iPad Screenshots


The easy and fastest way to analyze the 2D-Truss problem now available in iPad. This version is tailored specifically for the iPad device.

• Standard Truss Templates: with the standard truss template (19 types of truss for initial version) , you can easily create and config your truss as required.

• "Custom Truss"; If the built-in standard truss template doesn't match your requirement, "Custom" your own Truss is also easy to create due to the Node & Element generating features.

• Unit Flexibility: very flexible in Units system, you can choose any units at your convenience without the requirement to restart the application and the unit system is saved per your truss's project. For example you use m. as node coordinations while you choose mm. for the deflection of the nodes or you can even choose in. or ft. for nodes's deflection (if you really need).

• PDF Reporting: All result information of your truss are shown in PDF and also you can email this result.

Does not work

This would be a great application if it worked. It provides no moments in members, crashes frequently, limited constraints, has limited results. I have no idea what this ap is good for if you can't constrain nodes or calculate moments

Not so hot

Too much bla, bla and not enough information about the app use. Very difficult to edit the information. It is not possible to get out of edit mode when using the calculator, must use the iPad exit button since there's no way of returning to the working model. A very poor program, certenly not worth the 10 bucks

A-Truss HD

The setup of a truss was fairly easy once you get the hang of the quirky approach required.

I have three hangups with this app.

First, and this is the most serious. You can't create a new truss by copying an existing truss and then modify it. Trying different design variations of a concept is what structural design is all about.

Second, the available units needs to include Kips and Kips/sq-in.

Third, there does not seem to be any way to add section properties from another country than the South Africa default.

Without these capabilities A-Truss is $9.99 toy rather than an engineering tool.
