U,V lying on face

Is there any way to find out whether a U,V parameter lies on the topological face ?

This is required to find the parametric space information .

Hello Mahesh,
try using BRepClass_FaceClassifier with your UV coordinates, if the state is TopAbs_IN, then your coordinates are inside the parametric region of the face.

Good Luck,
