Using entmake to Build Entities
The entmake function allows you to build an entity by gathering values for things such as coordinate location and orientation, layer, and color into an association list, then asking AutoCAD to build the entity for you. The association list you build for the entmake function looks very much like the association list you get back when you call the entget function. The difference is that entget returns information about an entity, while entmake builds a new entity from raw data.
