stFuncRgn

Works with VSimEM, VSimPD, and VSimMD licenses.

Creates a CSG object based off a STFunc. The boundary of the object is where the function equals zero. Where the function is positive is considered the interior and where the function is negative is the exterior.

<STRgn region>
  kind = stFuncRgn

  <STFunc function>
    kind = expression
    expression = (H(RADIUS-sqrt(x*x+y*y))-0.5)
  </STFunc>
