Parameters
- pointX
- pointY
- pointZ
- geometryFilterFlags
Value Description CAD_ALL_GEOMETRY Test all geometry CAD_CURVE_GEOMETRY Only test curve geometry CAD_POINT_GEOMETRY Only test point geometry CAD_SURFACE_GEOMETRY Only test surface geometry - vectorOption
Value Description CAD_RETURN_NORMAL_TO_CURVES Return the normal to curves or, for surface boundaries, the surface normal. The curve normal is defined as the curve's second derivative vector negated. CAD_RETURN_TANGENT_TO_CURVES Return the tangent to curves (including boundaries). This is the default option. - surfaceBoundaryOption
Value Description CAD_SURFACE_BOUNDARIES For surfaces, constrain the result to the surface boundaries (inner or outer). Does not affect curves. CAD_SURFACE_DEFAULT For surfaces, constrain the result to the surface itself, within the surface boundaries. Does not affect curves. This is the default option. CAD_SURFACE_OUTER_BOUNDARIES For surfaces, constrain the result to the outer surface boundary. Does not affect curves. - pProjectPointX
