AutoSketch uses SKD and SKF, in later versions, as its native format,[citation needed] but can support DWG and DXF.
AutoSketch was developed by Foresight Resources under the name "Drafix" to run under Microsoft DOS, and was one of the first Windows based CAD software products.
One limitation of the first DOS release was that it needed to store all of a drawing in RAM, while editing and could not use any sort of swapping.
[2] In later versions Drafix took advantage of virtual memory available in Windows to edit more complex drawings.
[3] Drafix also took advantage of Windows Object Linking and Embedding (OLE) prior to any Autodesk product.
This allowed Drafix to offer features to help automate reporting such as cost estimation and part list generation.
The illustrated AutoSketch produced drawing, used by UK Advanced Joinery Students in the practical workshop while demonstrating their skills in the manufacture and production of complex frames.
