Command line
3DORBIT
To choose a parallel or perspective projection in the 3D Orbit view
1 From the View menu, choose 3D Orbit.
2 Right-click in the drawing area, and choose Projection.
3 Choose one of the following options:
■ Parallel. Changes the view so that two parallel lines never converge at
a single point. The shapes in the drawing always remain the same and
do not appear distorted when they are closer. This is the default.
■ Perspective. Changes the view so that all parallel lines converge at one
point. Objects appear to recede into the distance while parts of the
objects appear larger and closer to you. The shapes are somewhat
distorted when the object is very close. This view correlates most
closely to what your eye sees.
A check mark is displayed next to the current projection option.
Note When you exit 3DORBIT, the projection that you choose remains
current. You cannot edit, pick points, zoom, or pan when viewing objects in
perspective projection.
