[-L #] [-R] [-S] [-m1] {objects}
Adds objects to the display list so that they will appear on the MGED
display. The e command is a synonym for draw.
•The -C option provides the user a way to
specify a color that overrides all other color specifications including
combination colors and region-id-based colors.
•The -s option specifies that subtracted
and intersected objects should be drawn with shape lines rather than dot-dash
lines.
•The -A option specifies that the arguments
provided to this command are attribute name/value pairs, and only objects
having the specified attributes and values are to be displayed. The default
(without -o) is that only objects having all the specified attribute
name/value pairs will be displayed.
•The -m1 option will display BOTs shaded if
the display manager is OpenGL and the zbuffer and lighting is enabled. To
enable these settings, from the MGED GUI, choose "Modes/Display
Manager/OpenGL", "Misc/Z-buffer" and "Misc/Lighting".
If the zbuffer and lighting is already enabled, toggle them off then back on
to ensure they are enabled.
•The -L option allows the user to specify a
face count. BoT primitives with more faces than the user set threshold will be
represented in wireframe drawing by their bounding boxes rather than the full
BoT wireframe.
•The -R option tells draw to not change the
view size when drawing new objects. Without this flag, draw will
automatically size the view to make the new object(s) visible when the view
was previously empty.
•The -S option tells draw to be
"simplified" by skipping subtraction objects when drawing, not
drawing NMG interior surfaces, and potentially more. Skipping subtractions is
useful in situations where an object has many large objects subtracted from it
but those objects have relatively minimal impact on the shape. This results in
the default wireframe bearing little resemablance to the evaluated
shape.
The following examples show the use of the draw command to draw
particular objects, to specify color, to draw with shape lines rather than
dot-dash lines, and to limit the objects to be drawn to those having specific
attribute names and value pairs.
Example 1. Draw specific objects in the
MGED display.
mged> draw object1 object2
Object1 and object2 are drawn in the
MGED display.
Example 2. Specify the color used to draw the
object.
mged>draw -C 255/255/255 object2
Object2 is drawn in white.
Example 3. Limit the objects to be drawn to those
having specific attribute names and value pairs.
mged>draw -A -o Comment {First comment} Comment {Second
comment}
Objects having a Comment attribute with a value of either
"First comment" or "Second comment" are drawn.
