Hello - I was curious if anyone else had the issue I did where I was unable to get the steps to connect to the ground - or actually I could, but it was stretched really far out and teh bottom was not flat. Sorry I did not take a screenshot of that. If the professor follows this discussion I can send my Blender file so you can see what I did wrong. I have two copies of Blender on my machine - 2.78c and 2.79 - and will be redoing sections I have issues with in 2.78c while moving ahead with 2.79. Thanks for any advice.
