Why should you follow these rules?
These certain patent illustration rules, set by the USPTO, should be strictly adhered to. It is so because patent drawings (or illustrations) describe and demonstrate the invention with great accuracy and simplicity.
They also increase the chance of your patent application getting accepted. And hence, for the same reason, it is mandatory to attach at least one patent drawing with your non-provisional patent application.

Hire a Draftsman or Do It Yourself?
Hiring a draftsperson or doing it on your own, both have their own boons and banes.
By vigilantly following the Patent Illustration Needs, you can definitely make drawings of your invention all by yourself. The drawings can be made using pen-and-paper or using patent drawing software like Computer-Aided Design (CAD). One of the major benefits of making drawings on your own is that you are well aware of even the minutest detail of your invention.
It also saves you from spending money on hiring a professional.
However, if you lack skill, have no patience, and do not want additional pressure on your mind, then a professional draftsperson can prove to be an asset.
