Introduction to a line grid

A line grid is a kind of a three dimensional grid. Individual vertices of the grid can be used to define points of the modelled structure.

One can imagine the line grid as a set of wire cubes placed one next to another to create a larger wire cube. The vertices of individual small wire cubes are the vertices of the line grid. What’s more, the cubes may be not only regular cubes, but also other solids like a tetrahedron, irregular hexahedron, etc. The grid may be of either regular or irregular (variable) dimensions in any direction.

The tool is extremely useful for the definition of complex 3D structures on condition that at least some parts of the structure are regular (i.e. of the same spans or of the same height).
