Using the Model Tree in the Navigator
In the beginning, you will probably use the Model Tree mostly as a
selection aid. As you gain more experience, you can use the advanced
options shown in the previous figure that make the Model Tree a
sophisticated tracking and editing tool. Use the Customize dialog box to
move the tree above the graphics area, and add columns to display status
and parameter information. The columns can be used to edit parameters
directly from the column cells.
Multiple Windows and Files in Session
Although more than one window can be open, you can work in only one
window at a time. The window in which you are working is called the
active window. To switch between windows, select from the list of open
windows under Window on the main menu bar. If you switch windows
by any other method, use Window > Activate to activate the window.
Pro/ENGINEER differentiates between a file being open in the sense of
being visible in a window, and in session where the file is in memory but
may or may not be visible in a window. Opening an assembly, for
example, brings all of the associated part files into session. Even though
the associated parts are not open, the assembly references them
continuously in memory.
With two types of open files, there are two methods for closing files. Use
File > Close Window to close the window of a file that is still being
referenced in memory. To remove a file from memory, use File > Erase >
