as boundary representation
(B-Rep). If the creation of the B-Rep fails, Converter for IFC tries to import the geometry as tessellated.
Export
- IFC Release
- Defines the IFC release used for the export.
By default, the IFC release is 2x3.
- Tessellated Geometry
- Available when the IFC release is IFC 4 and IFC 4x1.
- Exports tessellated geometry, when given the choice between exact and tessellated geometry: When selected, IfcFacetedBrep solids are created. Otherwise, IfcAdvancedBrep solids are created.Note: A tessellated solid is always exported as IfcFacetedBrep. By default, this check box is selected.
- Export Also NoShow entities
- Export entities found both in the Show and the NoShow spaces are exported. Be aware of the following:
- For a better control of the 3D shapes representation to export when a product has multiple representations, a 3D shape representation that is in NoShow is exported only if its parent product is also in NoShow.
- When a product with multiple 3D shape representations is in Show, this product is exported with the first 3D shape representation that is attached to it. The other 3D shape representations are not exported.
By default, this check box is not selected.
