Can a screw auger be made in Inventor (or any other CAD programs)? More specifically, can a section of the helical portion of the screw auger be flatten in Inventor? This is so the amount of sheet material can be determine for an auger of a certain length. (a screw auger has a long helical "blade" welded to a shaft for those that may not be familiar with the term) |

Inventor has an issue with this dilemma when trying to flatten a helix. The true length of the helix line doesn't flatten and offer a circle of the appropriate ID/OD required. I've always used an Excel spreadsheet to calc it for me. When I model it, I just make a coil using the cross section and axis. 3DMAX may have the power to calc but I'm unfamiliar. |

Most 3D packages contain a sheetmetal aspect that is very effective and is used by most manufacturers.To answer your question once you design all components within your model, you can flatten the helical section on its own.However you may need to produce 1 or 2 samples and make adjustments to your model accordingly but that depends on your tolerances.Hope this helps |
