Co to jest Parametric Design in Steel Britiing?

At it core, parametric design estables a set of associative rule that govern thee geometry and behavor of a 3D model. In a steel detail detaming context, this means that every element - columns, beams, brace, bases plates, stigeners, bolt holes, andd welds - is colorn by parameters such as lenguth, anglie, offset, and connection type.
