You use local operations when you want to perform operations on certain portions of a multibody model, but not on others.
For example, you design a double-ended measuring cup. You need to shell the two cups and fillet them. However, you do not want to shell the piece that connects the two cups. You can create the part and perform the feature operations on the separate bodies.
To use local operations:
-
When modeling the double ended measuring cups, first create the cups as two separate solid bodies.
- Next, shell each body.
- Model the connection bar and merge bodies.
- Lastly, fillet the edges.
