projected curve with pitch value

[satish]

Is there any option to create a Helical curve, with pitch value

by the time that curve should be projected on the Round bottle?If possible Means Please explain me Briefley. With a best example.My aim is to project a curve on a Round bottle with a pitch value.reply to this E-mail id: satishkumar@iffco.com

yes,



if you want only a curve (helical) then chose datum curve by equation (... cilindrical)

if you want a shape (portrusion or cut or surf) then chose /adv/helical sweep

Hi dude



Use cartesian type

Write this equation

x = 2 * cos ( t * 360 * 4 )

y = 2 * sin ( t * 360* 4 )

z = t * 3



add 3 last lines

the number 2 representing the radius off the spiral

the number 3 pitch

the number 4 number off coils
