    DWG TrueView
    View and convert 2D and 3D DWG files for free. Open DWG files or convert them to work with older versions of AutoCAD software. DWG is a technology environment that includes the capability to mold, render, draw, annotate, and measure. It is also a reference to .dwg, the native file format for AutoCAD and many other CAD software products. Autodesk created .dwg in 1982 with the very first launch of AutoCAD software. DWG files contain all the information that a user enters in a CAD drawing. This data can include designs, geometric data, maps and photos. The .dwg file format is one of the most used design data formats, found in nearly every design environment.

    GRZ Software

    CNC Software for Non-Machinists. MeshCAM is the fastest way to generate gcode. You have a simple goal, to take a CAD file and get your mill to cut it. You don’t want to become an expert on CAM software, you want parts today. MeshCAM is made for people who just want to make parts now. MeshCAM works with almost every 3D CAD program by opening the two most common 3D file formats, STL and DXF. If you just want to make 2D parts without using a 3D CAD program, you can load 2D DXF files (in R12 format) and extrude them to a 3D part. Sometimes you need a part that cannot be designed with a traditional CAD program. Sometimes you don’t even have a CAD program. If this sounds like you, don’t worry. You can open any image file (JPG, BMP, or PNG) in MeshCAM and the image will be converted to a 3D surface that can be machined directly. Users have come up with incredible uses for this feature to make parts that would be almost impossible with a traditional CAD program.
