Question from Anonymous: Can you explain/show how to use the "seed and boundary surfaces" selection tool well?
Answer: Pick any surface included in the selection / shift /boundary surface and let go.
Question from Anonymous: Can you pick more than 1 boundary surface?
Answer: Yes
Question from Anonymous: I apologize for this question not being related to what is being demo'd, but is there a way to select multiple entities without having to hold Control? For example, when picking surfaces for a Copy feature or for a Shrinkwrap, if you have multiple selected, and accidentally select another without holding Control again, you lose everything you've picked up to that point. Is there a collector mode or something?
Answer: This would be combination of seed/bounds and CNTRL for additional selections.
Question from Keith: Once you center button click to place a palette sketch can you ever get back to the interface that shows the rotation and size of that palette sketch?
Question from Kevin: Isn't one of the Intent References all edges of the feature?
Answer: Not really. In the case of extrude, it would be all of the edges in the direction of the extrude. There are other ways to select all edges in a feature (pick box, etc.).
