Pointsketch er et svært enkelt program å bruke for å teste ut krefter som verker på eit bygg.
pointSketch2D is a program aimed at providing a better understanding of the structural behaviour of two dimensional trusses. The core of the program is a computational engine capable of analysing most aspects of a two-dimensional trusses. A Graphical User Interface (GUI) acts as a layer between the user and the computational engine. The GUI is designed to be as intuitive as possible in order to provide a possibility for the user to freely experiment with the parameters that determine the structural behaviour of trusses.
