each other. You can move and resize drawing objects. You can also divide
a display into layers so that you can segregate various elements. For
example, you might separate HVAC elements from Electrical elements in a
display.
Any of these functions can be performed on a single screen element or
group of them. For information on grouping objects, see Grouping Symbols
(page 210).
Make sure you have selected the item or items with the Build Mode
pointer.
OLE objects behave somewhat differently; their behavior is discussed
under Commands that Ignore OLE Objects (page 293).
Drawing Area
The drawing area of a display is actually much larger than your monitor.
There are scroll bars on the display window for moving around this area.
You should plan to set a few options before you begin drawing:
 Consider turning on snap-to grid and setting the grid size, font style,
and default colors of lines, backgrounds, and fills before you begin. It
is usually easier to work with a grid when laying out a display.
Symbols in your drawing automatically align themselves with the grid
lines or the intersections of grid lines. Grid lines not only make it
easier to place objects in the drawing, but it helps keep the objects
proportional. You can start with one grid size and then modify it as
your work gets more detailed.
 Select a font and font size for any values, trends, or text boxes you
might add to the drawing.
 Select colors for lines, fills, and backgrounds that are easy on the eyes.
For example, if you are projecting on a large video screen, a black
background with colored lines is better, but if you are printing, a white
background is better.
