Microspot DWG Viewer is a product based on Microspot MacDraft Professional which enables AutoCAD DWG files produced on a PC to be opened and viewed on Mac OS X. During opening the user can choose the layout that will be opened or open the Model from a list of available layouts. The scale and units can also be chosen or DWG Viewer can do it automatically. The layers in the document can be shown or hidden or grayed and the document marked up by drawing elliptical markers in red and text can be added with a yellow background. The annotation is saved in an annotation layer. The resulting document can be saved as a PDF with the annotations and printed. Zoom tools and a hand tool allow you to enlarge any section of the drawing and scroll around.
