Running a command like list or properties will display information like the following. However, should a user receive a file with entities created in these products, plain AutoCAD just shows them in a skeletal form or bounding boxes. You can however create those objects using one of the AutoCAD “vertical” applications such as Civil 3D, AutoCAD MEP, or with a 3rd party add-on application such as CADWorx. I recently had a question from a user working on a pipe network drawing, where a file was being viewed but rather than seeing a collection of pipes, just some lines and cross section shapes displayed on screen.ĪutoCAD has native CAD entities that can be created, such as lines, polylines, arcs, circles, splines, text, Mtext, etc, but within vanilla AutoCAD, there is no such entity type as a door, pipe, valve, or topographic surface.
