VBA:
RetVal = object.AddSolid(Point1, Point2, Point3, Point4)

The objects this method applies to.
Access: Input-only
Type: Variant (three-element array of doubles)
The 3D WCS coordinates specifying the first point.
Access: Input-only
Type: Variant (three-element array of doubles)
The 3D WCS coordinates specifying the second point.
Access: Input-only
Type: Variant (three-element array of doubles)
The 3D WCS coordinates specifying the third point.
Access: Input-only
Type: Variant (three-element array of doubles)
The 3D WCS coordinates specifying the fourth point.
The first two points define one edge of the polygon. The third point is defined diagonally opposite from the second. If the fourth point is set equal to the third point, then a filled triangle is created.
Solids are filled only when the AutoCAD FILLMODE system variable is set to On. To set or query a system variable, use the SetVariable and GetVariable methods, respectively.
