Duplicating and Mirroring Objects
To duplicate and mirror an object about a plane, use the Edit> Duplicate> Mirror command. The plane is selected by defining a point on the plane and a normal point. This command allows you to duplicate an object and specify the duplicate's position.
This command is similar to Edit> Arrange> Mirror, except that this command duplicates an object, rather than moves it.
- Select the object you want to mirror.
- From the menu bar, click Edit> Duplicate> Mirror or, on the Draw ribbon tab, click the Thru Mirror (Mirror Duplicate) icon:
- Select a point on the plane on which you want to mirror the object.
A line drawn from this point to the mirror plane will be perpendicular to the plane. The distance between the point on mirror plane and point along the normal does not matter; only the vector direction matters
- Select a normal point on the plane in one of the following ways:
- Click the point.
- Type the coordinates of a point relative to the first point in the dX, dY, and dZ boxes, where d is the distance from the previously selected point.
A duplicate of the object appears on the plane you specified, oriented according to the normal point you specified.
