Sweep with Multiple Profiles

Anonymous
Not applicable

I'm trying to make what I think should be a simple duct part along a three-segment 3d centerline with sharp corners.

The profile is a consistent 10.375in square shape, but in order to constrain the orientation I wanted to give it a profile at the start and end.

I also might want to change out the profile or add one along the 3d sketch.

 

This doesn't seem like it should be that hard. The loft centerline wants a smooth centerline, which doesn't work with my part.

I also want to stay away from frame generator and making a custom content center part just for this if possible.

 

I'm attaching the part.

 

Thanks for your help!

do you want there to be a smooth twist through out the whole part or just the longest center line?

Thank you for the reply!

 

I was hoping the second section (middle area) could be swept more or less normal to the section. I'd like to simulate mitered pieces of straight ducting.

Sweeping it using just the first cross section is close to what I want, but I'd like the end to be rotated to align with the flange, hence the extra cross section.

I don't think that can be done without changing the profiles or twisting.

That's kinda what I wanted to visualize by sweeping the profiles, JD - I want to change them and the dimensions of the start and end sections and come up with a couple different solutions to simplify the geometry as much as possible and keep the twist to a minimum.

 

Thank you very much for the samples, Mwighton, it helps me to see different ways to get IV to do what I'm trying to get it to do.

Similar to @mwighton except I simplified the construction a bit.
