Fin Geometry

[JP_13928769]

Hello,

I am trying to make a fix for a turbine with some complex geometry in Creo 10.0. I don't want to just sketch a shape and extrude it, but rather I am trying to get it to follow a curve. This feels like it should be easy, but I am struggling with it. This is the shape and that is the type of curve I want it to follow. What is the best way to accomplish this.

A variable section sweep will support a varying section and orientation along the sweep trajectory(ies). Without a complete understanding of the required geometry, it is a guess to suggest solutions. You may need to use trajpar in a relation within the VSS (var section sweep) to get the geometry.

This is a video series dealing with VSS feature creation:

Something like this:

A simple sweep following the "spine" curve with a sketch of the cross section. 

Multiple trajectories, relations using trajpar, and swept blend can be used to control angles, rotation, cross section, etc. to get the desired shape depending on your requirements.
