Modelling Plantroom using MEP 2009 on Windows XP machine (32 bit) fault / error code "Coedge on parametric surface with no pcurve". Any ideas?.

Sounds like you got some back geometry.  What parametric objects are you working with?

Parametric Space Curves (Source www.clemson.edu)"The parameter curve (pcurve) is a 2D spline curve in the bi-parametric space of a parametric surface. A
pcurve is attached to each coedge of a face lying on a parametric surface. It is separate from the intersection curve (intcurve) associated with the edge of the coedge, but also approximates the true intersection curve.














Thus, at an edge common to two
faces, each lying on a parametric surface, there is an intersection
curve (a 3D spline in model space) and two
pcurves, one in each of the parametric surfaces."
