procedure:-
given component is a trimed portion of a dashboard .
1. we have to check the geomentry first .
2. we have to clear this geometrical errors . By giving topo it will stich the all edges .
3.after clearing all the geometrical errors .
4.now we can start creating the mid surface for these component .
5. We have to find out the thickness of the component first . the thickness for the base is .6 units.
6. i will select the faces which are not having ribs first and offset them with a distace of .3 units .
7. now we have to work on the rib areas . let as start from any of the side .
8. we are giong to take mid for these ribs . we have to extract two middle cruves one at the top edges and the other curve at the connection area. {TOPO -> CURVES -> MIDDLE }
9. the bottom curve should be projected to the down surface . {TOPO-> CONS -> PROJECT}
10. now we can create a new surface by using coons option by using the top curve and project con.{TOPO->CONS->NEW->COONS}
11.similarly we can capture all remaining ribs in these manner.
12. meshing is to be done for the completed mid surface .
13. we have to assign the thickness for the mid surface after completing the the whole mesh .
Result:- we will know how to do mesh for the varying thickness component in this project.
