Mirror Objects Along a Plane
 
 
 

With the Mirror3D method, you can mirror objects along a specified mirroring plane specified by three points.

For more information on mirroring objects in 3D, see “Mirror Objects” in the User's Guide.

Mirror in 3D

This example creates a box in model space. It then mirrors the box about a plane and colors the mirrored box red.

Sub Ch8_MirrorABox3D()
	' Create the box object
	Dim boxObj As Acad3DSolid
	Dim length As Double
	Dim width As Double
	Dim height As Double
	Dim center(0 To 2) As Double
	center(0) = 5#: center(1) = 5#: center(2) = 0
	length = 5#: width = 7: height = 10#


	' Create the box (3DSolid) object in model space
	Set boxObj = ThisDrawing.ModelSpace. _
				AddBox(center, length, width, height)


	' Define the mirroring plane with three points
	Dim mirrorPt1(0 To 2) As Double
	Dim mirrorPt2(0 To 2) As Double
	Dim mirrorPt3(0 To 2) As Double


	mirrorPt1(0) = 1.25: mirrorPt1(1) = 0: mirrorPt1(2) = 0
	mirrorPt2(0) = 1.25: mirrorPt2(1) = 2: mirrorPt2(2) = 0
	mirrorPt3(0) = 1.25: mirrorPt3(1) = 2: mirrorPt3(2) = 2


	' Mirror the box
	Dim mirrorBoxObj As Acad3DSolid
	Set mirrorBoxObj = boxObj.Mirror3D _
				(mirrorPt1, mirrorPt2, mirrorPt3)
	mirrorBoxObj.Color = acRed
	ZoomAll
