Compare CAD Input and Output

The native CAD model is imported into HyperMesh and exported using CAD readers in HyperMesh that are run in the background. The exported model is re-imported and overlaid. With superposed models using advanced CAD-CAD comparison, any loss of geometric data is identified, along with any entity changes. A reference report is also created.

1. Click the CAD tab then the CAD IO tab.

2. Select a CAD input file from the first drop-down menu.
   Supported file types include:

   • ACIS
   • CATIA
   • CATIA COMPOSE LINK
   • FiberSim
   • DXF
   • HDF5
   • IGES
   • JT
   • Parasolid
   • PDGS
   • ProE
   • SolidWorks
   • STEP
   • Tribon
   • UG
   • VDAFS
   • HM
3. Select an output file type from the second drop-down menu.
   Supported file types include:

   • IGES
   • FiberSim
   • JT
   • Parasolid
   • CATIA COMPOSE LINK
   • STEP
   • HM
4. Select the HyperWorks version number from the third drop-down menu.
5. Enter a Tolerance value for use in the comparison.
   Tip: Click Native Reader to enable a native reader. Original CAD software and licenses must be used. Only available for the UG format.

   This method of import, along with feature-based meshing technology, provides a robust way to create high-quality CAE solid tetrahedral mesh models without a lot of geometry cleanup.

6. Input files.
   Tip:

   • Click to search for and load additional input files. Select the top level folder to load all files of selected file type.
   • Click in the cell for each file type to activate it. Once the cell is active, click to display the file browser and load only selected files. You can also add multiple files.
   • Click to delete a row from the table.
7. Select an output directory.
8. Click Import/Export to input your source file and output your result information.
   The time and status at import and export for each model file is displayed in the Import Export table. Click Report to see the CAD-CAD comparison report, which is generated for exported and re-imported CAD files.
