This paper addresses the problem of constructing a smooth representation of a trimmed surface patch from a given set of unstructured point data measured on the surface patch. Unlike the bottom up approaches reported thus far, the approach described in this paper is similar to the way a trimmed surface would be constructed in a CAD system. The underlying four sided patch is first identified and constructed from the point data and then trimmed with the boundary curves to obtain the trimmed surface patch. The algorithm for identifying the underlying four sided patch is described and results of implementation on typical point data are presented
