Paul Sagar: Tips for Creating Spiral Geometry

If you’re new to parametric modeling with PTC products, you may not be familiar with trajpar. Derived from the words “trajectory” and “parameter,” this system parameter can help you create alternating, flaring, bowing, or sinudoidal geometry by controlling the shape along its trajectory.

Last year at PTC Live Global, Paul Sagar, director of product management at PTC, demonstrated how to use the Variable Section Sweep with the trajpar parameter to create a heating coil.

In a four-step process, he defined a revolving ellipse. Next, he defined a helical surface to intersect that ellipse. And then, he trimmed the helical surface with the first surface. Finally, he swept one more surface along the trimmed surface edge to create the proper tube diameter. Confused?  See step-by-step instructions in Sagar’s demonstration video below:
