Hanratty co-designed CAD system, named DAC (Design Automated by Computer) at General Motors Research Laboratories. It was priced at $500,000 per unit (only a very few units were ever sold).ĭr.

Input commands were done with an electronic light pen and a large disk memory device used to refresh the graphic display.Ĭonsequently - Digigraphics division of Control Data Corporation released the first commercially available CAD software system - which was a successor to ITEK's earlier CAD software. ITEK company developed CAD software research system named "The Electronic Drafting Machine" for PDP-1 computer. 20 years later it started to produce well-known AEC system named Allplan. Georg Nemetschek founded his company as a civil engineering office in this year. But still it was not commercial product yet. This is considered to be the first step to CAD industry. Ivan Sutherland (MIT‘s Lincoln Laboratory) developed the program named SKETCHPAD on the TX-2 computer and demonstrated the basic principles feasibility of computer aided engineering drawing. John McCarthy invented the LISP (programming language used in AutoCAD ® until now) 1963 Stromberk Carlson developed a system which interpreted graphics on some kind of tape and output these graphics on screen or printout graphics on special papers. Hanratty (most often referred to as "the father of CAD CAM") developed PRONTO – the first commercial numerical control programming CAM system. The CAD-Earth Registered Version can process any number of points and objects and the images don't have text watermark lines.Dr. Also, all images imported to or exported to Google Earth™ have 'CAD-Earth Demo Version' text watermark lines. Only 10 objects can be imported to or exported to Google Earth. The CAD-Earth Demo Version has a limit of 500 points when importing a terrain mesh from Google Earth. The resulting mesh can be processed to obtain contour lines, dynamic profile and section drawings complete with annotations. Specifying the origin point, rotation angle and distance between rows and columns the mesh density and precision can be adjusted. Terrain Meshes can be created inside an existing closed polyline or along a polyline path calculating point elevations from Google Earth. Screenshots can be also taken in sections to increase final image resolution. Background color can be completely transparent or changed to another color if desired.

Image capture can be in full color, grayscale or B&W in major image formats (BMP, JPEG, TIFF, PNG, GIF). You can also export CAD drawings to Google Earth as image overlays. Placemark name, description, scale and icon can also be set. Curve smoothness can be controlled specifying the maximum segment length and deflection angle. Object line thickness, outline, fill color and opacity can be adjusted. CAD objects like Lines, polylines, arc, circles, points can be exported to Google Earth as polygons, routes or placemarks. A symbol library is included where you can select the placemark block to be inserted or you can add your own blocks. Placemarks can be imported as blocks with elevation, including placemark name and description. Polygons can be imported as 2D or 3D polylines projected to terrain, optionally applying fill color.

You can also import polygons, routes and placemarks from Google Earth to major CAD programs (AutoCAD, ZWCAD+, Bricscad). Image can be clipped inside the closed polyline and joined tiled images can be created to increase image resolution. With CAD-Earth you can quickly and easily import/export images, objects and terrain configurations between Google Earth and major CAD programs.Selecting a closed polyline the corresponding Google Earth image can be imported in full color or grayscale in major image formats (BMP, JPEG, TIFF).
