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 ŌĆ£Mirror ObjectsŌĆØ 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
```
```End Sub
```
