Setting IGES Export Options

Set the export options when you export SOLIDWORKS part or assembly documents as IGES files.

1. Select from the following options:

   Option	Description
   Solid/Surface features	Output as 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) Type of IGES 3D Curve Exported B-splines (entity 126) 126, 110, 102*, 100 Parametric splines (entity 112) 112, 110, 102*, 100 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. Surface Representation Surface Representation Exported IGES Entity Types STANDARD 144, 142, 128, 126, 122, 120, 110, 102, 100 NURBS 144, 142, 128, 126, 110, 102, 100 ALIAS 144, 142, 128, 126, 122, 120, 110, 102, 100 ANSYS 144, 142, 128, 126, 110, 102, 100 COSMOS 144, 142, 128, 126, 110, 102, 100 MASTERCAM 144, 142, 128, 126, 110, 102, 100 SURFCAM 144, 142, 128, 126, 110, 102, 100 SMARTCAM 144, 142, 128, 126, 110, 102, 100 TEKSOFT 144, 142, 128, 126, 110, 102, 100 ALPHACAM 144, 142, 128, 126, 110, 102, 100 MULTICAD 144, 142, 128, 126, 110, 102, 100 If the system you are exporting to is not listed, refer to the documentation for that system to see which entities are supported, and choose an appropriate setting.
   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.
   IGES assembly structure	Save all components of an assembly in one file (assemblies only). Saves all assembly components, subassemblies, and subassembly components in one file. Otherwise, the assembly components and the subassembly components are saved as individual IGES files in the same directory. Flatten assembly hierarchy (assemblies only). 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.

2. Click OK.
   When you create a task, you click Options in the task properties dialog box to change the options for that task only. To change the default option values, click View > Options > IGES .
