To import geometry from Mechanical APDL into ANSYS Workbench, users can utilize a "Command" object to input APDL code directly. The geometry, originally created in the APDL GUI, can be replicated by copying commands from a log file. This method allows for flexibility in modifying geometry and meshing within Workbench. Users are encouraged to consult tutorials on integrating APDL commands into Workbench for guidance. This approach facilitates seamless transitions between the two platforms while maintaining control over geometry changes.
