I will agree that copy and past works if you are filling the entire sheet with the same part. Due to material cost and better efficiently it’s better to nest all required like material parts for any given day and only produce what is needed.
I took the time to do a study on hand nesting or software generated nesting and found out some interesting things that may very depending on your product mix. If an order was for more than 25 with a mix of 30 different types of parts I could justify hand nesting to save material and cycle time. Anything less than 25 I could not justify my time to manual build the nests.
