BIMsurfer vs BIMx Desktop Viewer

BIMsurfer has no write-up on Specifiction yet; its figures are above.

BIMx Desktop Viewer is a free Windows and macOS application for exploring BIMx Hyper-models alongside linked 2D project documentation and embedded BIM data. Markers and hyperlinks connect locations in documents with the 3D model and are created during export. Smart Measure provides length, angle, and area measurements in 2D, plus measurement guides in 3D. Users can export a current layout, an entire layout book, or a 3D view to PDF. Display controls include field of view, perspective or parallel projection, shading, sun position, and anti-aliasing. Hyper-models can be generated in Archicad or DDScad and published locally, to BIMx Model Transfer, BIMcloud, or another location. They can also open in a browser through a web link without installing an app. Graphisoft says BIMx Issues support markup of 2D and 3D views and BCF compliance. Facility managers and owners can access Facilities Management databases through the BIM model. Minimum desktop requirements are 4 GB RAM and 5 GB free disk space; Windows 11 or macOS 10.15 are listed.
