You can use HTCH to review architectural drawings, site images, and 3D models directly in your web browser. The tool lets architects, clients, and contractors mark up blueprints, pin comments to exact viewports, and conduct live design reviews without installing heavy desktop software. It supports files like PDFs, OBJ, GLTF, and GLB models, and includes native plugins for SketchUp, Revit, and Rhino. Teams can also use collaborative whiteboards to run meetings, align on changes, and ensure construction teams follow design intents correctly.
