Mechanical Expressions

Explore Geometric Modeling Examples

Mechanical Expressions lets you do sophisticated geometrical modeling and communicate the results as web pages or as mathematics.

approximating circular arcs with spline curves

Approximating Circular Arcs with Cubic Splines

We use the Geometrical modeling capabilities of Mechanical Expressions to find the control points of a cubic spline which approximates a quarter circle.

parametric design

Parametric Design

An app created by Mechanical Expressions lets you alter the angle between cylinders on a 2 cylinder V engine.

cam design

Cam Design

We show you how to model a cam with an oscillating roller follower and a generic follower motion.
