If a 3D script is run on a mixed model, it will produce many errors and warnings and then finally cease without producing any IGES file.

The 3D scripts work differently by first creating a “surface skin” over the model. Therefore, in the case of 2D mixed models, the user should be aware that a model having mixed element types will only export the deformed geometry for one type of element (i.e., only a portion of the model may be captured in the IGES file). In the case of the 2D coarse macro presented below, the script will only produce an IGES file from the 1st order elements existing in the model likewise for the 2D fine macro, which will only produce an IGES file from the 2nd order elements existing in the model. A given procedure will not work on a mixed model. Each set of commands is presented below (4 total) instructions then follow for using any of them in Mechanical APDL or Workbench Mechanical.ĭisclaimer: The procedures discussed below address 2D and 3D models, having either 1st order elements (no midside nodes) or 2nd order elements (midside nodes), but not a mixture. This article discusses and presents the command language that is available for an analyst to perform the exportation to an Initial Graphics Exchange Specification (IGES) file format, whether on a 2D or 3D model. This can be quite valuable in the sense that it reduces the design cycle, time-to-market, or even costs affiliated with prototyping in a trial-and-error type process. Often times, it is useful to export the deformed geometry from an analysis for further post-processing with perhaps a drafter, another department, or a vendor that will need to design other components to fit in, on, or around the deformed shape (e.g., compressed rubber bushing in a steel housing). This can be accomplished in Mechanical APDL with command language or in Workbench Mechanical via inserted Command Snippets.
