Resizable components are the core of Prinect's parametric design technology letting you create a resizable structure, and then, by just editing necessary parameters, prodice multiple variants of the same structure, without any additional drawing. In that sense, resizble components are "live" — when in a structure you change components' parameter expressions, the components take into account the geometric relations between the structure's objects, and turn the original structure into a new, differently sized structure with identical geometry.
The resizable components that you can create in EngView are:
