### Parasolid error with surface by formula

Posted:

**Thu Jul 18, 2019 8:33 pm**Hello

I try to make a surface by formula with the following parameters

X(u,v) = 1mm*v

Y(u,v) = when(v*0,2mm*sin(u*1°)>4mm;4mm;when(v*0,2mm*sin(u*1°)<(-4mm);-4mm;v*0,2mm*sin(u*1°)))

Z(u,v) = when(v*0,2mm*cos(u*1°)>4mm;4mm;when(v*0,2mm*cos(u*1°)<(-4mm);-4mm;v*0,2mm*cos(u*1°)))

interval of u (non periodic) 0 to 360

interval of v (non periodic) 10 to 50

I get the error parasolid error: unclassified error.

When I modify the formula vor Z(u,v) and change it into v*0,2mm*cos(u*1°). It sometimes helps but not always.

Can anyone explain what I do wrong?
