templates for an auger helix

This is my first post here & I am just learning autodesk, so bare with me....



I am working on a project that involves a screw conveyer(auger) with a 3" od, 1.5"/flight and a 0.800" ctr shaft.  I modeled it without any difficulty using the "helix" function in a 3-d sketch & then swept a rectal around that path.  The problem is, I need paper templates to layout the pattern on the steel.  In the past I have made use of the "flat pattern" feature to print paper templates for tube notching and such, but that function prompts me with an error message "no surface to flatten"  Attached is the full screw(augShaft9in.ipt), a single flight and 2/3 of a flight(i dont think a full flight will flatten & not overlap).  if anyone could assist me in getting these patterns printed, it would be greatly appreciated.

Hi mtraven,


If you're cutting single flights, then you might refer to this file:

The file is taken from this thread.


Keep in mind that if you're having a continuous flight made then the process is a bit different. Here's video on


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