The AutoCAD reader and writer use symbolic names for the different entity types stored within a drawing file. This simplifies feature type specification.
The following table gives a brief description of each of the different AutoCAD entity types currently supported by the reader and/or writer. The entities are described in detail in the Feature Representation sections.
| FME autocad_entity | Description | 
|---|---|
| autocad_line | Linear features stored within drawing file as a line or unclosed polyline. | 
| autocad_point | Point features. | 
| autocad_xline | Linear features of type xline. | 
| autocad_ellipse | Features with an elliptical or circular representation. | 
| autocad_shape | Features whose representation is stored in an AutoCAD shape file. | 
| autocad_polygon | Features whose geometry is represented by a closed polyline. | 
| autocad_face | Features represented by a 3D face object. The face object may have 3 or 4 coordinates. | 
| autocad_arc | Features whose geometry represents a portion of a circular arc. | 
| autocad_trace | Features with a 4 coordinate trace geometry. | 
| autocad_solid | Features with a 3 or 4 coordinate solid geometry. | 
| autocad_ray | Features with a linear geometry which represents a ray. | 
| autocad_text | Text features. | 
| autocad_spline | Spline features. | 
| autocad_multi_text | Text features that store multiple lines of text. R14 and later only. | 
| autocad_multi_line | A linear feature that is represented by two or more parallel lines. Note  R14 and later only. This is supported only by the Reader. | 
| autocad_insert | Point features that represent the location of a block reference entity. | 
| autocad_leader | AutoCAD Leader entity representing leader lines in drawings. | 
| autocad_hatch | Features with 2D boundary loops which form polygons and donuts, and which may be filled with line patterns or color gradients. | 
| autocad_mpolygon | Features with 2D polyline loops which form polygons and donuts and which may be filled with line patterns or color gradients. | 
| autocad_surface | Features with connected and unconnected planar and non-planar 3D areas that may represent meshes or the boundary representations of 3D solids. | 
| autocad_solid3d | Features with connected and unconnected 3D geometries that may be 3D solids or their closed boundary representations. | 
| autocad_attr_def | Features without geometry that contain information about AutoCAD attribute definition. Main information on features would be the Tag, Prompt and Default value for that attribute definition. | 
| autocad_dimension | Features of various dimension types which contain an aggregation of geometries such as text, lines, arcs or points. | 
| autocad_dimension_def | Features without geometry that contain information about AutoCAD dimension entities. These represent the original attribution of dimensions which have had their geometry resolved into separate features. | 
| autocad_multi_leader | AutoCAD Multi-Leader entity representing multiple leader lines in drawings. | 
| autocad_raster | Rectangular features that contain raster information. | 
| autocad_xref | Features with point geometry that represent the locations of reference entities which are associated with External References. | 
| autocad_info | Features without geometry that contain information about certain AutoCAD System Variables stored within the drawing. | 
| autocad_viewport | Rectangular features that represent a viewport within a paper space. | 
| autocad_wipeout | Polygon features that represent a wipeout. |
