How do you make indentations on both sides of a surface?

john_doe639

I'm trying to create a part that will be a flat surface with indentations on both sides. So if you looked at either side, you'd see some bumps and indentations. A bump would correspond with an indentation on the other side.  After a day of trying, I haven't been able to do it.  I found this thread:  https://forum.onshape.com/discussion/10382/indentation but I can't understand how they reached the final product. Could someone give me an outline the steps needed?  I can create the flat surface and extrude it, with holes for where the bump/indentations will be, but I'm stuck at that point.

text-only descriptions of issues don't get a lot of traction here. Got a link to the document or some images to explain? Even bad sketches help a ton.

@john_doe639, are you familiar with the "Rollback Bar" in the feature history of the left side of your part studio window?  Make a copy of the egg carton model that @john_mcclary provided (you listed the url above).  Rollback to the very beginning of the feature history.  Then just step through the feature history line by line.  Interrogate each sketch and feature as you go.
