Why More AEC Firms Are Adopting Scan-Based CAD Documentation is a reflection of the industry's growing focus on accuracy, efficiency, and reliable project data. Scan-based documentation captures existing conditions with greater precision, helping AEC teams create dependable CAD drawings for renovation, retrofit, and as-built projects. At BIM Craft Hub, we help transform scan data into accurate, practical CAD documentation that supports better planning, coordination, and project execution.
