This setting affects files exported both with Trimmed surfaces and with 3D curves. All 2D and 3D sketch entities are included.Įxports using high trim curve accuracy the file size is larger than if the check box is cleared. Includes sketch entities in the exported file. Includes 3D curve features in the exported file. The Surface representation table shows the IGES entity types that compose the trimmed surfaces. Surface representation/System preference The IGES entity types that compose the trimmed surfaces depend on the export format chosen.When you export an assembly as separate files in ALIAS IGES, the origin in the part files is at the coordinates of the assembly origin. If you select both of the above options, the model is exported as both trimmed surfaces and 3D curves. For more information, see the IGES 3D Curves table. Select either B-Splines (Entity type 126) or Parametric Splines (Entity type 112) depending on the entity types required by the target system. Unlike surfaces or faces, you cannot export individually selected model edges to an IGES file. You can also select Bounded Surface (type 143).Ĭonverts the solid body to a 3D wireframe representation in the IGES file. Select Manifold Solid (type 186) to export boundary representation (BREP) data to the IGES file. Select Trimmed Surface (type 144) to convert the faces of the part, assembly, or the selected surfaces to trimmed surfaces in the IGES file. Select from the options described below, then click OK.Įxports the data as solid or surface entities.Select IGES (*.igs) for Save as type, then click Options. The assembly components in the IGES file appear on layers that you can turn on and off in Mastercam ®, or in other applications. You must set the Surface representation/System preference export option to MASTERCAM. The IGES translator supports layers when you export an assembly document as an IGES file.
