Offset

Offset is mainly used to offset surface to mid plane location and to convert the CAD files to .hm format.

Before you begin, it is expected that the BOM or CAD data contains thickness information in order to perform offset. If a thickness value does not exist, you can input a constant thickness for offset.
  1. In the Comparison Browser, right-click and select Comparison/Verification > Offset from the context menu.
    The Offset dialog opens.
  2. Select an Import Type for Base Model.
    • XML (PLMXML or UDMXML)
    • Assembly (CAD assembly files: UG Assembly, CATProduct, JT Assembly…)
    • CAD (Refer Config / CAD section)
    • FE (Not Applicable)
    • Multiple Assembly (Multiple CAD assembly files)
    • Spot Files (Refer Config / FE / Connector section)
    • FE Files (direct file selection)
    • Mixed Import (not applicable)
  3. Select a datatype.
    Respective data types will be listed.
  4. Click the folder icon and navigate to the model to import (Folder/File selections).
    Figure 1.


  5. In the Thickness[%] field, enter the thickness percentage used to offset/move the geometry.
  6. In the Thickness field, enter the constant component thickness in case thickness value does not exist in the CAD data or BOM file.
    Offset distance = 50%*Thickness
  7. Choose a method for running the model.
    • Choose Interactive to run the model in the same HyperMesh session.
    • Choose Background to launch a new HyperMesh session in batch mode.
  8. The Processes drop-down list becomes active when you select the Background option and it also depends on the processor.
    The Model Verification tool launches as many hmbatch processes selected.
    • Choose Check to execute only the comparison without the report generation.
    • Choose Report to generate only the Reports (Check executed previously).
    • Choose Both to perform the comparison report generation sequentially.
  9. Click Run to execute the function.
  10. Click Stop to stop the operation.
    This closes front and background HyperMesh sessions. The browser is populated with offset data in .hm format. The remainder of the check will use these .hm files.
