Draw a tapered helix. Draw a circle on one and and a point on the other, (or a smaller circle). Then loft from the big circle to the small circle using the helix as the centerline.
Get the helix so both ends are on a plane to give you a ready place to draw the circles.
Awesome snake Mike, where's the head lol
You can also vary the pitch
I think I'd do the head as an elliptical dome and a freeform.
Nothing to add, I just wanted to share a similar project that I completed last week. All modeled in SW with a bit of post processing on the skin.
Awesome work Brian - you need to put that picture in the here
pictures of solidworks projects
this is cool
can a helix be done with an ellipse rather than a circle?
You could draw a 3d spline that does that. You could also scale the snake non-uniform after the loft.
yes any shape, eclipse, hex, triangle......... as long as it's a closed sketch
Yes, as others here have said you could do this as a spline. In this instance I have created a 3-d curve in Excel which is elliptical. I had actually done this before for a previous project and have attached those relevant files.
Saved that as a *.txt file and imported it as a Curve through XYZ points.
Then produce reference planes perpendicular to both endpoints on which you can then sketch the desired end shapes. Finally surface loft between them (I did not try Solid).
This is in SW 2015. Good luck with your project!
Looking for equation-driven surfaces last night, and blundered into this. At first I thought, "How the hell did somebody think of that?". Then I thought, "You'd need a really specific application to use this." Then I thought, "Oh that's a damn good way to make a elliptically coiled snake with just a few mouse clicks."
