What's the difference of Multi-body strategy between Catia, Creo, NX and SW?

PTC provided multi-body concepts from Creo Parametric 7.0 and it looks more like Catia's multi-body strategy than SW or NX, but other behaviours looks like SW/NX such as operating boolean or fillet, chamfer, e.g.

  1. Catia: 

    1.1. All features not only boolean operatings can only be applied on actived part-body;

    1.2. Part-body needs to be created before any features founded in Catia, more than 1 splitting solid can be contained in each part-body.

  2. SW & NX: 

    2.1. Creat boolean operatings and then choose which body we wanna apply, other features can be directely applied on the body without active(None active concept to be exact) ;

    2.2. Automatically creat 1 body per splitting solid that we can't choose how many splitting solids 1 body can hold.

  3. Creo: 

    3.1. Creat boolean operatings and then choose which body we wanna apply, other features can be directely applied on the body without active(None active concept to be exact) ;

    3.2. Part-body can be created before or after any features founded, more than 1 splitting solid can be contained in each part-body.

I am considering why they chose such completely different strategy especially for QTY. of splitting solids in a part-body. Is there any congenital limitations for those 4 applications make this difference?

Creo, especially from version 7.0 onwards implemented a hybrid approach that borrows from both Catia and SW/NX philosophies:


Flexible body creation in Creo allows more than one splitting solid in a part-body, similar to Catia. You can create bodies before or after features, giving the user control over the structure. You can also export bodies as parts with automatic reference update control.

Got it, Creo implemented multi-body approach late so it absorbed others successful experience, that explains my cofusion.

 

Thank you very much Micheal

    3.1. Creat boolean operatings and then choose which body we wanna apply, other features can be directely applied on the body without active(None active concept to be exact) - Part body in Creo can be actived, Red description is not corect, ignore it ^_^;
