CAD Reader review
A capable free CAD viewer with broad platform coverage and practical drawing tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CAD Reader is a CAD drawing viewer and toolset for construction professionals, estimators, site inspectors, and engineers. It opens DWG and DXF files on Windows, macOS, Android, and iOS, making it suitable for teams that review drawings across desktop and mobile devices. The Free plan includes downloading the product, drawing viewing, and basic functions. Professional adds advanced CAD tools, measurement and annotation features, and CAD editing tools, while Enterprise is available through contact sales.
Its strongest fit is field and review work that requires more than simple file viewing. CAD Reader supports length, area, radius, angle, arc, and continuous measurement, along with drawing markups, comments, cloud lines, leader lines, text, photos, and audio. Layer management and model/layout switching help users navigate drawings, while drawing comparison can support review of changes. These tools give estimators, inspectors, and engineers several ways to record and communicate drawing-level observations.
CAD Reader also extends beyond markup with text and table extraction, Excel export, PDF export with annotations, and CAD entity and text editing. That breadth makes it useful when a team needs to inspect, annotate, compare, extract, and make selected changes within one product. Teams seeking a free viewer with broad platform coverage should consider CAD Reader, particularly when measurement and annotation are central requirements. Users who need advanced CAD capabilities must choose Professional, and organizations looking for an enterprise arrangement should evaluate whether the Enterprise plan matches their purchasing process.
