Where can I get the specifications for the case of an apple device?

Question

Do it yourself

good morning
There is an idea to make an interesting custom case (metal bumper) for ipad mini 2 for a loved one. There is no experience in material creativity, there are a couple of familiar engineers who know how to use autocad. The action plan is something like this - make a detailed drawing and order production from a CNC office. (perhaps I will add stages such as product design, printing a prototype on a 3D printer, and after ordering a batch / kickstarter, how will it go)
Where can I get hold of the parameters of the product? Height-length-width is easy to find, technological holes can be measured, you can also find blueprints where all distances are indicated, but how to find (or measure with a tablet on hand) bends, roundings, curvature of the case in order to accurately repeat them in the product?

try to look for a patent for the device. In theory, all the specifications are there.
