Tips for AutoCAD Reading

Tip: The AutoCAD reader automatically determines whether the file is DWG or DXF and processes it accordingly. Therefore, the same workspace can be used to read either DXF or DWG.

Note: The AutoCAD reader parameters list defaults that will produce the best generic result to any non-AutoCAD destination format, resulting in the best presentation at the cost of some of the original AutoCAD types being lost. For example, blocks and dimensions will be resolved into their component parts. If an AutoCAD-to-AutoCAD translation is desired, the following set of options should be used for best preservation of the original drawing.
