Create Solid-Filled Areas

You can create triangular and quadrilateral areas filled with a color. For quicker results, create these areas with the FILLMODE system variable off, then turn FILLMODE on to fill the finished area.

When you create a quadrilateral solid-filled area, the sequence of the third and fourth points determines its shape. Compare the following illustrations:

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.

To create a solid-filled area, use the AddSolid method.

For more information about filling solids, see “Create Solid-Filled Areas” in the User's Guide.

Create a solid-filled object

The following code example creates a quadrilateral solid in model space using the coordinates (0, 0, 0), (5, 0, 0), (5, 8, 0), and (0, 8, 0).

Sub Ch4_CreateSolid()
	Dim solidObj As AcadSolid
	Dim point1(0 To 2) As Double
	Dim point2(0 To 2) As Double
	Dim point3(0 To 2) As Double
	Dim point4(0 To 2) As Double

	' Define the solid
	point1(0) = 0#: point1(1) = 0#: point1(2) = 0#
	point2(0) = 5#: point2(1) = 0#: point2(2) = 0#
	point3(0) = 5#: point3(1) = 8#: point3(2) = 0#
	point4(0) = 0#: point4(1) = 8#: point4(2) = 0#
	' Create the solid object in model space
	Set solidObj = ThisDrawing.ModelSpace.AddSolid _
				 (point1, point2, point3, point4)
End Sub
