Hi how,

I had a go at the ipad a little while back, not to do the whole model but to see what technique I would use with MoI for the back, I got the engineering drawing from exactly where ycarry mentions from apple as a PDF and imported it into MoI (with Michaels help because....).

If you open the attachment it's self explanatory, you'll see that for symmetrical parts I work on one half or in this case one quadrant, when done and satisfied just use mirror to complete the rest of the model.

Hope this helps, any questions feel free.

Cheers
