.CAD File Extension
What is a CAD file?
File created by BobCAD-CAM CAD design products; stores CAD data including the 2D and 3D part geometry and dimensions; used for designing parts and products for manufacturing.
BobCAD-CAM is available in several editions, including Mill, Lathe, BobART, Wire EDM, and CNC Router, WaterJet & Plasma. BobCAD-CAM can import content into CAD files from .SLDPRT, .DWG, .DSF, .3DM, .IGES, .STEP, .STL, .SAT, .X_B, and .X_T files.
NOTE: CAD files are created by BobCAD-CAM version 21 and earlier. Version 22 and later use .BBCD files.
Programs that open CAD files
A CAD file may also be a CAD file created by Autodesk QuickCAD, a CAD 2D vector drawing program that was discontinued in 2004. It contains a technical 2D drawing, which includes geometry and measurement information. CAD files are often used for storing floorplan layouts and mechanical designs.
QuickCAD CAD files are only supported by QuickCAD. In order to open them in another program, the files must be converted to a more widely supported format, such as the AutoCAD Drawing .DWG format or Drawing Exchange .DXF format. Unfortunately, the only program able to convert QuickCAD CAD files is Autodesk QuickCAD, which is no longer developed.
NOTE: Autodesk QuickCAD was originally Softdesk Drafix Quick CAD in the 1990s. But when Softdesk was acquired by Autodesk, Drafix Quick CAD was repackaged as Autodesk QuickCAD, which was developed until version 8 in 2004.
