Bent Helix

Recommended Posts

How would you model this in SW?

I did it by sweeping a circle along helix, then bent it with flex.

But the flex distorts the surfaces as you see below:

So is there a better way?

I have never tried Solidworks, but would it not help to first ben the helix, and then to the sweep?

 

Well, it would if it were possible.

But to my knowledge it's not.

Yeah, that's exactly what s/he did.

 

This isn't much help really, but I modeled a similar part in Unigraphics years ago. I did it using math curves. I came up with a formula that created that circular helix, then used it as a sweep path. I haven't used the math functions in SW enough to know whether you could do it that way.

Off the top of my head. Try to model one long spring (around 50 loops). Then use the flex/bend command

 

Thats exactly what I did!

If you read the first post.

Here's a way to model it sweeping, using the twist option, to get a helix around a arc.

 

 

Surf. Sweep with twist along path.

Thats it!

Thanks!

 

Strange how many options can go overlooked.

There is this place where you can find a tutorial on that:

ciao

 

 

Glad someone found the tutorial useful!

 

During the Xmas break, I'll probably get around to making one or a few more. I'll post them here first to get feedback on improving them before posting to my site.

 

Any suggestions for the content of the tutorials? They need to be short and cover specific functionality of SolidWorks due to size of the video files.
