Procedure :
Step 1: To perform topology on the model as it was having lots of geometrical issues all the single cons,triple cons and unchecked faces were cleared
Step 2: At the edges there were lots of single cons as the model was cut from the center for meshing purpose as the edges were cleared by the same is shown in fig below

Fig.1: Single cons at the Edges of the Model
__
Step 3: For clearing the above single cons new faces were created the edges from faces option in topo module which in turn 100% check geometry

Fig.2:100% check geometry
Step 3: For clearing the above single cons new faces were created the edges from faces option in topo module which in turn 100% check geometry
Step 4: Mid surface was extracted for the model by manual approach and made necessary changes at the damage faces by creating new faces
Step 5:The mid was taken for the model by feature angle selection .
Step 6:The necessary feature where extended and intersected for proper connection which in turn resulted in to triple con

Fig 3: Mid surface

Fig 4 : Dog house elements and curved features resulting into Triple cons
Step 7: Then after Mid Surfacing the model was meshed with the above given quality criteria

Fig 5:Meshing of the Model
Step 8: The meshing was done by spot mesh and Best mesh method
Step 9: After meshing off elements were cleared on the model by Reconstruction-->Split-->Smooth in shell mesh and elements tab
Step 10: The elements at triple cons were not possible to solve hence eliminating those elements

Fig 6: Off elements at tripple Cons

Fig 7: Zero off elements at the Single and Double Cons region
Conclusion: The Model was meshed with the given criteria and higher off elements where found at Cuved features and Tripple Cons
Learning Outcomes: How to check the geometry for the plastic dashboard and properly extracting mid by using various commands and meshing according to the given quality criteria how to clear off elements at curved features
The model solved above is very complicated part in automobile after meshing such model got an confidence to mesh any plastic model
