Introduction & Motivation
Feasibility study
Equilibrium position of pulleys
e.g. on fishery vessels
Automation of complex workflow
Different software: not possible
NX Motion Simulation: possible
Template to guide the user through the workflow
NXOpen as powerful support

Initial Situation: Problems
Feasible result: Tangent wheel surfaces
Wheel always below wire
No intersection with structure
Manually solving constraints mostly results in: Orientation is upside down
Scratching onto surrounding structure

Enhanced Reusable Components by using NXOpen in the Product Template Studio
The usage of Reusable Components increased the productivity of engineers. However, workflows of engineers could still be improved by solving and optimizing relevant modelling data with embedded simulations. The NXOpen Interface gives the possibility to carry out simulations, including pre/post processing, and to display results in a single modelling PTS with just one click.
