Automation of the repetitive tasks in Hypermesh
Geometry input from Pro/e
• Eliminating fittings from the Pro/e geometry
• Generating and cleaning middle surfaces
• Connecting pipe mesh to the base panel of the chassis
Routing of the pipe centerlines based on existing photo documentation
• Simple routing between two points
• Modification of existing centerlines
• Step by step routing
In both cases
• Importing device mass and inertia data from Pro/e export file
