Mirroring in 3D Space

The Mirror3D command creates a mirror image in a 3D plane around a 3D axis. Essentially, what is originally visible in this 3D plane is copied in a reverse image on the other side of the axis, similar to the 2D Mirror command.

To mirror entities in 3D space:

1. Type Mirror3D at the command prompt.
2. In the graphics area, select entities to mirror and press Enter.
3. Click in the graphics area or type 3D coordinates to define the three points on the mirror plane, or specify an option:
• 3points: Uses three points to define the mirror plane.
• Entity: Lets you select a planar entity (Circle, Arc, or 2D PolyLine) to define the mirror plane.
• Last: Reuses the mirror plane used in the previous Mirror3D command.
• View: Sets the current viewing plane as the mirror plane by specifying a point through which the viewing plane is supposed to pass.
• XY, YZ, ZX: Defines the mirror plane parallel to the XY-, YY-, or ZX-plane of the coordinate system.
• Z-axis: Determines the mirror plane with two points. The mirror plane passes through the first point and is perpendicular to the line defined by the two points.
4. Specify Yes or No to delete the source entities.
