The additional options for the IGES documents provides some advanced options for the file conversion rules which output file type is IGES.
| IGES solid/surface entities | Exports the data as solid or surface entities. |
| Trimmed Surface (type 144) | Converts the faces of the part or assembly to trimmed surfaces in the IGES file. | |
| Manifold Solid B-rep Object (type 186) | Exports boundary representation (BREP) data to the IGES file. |
| IGES Wireframe (3D curves) | Converts the solid body to a 3D wireframe representation in the IGES file. Depending on the entity types required by the target system, select: |
| B-Splines (Entity type 126) | ||
| Parametric Splines (Entity type 112) |
|
If you select both IGES solid/surface entities and IGES Wireframe (3D curves), the model is exported as both trimmed surfaces and 3D curves. |
| Surface representation/System preference | Affects files exported as IGES solid/surface entities. Select a target system to determine the IGES entity types that compose the trimmed surfaces. |
| Export 3D Curve features | Includes 3D curve features in the exported file. |
| Export sketch entities | Includes sketch entities in the exported file. All 2D and 3D sketch entities are included. |
| Use high trim curve accuracy | Affects files exported both with Trimmed surfaces and with 3D curves. High trim curve accuracy can sometimes help if the target system has trouble importing the IGES file or cannot knit the surfaces into a useful solid. The file size is larger if the check box is selected. |
| Save all components of an assembly in one file | Saves all assembly components, sub-assemblies, and sub-assembly components in one file. Otherwise, the assembly components and the sub-assembly components are saved as individual IGES files in the same directory. |
| Flatten assembly hierarchy | Flattens the assembly to one level of only part bodies. A flattened file contains a top-level assembly and a series of parts that contain imported features. |
|
NOTE: The IGES assebmly structure options can be used only with the assemblies. |
| Reset All | Resets all additional options to their default settings. |
