Wavy swept blend- unable to smooth out.

[jgault]

Hi gang,

I've been having issues with a wavy swept blend and am unable to smooth it out. Creo seems to be creating waves between sections in my swept blend, and the trajectory is straight. Any suggestions or things to try?

Image is attached to show what I'm talking about. If it means anything, the sweep is modeled as one side of the section in line with the trajectory. This side is not wavy- it's the far side of the solid (from the trajectory) that is wavy.

Thanks!
James

Here's an example of the waves between the sections.

That's unfortunately a really cool effect!!!

A model file would help us to determine the cause.  There are several variables that can be set when making a sweep.

Jaime,

You may have too many sections in the swept blend. Remember, your goal is always to create the most robust geometry with the least amount of constrictions. With geometry like the image you have shared, not only are the internal sections important but, the sections at the beginning and end are as well. The "condition", I.E. departure and arrival angles, will affect how the internal flow of swept blend will follow. You may want to create start and end control to help assist the internal flow.
