Create a reference vector from a perspective view

1. Choose Utilities > Plug-in Manager.
2. Load the createPerspCameraVector plug-in.
3. Choose Construction > Create Persp Camera Vector.

   Note

   Because the vector is perpendicular to the view, you may need to tumble the view to see the vector.
