1. Click File > Save. The Save file browser opens.
2. In File Type, select IGES (*.igs).
3. Click Options. The Save IGES dialog box opens.
The following options are available in the Save IGES dialog box when you select the IGES format:
• Healing for: The healing step for a specific destination system.
• Version: The version of the IGES file: either version 5.2 or 5.3.
• Tolerance: If you select Generic IGES for healing, then the maximum part resolution of all exported parts is used. You can make the resolution coarser by changing the Tolerance value here.
• Units: The units to use. Defaults to Millimeter.
• Export Empty Parts: Parts without geometry are exported.
• Export Containers: Containers below parts and assemblies are exported. The container usually becomes an assembly, so parts saved in a container will be saved into the new assembly.
• Save as Solid: Write bodies as IGES type 186 (Manifold Solid BREP). Some CAD systems can use this type to import a solid part.
• Convert to NURBS: Convert analytically described curves and surfaces to a Non Uniform Rational B-Spline (NURBS) representation.
• Degen Curve: Select the method you want to use for handling degenerated 3D curves. Degenerated curves occur for special surfaces, such as the tip of a cone or one side of a corner blend surface that contains degenerated 3D curves without being degenerated itself. These are often called singularities of the surface. Creo Elements/Direct Modeling treats these singularities in a special way to avoid corrupting the part. This applies to both analytic and splinar surfaces. You can choose how these degenerated elements are transferred to the IGES file:
◦ 2D only: No 3D representations of degenerated curves.
◦ 3D only: No 2D representation of degenerated curves.
◦ Rem 3D and 2D: No representation of either 3D nor 2D degenerated curves.
• Curve on Surf: The method you want to use to transfer trimming information. This applies to both internal and external boundary curves. Possible settings are:
◦ Not Specified
◦ Use 2D
◦ Use 3D is the preferred setting because Creo Elements/Direct Modeling models usually have accurate 3D edge geometry representations. However, 2D descriptions may be better for some target systems.
• Statistics: The name and location for the
export log file. Leave this field blank if you don't want to save a log file.
• Header Section: Adds information to the IGES file global section. Type values for the available fields.
