Graphisoft’s BIMx is an interactive app for exploring BIM projects and linked documentation sets created in Archicad, MEP Designer, and DDScad. Please download to visualize or collaborate on architectural design projects on your mobile device(s). BIMx offers professional building visualization with game-like navigation to explore and visualize architectural projects. BIMx features the ‘BIMx hyper-model’ – allowing non-design professionals to explore and fully understand architectural design intent, view project deliverables, and access element-level BIM data. BIMx links the 3D model with the relevant 2D documentation layouts, providing a seamless way to view the 3D cutaway model in the context of a 2D layout — and vice versa. BIMx connects the construction site with the architect’s office for streamlined collaboration. Real-time model cut-throughs, in-context measuring, and project markups in the model context make BIMx your best on-site BIM companion. Drive the design narrative on the building site for fast, specific client feedback. Features: • Hyperlinked 2D & 3D views with interactive markers • Trace 2D drawings on 3D with animation • Access project and building component-related BIM information • Superfast 2D documentation viewer • Game-like 3D navigation • Gravity & Egress recognition • Option to access a Hyper-model element from outside of the app • Google Cardboard VR support on iPhones • Real-time 3D cutaway • Cut Plane Color Picker • Shading options • Shadow casting • Sun positioning by date and time • Measure in 3D and on 2D layouts • Explore 3D models of any size thanks to the streaming 3D engine • Save Favorites • Create compelling presentations • Print support, PDF export • Keyboard, mouse, and gamepad support BIMx Pro features, available with Graphisoft account-based licensing: • Issue creation – BCF-based documentation revisioning • Hide 3D elements and control Layer visibility in the virtual model • Customizable Cut Plane Explore the BIMx Pro features with the built-in demo model.

Deflection Pro is an advanced structural analysis calculator for beam, truss, and frame design. The software is designed to be simple, intuitive, and useful for structural engineers worldwide. Like our other apps, it is designed to run on all your devices. LOAD COMBINATIONS Deflection Pro generates common load combinations based on American and European standards. Simply select a desired design method in the settings page and assign a category to each load. The results are seamlessly aggregated and integrated into the same charts and interface as if you were designing a simple beam case. BEAM COLUMN CAPACITY CHECKS Deflection Pro calculates beam column strength capacity for flexure, shear, tension, and compression based on the AISC specification. The software accurately reproduces tabulated values in steel construction manuals. Flexure Design • Yielding • Lateral torsional buckling • Local buckling • Flange local buckling • Compression flange local buckling • Web local buckling • Compression tee stem local buckling Shear Design • Web shear strength • Web shear strength, considering field action Tension Design • Yielding tensile strength • Rupture tensile strength Compression Design • Flexural buckling • Torsional buckling OTHER FEATURES Since this is our latest and greatest structural analysis app, we are actively improving it and adding new functionality. It receives more frequent updates than other tiers of our software. Other advanced functionality include the ability to directly export to PDF and to save to an external file for backup and sharing.
