Hello all,
I have been reading a lot on hybrid modeling in several forums, but until now I still have not found any satisfacory answer to the question wether or not to enable hybrid modeling. I have been using Catia V5 since release R3 and I have allways been designing parts without hybrid modeling enabled. The rational behind it is that I use a start model which is logically ordered. By that I mean that geometrical sets are ordered in such a way that it follows the manufacturing steps of a part in real life. Another reason for me not to use Hybrid modeling is that a Part Body is a solid feature, wireframe and surface geometry are to be placed in geometrical sets, hench the name. Allmost all automotive OEM's prohibit the use of Hybrid modeling, there must be a reason for it which no one has been able to explain to me yet, even consultancies. The discussion I would like to start here is not a yes/no discussion but rather one based on facts. Since I have to deal with very stubern engineering partners dayly who insist on hybrid modeling I am interested to know more about the following:
1. what are the effects of mixing hybrid and non hybrid parts in one assembly? especially large assemblies?
2. what are the effects to engineers who have hybrid modeling turned off when they have to modify a part?
3. what are the effects of hybrid modeling to mass calculations?
4. what are the effects of hybrid modeling to a PLM system like Smarteam?
5. what are the effects to the file sizes when hybrid modeling is used to design a part?
6. what are the effects to element sharing through publications or through paste/as result?
7. does hybrid modeling oppose difficulties for the manufacturing process, for instance, some features need to be deactivated (machining opperations on a casting)?
If there are more issues which we could disscuss then please bring them up, lets share our experiences on this!!!!
I hope to have a good debate on this subject, thanks in advance for those who will contribute.
