Tutorial 3 - Force Distributions

Modifying and controlling the geometry of force diagrams

The third tutorial session presents how to create a force diagram from a form diagram. The initial force diagram is a topologically dual diagram of the form diagram, and the horizontal equilibrium solver is needed to make the corresponding edges of the two diagrams perpendicular to each other, making the two diagrams dual and reciprocal. Additionally, how to modify and constrain the geometry of the force diagram is shown in this tutorial session.

What is covered in this tutorial session:

  • Creating force diagrams from a form diagram

  • Horizontal equilibrium solver and its parameters

  • How to modify and constrain the geometry of the force diagram

Here is the RV2 rui file including an updated toolbar with RV2file_open and RV2file_save_as commands, and a few Patterns that we generated together in Tutorial 2:
