Bonding components, especially with shells is still troublesome for our customers.

For instance, in welded structures, the designer leaves a small gap between the two bodies for the welds. To bond these properly, the model needs to be modified so the faces are touching.

Additionally, bonding shells in general is not intuitive to the customers (selecting shell edge and shell face, for instance). Also, if the shell geometry is not aligned properly, the bond will not work.
