Thank-you for the info, I guess I should have been more clear.
While I was waiting for a reply I managed to somehow measure the distance between the top outer H (closest to the edge) of case and the bottom D (closest to the edge) of case on the front side, I then somehow was able to select the H and D and move both together until the live measurements were close but not exact.
Then I tried the Back logo and for some reason I cannot repeat measurements of the distances like I did on the front, When I try to measure it just picks a random spot and not where I want like the front. On the front side it allowed me to pick my exact two spot. I think I did something different on the back that is confusing me.
I also noticed that I don't know what Sketch3 is? I deleted it as I though it was not necessary.
I don't know what I'm doing wrong?
I'm so new to this and getting frustrated.
I have attached what I've changed since the first post.
