BIMcollab ZOOM is the latest addition to the BIMcollab ecosystem and brings model viewing and validating fully integrated into the BIMcollab workflow. ZOOM is the best tool to discuss issues in design review meetings within the context of discipline models. ZOOM also helps to analyse data to find design flaws and to verify solutions. Navigation is fast, intuitive and smooth, even with larger models. ZOOM runs both on Windows and MacOS and is the first BIM tool supporting Mac-touch-pad gestures for navigation. Never before it was possible to participate in the BIM data workflow to explore, understand and explain a building this easy.
