Heyy there, 

Im using Inventor 2013 and im trying to make a tapered coil but instead of creating it with a liner taper i want a curved taper. Is there a way to create this (prehaps using guide curves like loft feature?) 

Im new to inventor but have been using solidworks for a while any help would be appreciated.

Edward,

Welcome to the forum.

Have you tried using the coil command under the Model tab?

Hi,

this is an old technique used on other software but works. 3D sketch a helix, 2D sketch a profile shape, surface sweep a line and project the intersect for your new path.

Hope this helps

Cheers

yes, and i have even used the taper bit of that but the problem i have is that it creates a taper that comes out at an exact angle from the origin in a straight line. I need the taper to come out and taper along a curve.

another way of saying it would be that it tapers at 10deg which then gradually decreases to 5deg as the spiral increases.This would create a shape like a flower bud or light bulb.

I will have a go at this later and see if i can get it to work will report back

If you can't get it worked out - attach your attempt here.

im struggling to create the surface sweep. 

If you could make a video, or series of screen shots of the steps it would be brillient  

Thanks Ed.

Do you have an image if what you are trying to model?

Attach something here. Anything you have attempted.

2d sketch

Line
Coil
Surface Output
Pitch and Height (or similar)

exit sketch

3d Sketch

intersection

Sweep

(see attached example)

Ok heres what im trying to create and a how far a can get. Notice how the end tapers out? i want to create that but with much more of curved taper

Im able to create the surface revolve then create a revolved solid but i cant get any of the componants to line up, for example the helix is allways wonky and wont snap to an axis? Also dont understand "3D intersection"
