The creation of a geometry model that approximates the shape of the actual physical problem is the first step before performing any kind of engineering analysis. AndTruss2D offers a built-in model creation system, but it is not quite sophisticated and it is more suitable for editing an existing model.
Also, after trying out some CAD applications for smartphones and tablets I found out that they are less productive and intuitive than their desktop counterparts because of the limited screen sizes, and bescause touch input is not so accurate as mouse+keyboard.
For these reasons AndTruss2D offers 20 truss templates that enable the user to set up a common truss model quickly. However, it is impossible to cover all possible truss geometries with just 20 templates.
