procedure : Open the given IGES file .
1. We have to go for geometrical check up.
2. if any errors are there ansa will notify you .
3. these errors can be rectified by the ansa by selecting all and giving right click in mouse . we will have option of fix .
4. by proceding with fix ansa solves the errors .
5. if any errors we have to do manually .
6. we can use mid surface operation for extraction of mid .
7. ansa is missing some ribs i going to do manully now.
8.create two COG points from any two circles from the parent geomentry.
9.extract the middle surface of the parts by using offset.
10. we can use transform option and rotate that part .
11. we can get mid surface these suface by using offset.
12. we can have a connection between thoose two surfaces by using option { TOPO -> FACES -> NEW -> coons }.
13. we can create the remaining by using these similarly either middle or offset.
14. for ribs we have to extend thoose ribs up to the surface.
15. we can achive mid surface manual for all the surfaces.
results:- maual mid surface is giving some what good feature capturing then the auto mid surface.
