Creo Parametric Community Challenge 5 - Curves and Sweeps
This month’s challenge is a part design problem based around curves and sweeps:
- Using part modeling features, design a twisted wire pair that passes through at least three non-planar points.
- (Bonus) Using Flat-to-Screen 3D Annotations, create parametric notes so that a user can modify the twisted pair. For example, diameter of the wires or rate of twist (similar to the pitch of a helical sweep). Is your modeling robust enough to handle dimension changes?
- (Extra) Model 2, 3, or 4 twisted pairs that travel along the same trajectory, similar to a CAT6 cable.
- (Super Challenge) Can you make two twisted pairs that twist around each other?
Post a picture or pictures of your work as well as the models. Indicate what version of Creo you used. This challenge is based on a technique I saw in a PTC newsletter 20 years ago, so this can be done using a standard license of Creo (or even Wildfire or Pro/ENGINEER). Note that this is NOT a cabling challenge; you should use part modeling features. However, you may want to consider Multibody Modeling. It’s also perfectly acceptable to perform the challenge in an assembly.
As always, this is a community challenge, so you can build off the work of others. (Please indicate if you have done so.) Also, you may take advantage of any articles in the PTC Knowledge Base or previous community posts.
Have fun!
