The function
ProGeometryAtPointFind() locates the geometry items that lie on a given point. This function supports solid geometry only.
The function
ProPoint3dOnsurfaceFind() determines if the distance between the specified point and the specified surface is less than the
Creo Parametric model accuracy as set in the current
Creo Parametric session. Accuracy can also be set with function
ProSolidAccuracySet(). This function is applicable to solid and datum surfaces.
The function
ProPoint3dIntoleranceFind() determines if two specified points are co-incident, that is, if the distance between the two points is within the
Creo Parametric tolerance set in
ProSolidToleranceGet().
The function
ProSolidProjectPoint() projects a point along the shortest possible line normal to a surface, finds the point where that line hits the solid, and returns that point. Note that this function works on parts only.
