(entupd)

(entupd entity-name)


Redraw the entity.


This function redraws the entity on the screen. After you modify a block attribute or polyline vertex, the block or polyline is not updated automatically because recalculating and displaying a multitude of changes might take a long time.

Instead, you force an update of complex entities on the screen after the computations are done using entupd. The entity-name of an entity within the block or polyline updates the whole entity group.

Example

Code Meaning
(setq a (entnext)) Assigns the entity-name to a.
. . . Change entity-see the entmod function.
(entupd a) Regenerates entity group, which contains a.

NOTE You can ensure that all entities on the screen are updated with the (command"regen") function.
