Returns the name of the next object (entity) in the drawing
(entnext [ename])
Arguments
The name of an existing entity.
Return Values
If entnext is called with no arguments, it returns the entity name of the first nondeleted entity in the database. If an ename argument is supplied to entnext, the function returns the entity name of the first nondeleted entity following ename in the database. If there is no next entity in the database, it returns nil. The entnext function returns both main entities and subentities.
Examples
(setq e1 (entnext)) ; Sets e1 to the name of the first entity in the drawing
(setq e2 (entnext e1)) ; Sets e2 to the name of the entity following e1
Notes
The entities selected by ssget are main entities, not attributes of blocks or vertices of polylines. You can access the internal structure of these complex entities by walking through the subentities with entnext. Once you obtain a subentity's name, you can operate on it like any other entity. If you obtain the name of a subentity with entnext, you can find the parent entity by stepping forward with entnext until a seqend entity is found, then extracting the -2 group from that entity, which is the main entity's name.
