  ) : ITGIS_ShapeAbstract;

Name	Type	Description
_ptg	ITGIS_Point	Reference point in map coordinates.
_prec	double Double	Maximum search distance in map units; distances for points inside polygons are multiplied by 0.95 and point distances are multiplied by 0.9 to prefer points over lines and polygons.
_visible	WordBool	If True, only visible shapes are evaluated; shapes hidden by query or visibility settings are ignored.

Type	Description
ITGIS_ShapeAbstract	Located shape or nil.

To improve performance, use section visibility to choose the layer on which to call Locate. When _visible is True, only visible shapes are evaluated.
