Helix/Spiral
Helix/Spiral
(OP)
I think I'm loosing it. When I create a helix and use clockwise it looks like a lefthand thread. And when I create a helix and use counterclockwise it looks like a righthand thread. Am I missing something? I just want to create a typical righthand thread.

RE: Helix/Spiral
are you starting at the end of the shaft, or at the termination point of the threads down the shaft? what way you go makes a difference as to Rhand or Lhand spiral.
RE: Helix/Spiral
The CW & CCW notations refer to the direction a point, moving away from the Start Point, travels while creating the helix. Unless the Reverse Direction option is used, the resultant helix direction is not always intuitive.
RE: Helix/Spiral
I have 2 different threads on my part and started the sketch's from 2 different ends from the start of the helix. I think I have it now.
ArtL,
Yeah, doing something like that.

Roll up the feature tree.
Save in a rolled up state.
Right click on the filename and select Send to Compressed (zipped) folder.
Attach the resulting *.zip file here.
Someone will make sure you go down the right (helical) path.

RE: Helix/Spiral
"Clockwise" and "Counterclockwise" refer to the direction that the helix is taking as axial position moves away from the plane of the sketched circle. Nothing to do with LH or RH fastener threads.
The sense of direction for CW/CCW is when looking from the sketch plane's positive normal (i.e. "front face").
