sin wave wrapped on a cylinder and then sweep cut

[puppet]

i make a datum curve wrapped on a cylinder 20 diam and 200 long



i make a datum curve with the equation

x = 20 * sin ( t * 360* 10 )

y = t * 200

then create a wrap feature to the cylinder and offset the curve to draw it in the 2d sketcher



but now i can not cut sweep the curve



any ideas how to do this?

use swept blend and sketch same section of the cut at the two ends.

thx for that. but why doesnt just normal sweep work ?

also . if i use a square wave. it will not sweep a square section. but will sweep a round section. i think i will upload the files.

Read the online help for both normal sweep and swept blend to know the limitations of both . I think I should not reproduce the theory behind it as you already have.

The square section on a square wave has the problem of intersection.

Worked for me, if this is what you need. The size of the section caused problems but <1 works for a circular cross section.
