Shadow feature in Pro/Mold

[proengineer]

Friends,
I have an iges file of a Reverse Engineered component which has a surface which is tangent continuous and made in patches as most reverse engineering softwares give as output. Now I have to develop a mold of that component. When I go for creating the Parting Surface using the Shadow Functionality, it does not create the surface.
The problem I feel is due to the bad surface quality, but this is the kind of surface we usually get for a reverse engineered component. Due to the complexity of the surface , I am forced to use only the shadow functionality.

Has anyone faced a similar problem

HI
You may try to use silhouette curve, you may have to sketch some of the curve if it has gabs or overlaps. Then you use the curve for a sweep surface.
