Hi. Thanks for sharing your work with others. Some constructive [I hope!] comments: (1) Did you teach this before introducing holes? Because using the hole tool for all the features with hole notes would be preferable, right? (2) I really stress geometric constraints, e.g., when specifying the 2 holes on sides and front as a certain distance from the bottom, you may want to make a horizontal constraint, then dimension one. That way, they are always parallel (3) Placing the work-plane on the cylinder at the end...would using "place plane on a surface parallel to a plane" be a better choice? Again, trying to be respectfully constructive. Thanks again for sharing.
