Cannot enter any data

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.

FAQ

What is A-Truss 3D used for?

A-Truss 3D is a specialized application for structural engineers and students to analyze space trusses. It calculates node displacements, member axial forces, and stress using the Stiffness Matrix Method.

How does A-Truss 3D help with complex trusses?

The Truss Assistant Creator in A-Truss 3D simplifies the input for large and complex trusses by automatically generating data from minimal information, reducing manual input errors.

What kind of output does A-Truss 3D provide?

The app provides detailed calculation results, including node displacements, member axial forces, and stress. These results can be exported as PDF files for printing and sharing via email.

Can A-Truss 3D handle very large truss models?

Yes, A-Truss 3D has been tested on older devices with large space trusses, such as one with 145 nodes and 512 members, without encountering issues.

What are the viewing options in A-Truss 3D?

Users can view their truss models in three ways: Proportion (members drawn to scale), Equal (all members same size), and Wireframe (ideal for complex models).

What is the price of A-Truss 3D?

A-Truss 3D is a paid application, available for $3.99.

On which devices can I use A-Truss 3D?

A-Truss 3D is currently supported on iPads.
