ACDBCORE2D_PORT AcDbExtents();
Description
Default constructor. This is typically used to initialize an AcDbExtents object prior to calling getGeomExtents(). It sets the minPoint to a very big value (10 to the 20th power) and the maxPoint to a very small value (minus 10 to the 20th power). Note that at this stage the object is in an invalid state, since its minPoint is bigger than its maxPoint.
