A-Truss3D Pro is a structural analysis and visualization app for 3D truss systems. Create, edit, calculate, and review truss models directly on iPad with an interactive 3D canvas, engineering units, material properties, load cases, and direct stiffness method results.
Design trusses by defining nodes, members, supports, materials, and loads. Visualize geometry, member labels, load arrows, reactions, deformations, dimensions, and force states with clear 3D controls. Review calculated displacements, reactions, member forces, stiffness matrices, equilibrium checks, and summary reports in one workflow.
Key Features
• Interactive 3D truss and double-layer space truss modeling
• Node, member, material, load, and support editing
• Direct stiffness method calculation
• Member force results for tension, compression, and zero-force members
• Node displacement and reaction results
• Deformation visualization
• Stiffness matrix and equilibrium report views
• Custom unit templates and precision settings
• Sample truss catalog for quick starting points
• PDF report generation and preview
• Canvas display controls for labels, dimensions, loads, reactions, font, and scale
A-Truss3D Pro is built for engineering students, educators, and structural professionals who need a focused tool for creating and checking 3D truss behavior.
Start up the app, and all I get is the drawing display. I cannot enter any information. It just ignores me if I tap one of the tabs at the bottom of the screen. According to the App Store, it is supposed to work on this iPad. It does bring up the sample truss. But I cannot get the Nodes, Members, etc., displays to come up with that truss either.
Developer Response
It seems that you are working on landscape mode, just flip your device to portrait and everything will be fine.
• Resize the truss canvas while editing for a more comfortable workspace.
• Adjust diagram height directly in Reports for clearer report previews.
• Improved canvas framing and refined the editing interface.
