Parametric Helix with Variable Pitch

Hello all, I'm newbie. I have a problem to modelling a Parametric Spring with Variable pitch. I will use this spring to be a Deformable Component that I will use in Assy.


Can anyone help me???


Thanks

What do you mean by deformable. Do you just need to design a spring that has parameters and that you can change? Or are you after something else. Let me know and I'll be able to point you in the right direction or send you a part file of a variable spring that I mad that is a family table.


Let me know and i'll get back to you

Sorry for late respond. Yup, I want design a spring with variable pitch (for example, 3 variable pitch. First pitch with 5 turns and 3 units of pitch, Second one with 20 turns and 7 units of pitch, and third one with 5 turns and 3 units of pitch). I want that spring has parameters that I can change, so when I assy in my Assembly files it will be changed to fit the proper length of distance.

Thanks

One way this can be done it by using expressions you could have an if statement to take care of the things you want to controll. The turns and units of pitch. You could make one expression that is the type of spring (1,2,3) for your example


type=1 (5 turns and 3 pitch)


t=if(tpye==1)(5) else t1


t1=if(type==2)(20) else t2


t2=if(tpye==3)(5) else t3


t3=xxxxxxx


p=if(type==1)(3) else p1


p1=if(type==2)(7) else p2


p2=if(type==3)(3) else p3


p3=xxxxxxx


when you define the expressions for the helix you will type in p for pitch and t for turns, and when you change the type # it will change the turns and pitch of the helix.


Hope this helps

Hi Friend,


I cant understand what you said.


how can we custamize helix with this "if" statement?


please tell me instep by step, it will be verry helpfull to me.


THANKS IN ADVANCE
