\subsection{Convert a curve/line intersection into a two-dimensional curve/origo intersection}

\funclabel{s1327}
\begin{minipg1}
Put the equation of the curve pointed at by pcold
               into two planes given by the point epoint and the normals
               enorm1 and enorm2. The result is an equation where the
               new two-dimensional curve rcnew is to be equal to origo.
