To set the first vertex of the metrics

Changes the order of vertices of the objects metrics. Set the new beginning of a digitizing of object. (Appoints the specified vertex as the first one).

For an execution of a mode it is enough to choose object on a map. The choice of object is necessary to do so that the cursor of the mouse was as much as possible close to that vertex of the metrics which must be appointed as the first vertex.

It is usually used in case the image of the first vertex of object differs from the others. For example, if the image of object (house) is set up in such a manner that by semantics in the first vertex its number is signed, by change of the order of priority of vertices (by change of its beginning of a digitizing) it is possible to achieve more correct orientation of the title.
