Dear All,

How can we make "U" shape spring in nx4?

This can be done with a law curve.
using the following expressions
t=0
a=25
b=50
c=30
ang=180
xt=(a*sin(ang*c*t)+b)*cos(ang*t)
yt=(a*sin(ang*c*t)+b)*sin(ang*t)
zt=a*cos(ang*c*t)
Follow these steps :
1)Enter above expessions using Tools->Expessions , 'c' is number of turns.
2)Inset->Cuve->Law Curve...
Choose 'by equation' option for xt, yt and zt values

Send me a Private Message and I can send you a .prt file with this in it. What version of NX are you using?

Thanks a lot.
I am using nx4
