3.1.12 REBUILD GRAPHICS
The REBUILD GRAPHICS command is used to reconstruct the graphics data for
one or more X-CAD entities.
An X-CAD drawing database consists of two main types of information; entity
data and graphics data. Entity data consists of blocks of information
describing coordinate lists or font data etc. Graphics data describes how
to draw an entity in terms of vectors and polygon data. The graphics data
block for each entity is rebuilt automatically if the entity is edited in
any way. However, there are some circumstances where it may be necessary to
rebuild the graphics information for selected entities. If you redefine a
symbol or a character in a text font, or if a different arc display quality
is selected, the graphics data for any entities that would be affected by
these changes is not automatically updated. The REBUILD GRAPHICS command is
used to modify the graphics data in this type of case.
COMMAND FORMAT
#REBUILD GRAPHICS modifiers [CR]
or
#REBUILD GRAPHICS :Ent x1 x2 ... xn
If the command is terminated with a return bypassing IDENTS, then the
graphics data for the entire database is rebuilt ( unless the CURVEONLY
modifier is used ). Alternatively IDENTS can be used to selectively identify
entities to be processed by the command.
MODIFIERS
CURVEONLY Specifies that only the graphics data for entities that may
contain curve definitions is rebuilt. This modifier is
mainly used if the arc display quality is changed with the
SELECT ENVIRONMENT command.
