Geometrical model creation

Once a weave coding is defined, an analysis of the weave matrix allows answering questions about mutual positions of the yams. Consider a warp yam between two intersections with weft. Which weft yams is it interacting with in these intersections What is its position vis-a-vis these yams An answer to these questions is evident for one-layer weave, but for multilayered weaves it needs analysing the weave code. Knowing these answers allows definition of interactions between warp and weft, which is needed for building a geometrical model of the unit cell based on mechanics of these interactions, and definition of contacts between the yam needed for creation of meso-level FE models. 

A point is defined for the creation of a curve or it is taken from an existing geometric model by picking a point on a graphical screen. When a curve, e.g., a circle, is defined by one or more of its parameters, such as center point and diameter, attribute values are used instead of points.
