B Clears the mged display of any currently displayed objects, then displays the list of objects provided in the parameter list.
`B` -A -o attribute name {value} -s -C#/#/# -R objects

## DESCRIPTION

Clears the mged display of any currently displayed objects, then displays the list of objects provided in the parameter list. Equivalent to the `Z` command followed by the command `draw` <objects>. 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 -A and -o options allow the user to select objects by attribute. The -s option specifies that subtracted and intersected objects should be drawn with solid lines rather than dot-dash lines. The -R option means do not automatically resize the view if no other objects are displayed. See the `draw` command for a detailed description of the options.

## EXAMPLES

The following are run from the MGED command prompt.

Display a named object

mged> `B some_object`

  The display clears, and the object named some_object is displayed.

Draw objects having an attribute with a value

mged> `B -A -o Comment {First comment} Comment {Second comment}`

The display clears, then draws objects that have a "Comment" attribute with a value of either "First comment" or "Second comment."
