11.1 VERIFY ENTITY
VERIFY ENTITY is used to display database information for selected entities.
The command can be used to obtain information about entities such as
coordinate data, arc parameters, text parameters, layer, depth and viewport.
COMMAND FORMAT
#VERIFY ENTITY [modifiers] [CR]
or
#VERIFY ENTITY INDEX n [modifiers] [CR]
or
#VERIFY ENTITY [modifiers] :Ent x1 x2 ... xn
If the command is terminated with a return, then the entire database is
scanned and listed.
Using the INDEX modifier all an entity to be identified by its index number.
If the command is terminated with a colon, then entities are identified via
IDENTS.
The example below is a typical database listing for an arc entity:
Entity ARC Viewport SHEET
-------------------------------------------------------------------------
Index 1025 (00000401) Type 4 Viewport 0 Layer 0 Depth 3
Flags: visible OFF exclude OFF non-delete OFF IDENTS OFF hilite OFF
Database size 84 Graphics data size 96
-------------------------------------------------------------------------
=== Coordinate list blockID 3 subID 0 length 16
5.177989 4.251153
=== Arc parameters blockID 5 subID 0 length 24
Radius: 5.864300 Start angle: 15.073 End angle: 88.256
Some of the information listed is only of use to programmers.
MODIFIERS
INDEX The INDEX modifier can be used to identify an entity by its
index number. The index number - between 1 and 65535 - should
follow the modifier.
Index number 1 is the drawing itself. This can be verified
to reveal any system parameters saved with the drawing.
Index numbers 2 to 33 are the viewport entities. These can
be examined to list text and dimension parameters etc. Index
number 2 is the sheet viewport.
Index numbers 34 to 1024 are reserved for future use. Actual
entities only start at index 1025.
HEADERONLY If the HEADERONLY modifier is used, then only the header data
for each identified entity is listed.
HEXDUMP The HEXDUMP modifier will cause database information to be
listed in hexidecimal format.
COUNT Count is used to produce a list of the number of each type
of entity in the current drawing.
