- 7.1.5 ECHO ENTITY
-
-
- The ECHO ENTITY command is used to suppress selectively the graphics display
- for a set of entities or to re-echo the graphics display for all entities.
-
- The command is mainly used prior to plotting where certain entities or types
- of entities are not required for the plot.
-
-
- COMMAND FORMAT
-
- #ECHO ENTITY modifiers [CR]
-
- or
-
- #ECHO ENTITY OFF :Ent x1 x2 ... xn
-
- If the OFF modifier is used, all entities identified via IDENTS will no
- longer be displayed and will remain invisible to IDENTS until re-echoed.
- The remaining modifiers act upon the whole database.
-
-
- MODIFIERS
-
- ALL Will re-echo all entities previously echoed off.
-
- ENTITY The ENTITY modifier is used to enter a further set of three
- modifiers used to toggle selectively the display of specified
- entity types.
-
- .CPOINT Used to toggle the display of cpoint entities. The modifier
- can be followed by one of three keywords:
-
- ON Echo all cpoints on.
-
- OFF Echo all cpoints off.
-
- DOT Echo all cpoints as a dot ( single pixel ).
-
- .TNODE Used to toggle the display of tnode entities. ( As above ).
-
- .SYMORG Used to toggle the display of symbol origins. ( As above ).

- The three entitity types above are generally not required
- on output plots. Any plotting command that drives a pen
- plotter will not plot these entity types anyway, but the
- PLOT RASTER command - used to create raster files for matrix
- plotters - will plot anything that appears on the display so
- it may be necessary to inhibit the display of these entities.
-
- OFF The OFF modifier is used suppress the graphics for any entity
- identified via IDENTS.
