Sweep

When I try and sweep or extrude a shape with a heilix for the path the
object rotates 90 degrees?

Yes it does. Don't think there's any way round that one.

 

I thought the sweep command in 2008 worked for that. I know the extrude
continuously rotates.

I made the part in Solid Works or Inventor, converted it to an ACIS file and
imported it into AutoCAD.

I stand corrected. A quick, and slightly unscientific study,
demonstrates that while "extrude" appears to rotate the shape through
90 degrees through the entire length of the path, "sweep" lets you
control the degree or rotation along the path by entering a value
corresponding to the degree of 'twist' along the entire length of the
path. You can simulate "extrude" behaviour by entering a value (+ive
or -negative depending on whether ther the helix is CW or CCW) as the
number of rotations in the helix multiplied by 90 degrees. Not sure
that this does much towards solving your problem, nor that it makes
much sense but hey, I learnt something new.

 

The sat files are posted here. the models are for making a tapped hole in a
model for a 1/4-20 bolt.

From what i saw in the help file the sweep was done in iso view.

Rotation! reading imposes.

Indeed somitimes help file can be helpfull but please take note that the
command sweep has not been used here before.
