Mirror Plane

Duplicate modelling functions use a mirror plane, also called a symmetry plane. You can define the plane on the X, Y, or Z axis, use a stored symmetry plane, or create the plane between two points.

By default, the mirror plane is set to Y=0.

Set the symmetry plane from the Duplicate group on the Common Reference tab.

Define the mirror plane manually

1. Select the X, Y, or Z axis from the dropdown list:

   

2. Enter a value in the adjacent box to specify the plane’s location along the selected axis.

Use a stored symmetry plane

3. Select Stored from the dropdown list:

   

4. Select the name of the stored symmetry plane from the adjacent dropdown list.

   For information on how to create a stored symmetry plane, see Symmetry Plane.

Set the symmetry plane between two points

5. Select Define Between:

   

6. Select the location of the Position to be mirrored the in the 3D view:

   

7. Select the location of the Mirrored position in the 3D view.

   The system places the plane between the two selected points.
