Cloning entities
Cloning an entity is similar to copying it, except you draw the new entity with its own geometric values. The entity type and properties (such as layer, color, linetype, lineweight, transparency, thickness) are copied and are the same as the entity that you initially select.
1 Do one of the following to choose Clone ():
On the ribbon, choose Home > Clone (in Draw) or Edit > Clone (in Modify).
On the menu, choose Modify > Clone.
Type addselected or clone and then press Enter.
2 Select the entity that you want to clone. The current properties are set to match the selected entity, and the corresponding entity-creation command starts.
3 Follow the prompts to create a new entity. The prompts vary depending on the type of selected entity.
When the command is finished, properties such as layer, color, etc., are reset to their default values.
