IGES Export Dialog OptionsKeyCreator / File / Export / IGES Export / IGES Export Dialog Options
The following settings are available in the IGES Export Options dialog that appears when OPTIONS is selected from the File Save window. Header Information
Export Solids As
Export Analytic Surfaces and Procedural Surfaces as B-Spline SurfacesUse this option when the receiving application requires surfaces to be B-spline surface definitions. Export Analytic and Procedural Solid/Sheet Body Edge Curves as B-Spline CurvesWhen checked these edge curves will convert to type 126, and are actually converted to NURBS splines. Split Periodic Surfaces in TwoWhen selected (the default), periodic surfaces are split in two prior to export to IGES. (A periodic surface is a closed surface that joins itself smoothly. For example, a spherical surface is periodic in both the U and V directions. A cylinder is periodic in the U direction.) We recommend selecting this check box for better compatibility when exporting to systems such as Mastercam® and CATIA®. Also, this matches the behavior of the IGES Geometry translator in KeyCreator 4.x. Clearing this check box ensures that periodic surfaces are not split. This matches the behavior of the IGES geometry translator in KeyCreator 5.x. We recommend clearing this check box for round-trip translations and when exporting files to receiving systems that prefer periodic surfaces. Burst Solids and Sheet Bodies into Free Curves (Wireframe)Use this option when the receiving application does not support solid/sheet body entity types or if simple geometry is requested. Export Lines, Arcs and Conics as SplinesWhen checked these wireframe entities are converted to parametric splines. Indicate Exported Geometry Base LocationIf selected, you are prompted to select the origin for the entities to be exported. If cleared, the default origin (0, 0, 0) is used. Export Entities Relative to Active Construction PlaneIf selected, the entities are transformed so they are relative to the active construction plane.
