Need Help designing a Flat Screw

[nicolas-regel]

im trying to reversengineer this flat screw with a flat coil. But the flat coil cant be press pulled in the z direktion so the screws Z dosent go throu the cylinder all the way.

Try this:

Another option would be to use the loft command. 

Create sketches for both end profiles (center will be higher).

Create a coil with square or triangular section.

Loft the two end profiles using one edge of the coil as a rail.

thank you for reminding me of the split body function, i used it together with the coild function to create this test piece
