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
