Field is very similar to Auto Text in MS Word. If you are familiar with MS Word Auto Text, you would easily be able to pick it up in ZWCAD. By using the Field command, you can update or change the text in the drawing during the life cycle of the drawing.
By using Qselect command in ZWCAD, it provides a method to list the object type and property which meet a list of selection criteria and jobs will be completed which meet the criteria specified by the options.
ZWCAD emphasizes such features as faster speed, DWG file format support, efficient drawing features, and powerful APIs. For this whitepaper, Ralph Grabowski tested two of the claims: DWG 2010 support and Windows 7 compatibility.
