ANVIL EXPRESS 4.0

Quite simply, ANVIL EXPRESS is the future of mechanical CAD through CAM technology. It has all the tools a designer needs, and it's easy to learn. One of the first industry analysts to review ANVIL EXPRESS was David Weisberg, the publisher of Engineering Automation Report:
The ANVIL EXPRESS Design Drafter module is a full 3-D wireframe design and detail drafting package that includes free-form curves, a comprehensive set of manipulation methods, plus curve and section analysis for basic CAE. And, of course, it supports all popular international drafting standards. Also included is Parametric Drafting, which lets you to apply geometric constraints to the geometry and relational control to the dimensions. Relational technology is particularly useful when multiple designs are based on a parent design (family-of-parts projects) and when a design is frequently adjusted or revised during the course of product development.
