1.5 Boundary Conditions | Learn About Structures
In two dimensions (2D), each free point on a structure has three different possible DOFs: one horizontal, one vertical, and one rotational. This means that a point can move (translate) in the x-direction and y-direction, or can rotate about the out-of-plane z-axis (equivalent to rotating within the 2D plane).
