CAD 3D Viewer

CAD files can be opened very easily using an editor, but CAD processors are usually very large and complex applications. If you just want to open a file for preview without making any modifications to it, then it is rather annoying having to wait for it to load in a large CAD application. That is why having a simple CAD preview application might be a good idea. CAD 3D Viewer is one of the software tools you can try out.

Focusing on simplicity, CAD 3D Viewer provides a minimum feature set to allow the quick previewing of CAD files. Speed and ease of use are its utmost advantages, alongside portability.

Due to portability, no installation is required to run CAD 3D Viewer. The application is ready for use as soon as you launch it, allowing you to open a CAD file in seconds. You can use it on the go and run it directly from a removable USB device.

CAD 3D Viewer is fully compatible with some of the most popular file formats, including DWG, DXF, STL, IGES, IGS, STEP, STP, SAT and BREP. As you can see, this list is quite extensive, providing more formats that you might actually expect in such a simple tool.

The main window is overly minimalistic, with a large preview area, a few buttons and no additional menus to deal with. This straightforward look makes this application fit for any type of user.

The available options enable you to toggle the 3D orbit on and off, which is useful if you are loading 3D models. Moreover, there are a few display modes you can choose from, allowing you to load the model in 2D and 3D wireframe, with or without hidden lines, with flat or smooth shading.

CAD 3D Viewer is nothing more than a plain, utterly simple viewer for 3D CAD models. It is compatible with several file formats but that might just not justify the fact that it is a bit pricy for what it offers.
