Reflection in 3D Mode
The Reflection tool can be used to reflect the drawing that has been loaded along a selected coordinate system axis. Click on the reflection tool and then on one of the X, Y or Z axes with the arrow cursor. The drawing is reflected along the selected axis.
Once you have activated the Reflection tool, you can switch to the arrow cursor temporarily by pressing the CTRL key.
If you now want to reflect the assemblies along another axis, click the axis in question and repeat the reflection procedure described above.
