Any machine can do the entry stuff. The problem with the $1300 Lenovo or any $1300 machine is that it isn’t good enough to do heavy CAD lifting, but it’s still heavy and expensive. Setting aside the fact that CAD is more satisfying on a desktop due to the value for performance, it can be done and is done even professionally on a laptop, but they need specs way more advanced than you’ll find for $1300. For example, my son’s machine has a quad core i7, quadro 2200, 32g RAM and a 1T SSD. He’s done AutoCAD for an engineering firm and Solidworks at school, but it wasn’t $1300. 
He loves his @Xi, but for the same money he paid he could have had a faster desktop AND a suitible daily driver laptop.
