Regardless of the software you are using, you will want to look
at your 3D models and scenes from every angle, and you will want
to be able to switch between views quickly. 3D software typically
has a large set of tools just for manipulating your view of the
objects you are building. Strata has a particularly good toolset
for adjusting views.
The first thing you will want to do is to split the view window
into multiple views. This makes your model accessible from many
sides simultaneously and gives you an instant feel for where you
are in 3D space at any time. Figure 20-2 shows my favorite view
setup, with a window on the left that is rotated and moved around
freely to see the results of manipulations done in the other
windows, and two windows showing orthographic views (top, right,
left, bottom, front, and back), where the manipulations are
performed. I generally move between views frequently in the right
two windows and frequently change the orientation of the
perspective view on the left.

To split the window into multiple views, use the tiny options
menu button with a little plus sign on it to get the drop-down
menu for that window; then select Split View. To switch between
the different views in each portion of the window, just click on
the name of the current view (for example, Left or Front) in the
upper-left corner of each section of the window to get the drop-
down list of available views.
You can also maximize each view, so that it fills the entire
window designated for viewports within Strata. To do this, click
the little maximize button (it looks similar to the maximize
button in Windows) just to the left of the options menu button.
To go back to split views, click the button again.
The next button to the right of the view drop-down menu in each
section of the window lets you select how the model will be
rendered in that particular window. If you cycle through the
different options with any shape showing in that window, you will
immediately realize the meaning of each, so that a discussion of
each option would be superfluous. I use the GL Flat option as
much as possible. I like this option because it shows both the
general shape of the model and the individual vertices. You can
move between each type of rendering with the hot keys ALT-A
(Point Cloud), ALT-S (Outline), ALT-D (Wire Frame), ALT-F (Flat),
ALT-G (Shaded), and ALT-H (Hidden Line).
The next thing you will want to be able to do with your viewports
is pan, rotate, and zoom. The three topmost tools in the left
column of the toolbar perform these tasks for you. These tools
are intuitive and can hardly be augmented by lengthy discussion
on their operation. You should spend a little time getting
acquainted with these tools before you go too much deeper into
the software.
Finally, note the little slider that is in the middle of the menu
bar on every viewport. It is supposed to be a little eye, but I
thought it was a gear when I first opened Strata. This is a great
tool. It lets you switch between a strictly orthographic view
when the slider is in the left position (good for side, top,
left, views), to a little bit of perspective in the center
position (good for the so-called isometric view), to a wide
perspective in the right position.
