Publisher's description of Protocase Designer

From Prototocase:

Protocase Designer is free downloadable 3D CAD enclosure design software, that can be learned in minutes, and allows you to design complete custom metal electronics enclosures in less than 20 minutes. You can obtain instant pricing, and order online from Protocase Inc. who will then manufacture your custom enclosure in 2-3 days. Protocase Designer has built-in intelligence that only allows you to design what can be manufactured, so the traditional cycle of design submission and revision is reduced or eliminated. Protocase Designer was developed with the mechanical Engineer in mind to assist in rapidly designing complex electronic enclosures.
