STP Viewer is a versatile 3D file viewer that supports multiple formats including STP/STEP, IGS/IGES, STL, OBJ, SAT, BREP, DWG, and DXF. It features a dynamic 3D section tool, measuring tools, and allows for easy conversion of 3D files to various formats, making it a professional-grade software.

One useful feature of STP Viewer is the Structure panel, which displays the file content and properties of the selected object. Users can control the visibility of 3D model parts and save individual components as DWG or DXF files. Additionally, easy-to-use measuring tools provide detailed information about the 3D model, including its area, distance between points, and radius of a circle or circular arc. Dimension texts can be moved, hidden, or deleted, and the 3D model with all measurements can be easily printed or saved as a BMP file.
Another unique tool in STP Viewer is the 3D section tool, which allows users to create one or more fully customizable section planes. These planes cut a 3D model, enabling users to examine its hidden elements and take precise measurements.
Converting 3D files to different formats, such as STP/STEP, IGS/IGES, STL, DWG, DXF, OBJ, PDF, and JPG, is a seamless process if you're using STP Viewer. What's more, the software supports 2D CAD formats, including DWG, DXF, HPGL, SVG, CGM, and many others.
STP Viewer is a feature-rich software that is reasonably priced and comes with a perpetual license. Its host of tools and capabilities make it an ideal choice for professionals and enthusiasts who need to manage 3D and 2D CAD formats.
