Removing a line under an occurrence group

When working in an occurrence group structure, the Remove Line command can have two different meanings depending on the selected object:

  • Selecting an occurrence directly under an occurrence group The Remove Line command removes the occurrence from that specific occurrence group. The occurrence still remains in the base view. Any other shortcut to this occurrence under another occurrence group is not removed.

  • Selecting an occurrence that is not directly under an occurrence group (that is, a part below an assembly under the occurrence group) The Remove Line command removes the occurrence from its parent assembly. This also affects the base view and any other occurrence group containing this assembly. Moreover, if this occurrence was also directly assigned under an occurrence group, it is automatically removed from that occurrence group.
