Polígonos elementales

Funciones poligonales

Dado un conjunto de puntos, puede crear polígonos simples y calcular cantidades geométricas básicas como el área. Para crear polígonos más complejos o acceder a más información geométrica, cree un objeto polyshape. Después, utilice las funciones del objeto para modificar, consultar y visualizar el polígono o el conjunto de polígonos.
