3d intersection between helix surface and extuded surface

then sweep

attach your attempt here for further instruction.

 

I recommend that your teacher go through ALL of the tutorials/papers in my signature and especially the Knot tutorial.

Hi caleb.leftwich93, 

 

Here's an example file that you can look at to see how it's done.

 

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

Here is another example with subtle differences - the key difference is the swept circle is on a plane perpendicular to the start point of the path to ensure the wire cross section is round.

 

The example isn't perfect using this helxi intersection method - but should be close enough.
If you need closer to perfect - post back and someone will suggest a slightly different intersection for the path.

Re: Making a rectangular spring

I know this is an old thread but I am drawing basically the same thing right now and am having some problems.

 

I used the file you posted but your lines are not straight. All of the lines going vertically (they are slanted I know, but essentially vertical) are bent in the middle instead of being straight. Is there a way to correct this?

 

Thank you.

If I use a small pitch the transition between bends is straight but if I stretch the pitch out, it distorts the wire.

I attached an example with straight lines - but you did not indicate in your problem description that you are using an older version of Inventor.
