In this post, we’ll delve into the world of TRAJPAR. Now I’m not talk’n about some distant galaxy, but rather a somewhat hidden parameter nested inside PTC Creo Parametric modeling software. TRAJPAR is short for Trajectory Parameter. This puppy is one of the advanced modeling goodies that allows you to turbocharge your Variable Section Sweep (VSS). The exciting thing is that with relatively little effort (aside from wading in the waters of mathematical formulas) you can model some amazingly complex shapes that are parametric and robust to-boot!

You may have ridden on Boeing 747. You may have even designed parts of a 747. But have you ever created an entire 3D model of a Boeing 747-8 exterior (including landing gear) in SOLIDWORKS?! Well, one of our favorite Product Designers and SOLIDWORKS trainers, Jan-Willem Zuyderduyn, has introduced a new Boeing 747-8 video course…
