The tilt of the vector defined by point is a special type of LCS for mesh elements of 2D members. You can define one point in global coordinates and all local x-axis (y-axis) of mesh elements follow this point. It is an analogy to LCS by point for 1D members. This special case is mostly used when you need to add data which are depending on LCS of meshes (e.g. reinforcement, results) and should follow radial layout (Circle slabs, silos, etc…). An example is presented below.
