# hey there..!! we have been trying to design a disc.. we are facing a problem in generation of an equation driven curve..

the curve is not being generated from these equations which are in the parametric form.. may i know the procedure to develop it..

it is a equation driven curve.. path for that option is..

tools > sketch entities > equation driven curve (select parametric as the following equations are of that form)

Xt = 2.5*((76*sin(t)-0.7*sin(76*t))+((2*(0.7*sin(76*t)-sin(t))))/(sqrt(1-(1.4*cos(75*t))+0.49)))

Yt = 2.5*((76*cos(t)-0.7*cos(76*t))+((2*(0.7*cos(76*t)-cos(t))))/(sqrt(1-(1.4*cos(75*t))+0.49)))

I guess you know what the equations produce but you do not know how to create a part in Solidworks.
