Helical Cut

[leggettmatt]

Hello,

I'm trying to perform a helical cut through the length of a tube with a very thing profile. Attached is the sketches I have but when trying to build out the part it won't let me. Some of the information regarding the cut:

Pitch = .1mm
Thickness of cut =.0001"
Length of tube = .6mm
OD=.0255"
ID=.023"

I would like the sketch to have the pitch be parametrically driven by the pitch of the cut if at all possible.

Convert the helix to a 3D sketch entity, and it works fine.

I'm not sure how to do this. I tried selecting the helix and clicking convert entities and it didn't work. I apologize if this is rudimentary, for some reason I don't know this.

Read the Help on making a helix. Once you properly make the helix then you will use it as the path for a swept cut.

Go to Insert>3D Sketch. Select the helix. Convert entities. Exit sketch. Then you can use the 3D sketch as the path for the swept cut.

This is very strange. I've never had to convert a helix to a 3D sketch in order to use it in a sweep. The profile is so tiny that it is causing some weird stuff. If I change the dimension from .0001" to .00041" it works with the existing helix and profile. However, if the profile dimension is .000391" or less it will not work unless the helix is converted to a 3D sketch.
