Procedures

To use Select By Channel:

1. Use Channel Info to store one or more vertex selections in a map channel subcomponent.

   If you’re not sure how to do this, follow these steps:

   1. Select some vertices in the object.
   2. Open the Channel Info utility.
   3. Right-click the vsel (“vertex selection”) channel and choose Copy from the menu.
   4. On the utility dialog toolbar, click the Add button, note the new map channel that’s added, and then click the SubComp button.

      All channels except vsel expand to their three sub-components.

   5. Right-click one of the new channel’s sub-components (say, 2:map:X) and choose Paste.
   6. Use the Channel Name dialog that opens to give the sub-component a meaningful names, such as Lillian Hand.
   7. Continue to make and copy vertex selections and then paste them to different sub-components. If necessary, add more channels to hold different selections.
2. Apply the Select By Channel modifier to the object with the stored vertex selection(s).
3. Choose the selection type.
4. Choose the selection channel.
5. To “bake” the new selection into the object, collapse the stack.
