What are CAD Viewers for Android?

CAD viewers are software tools that enable users to open, view, and interact with CAD (Computer-Aided Design) files without requiring full CAD software for editing or creating designs. These viewers allow users to view 2D and 3D drawings, blueprints, and models in various CAD formats, such as DWG, DXF, or STEP, and often provide features like zooming, rotating, and panning. CAD viewers are commonly used in industries such as engineering, architecture, and manufacturing to review designs, collaborate on projects, and share files with stakeholders. Some CAD viewers also offer markup and annotation tools for commenting on designs. Compare and read user reviews of the best CAD Viewers for Android currently available using the table below.
