Despite the narrow sidewalks, itâs an attractive, human-scale pattern with many individual buildings, side-by-side, forming a staccato streetwall. By contrast, the mid-rise buildings going up today tend to be on much larger, wider lots.
Using the computer to design objects by modeling their components with real-world behaviors and attributes. Typically specialized for either mechanical design or building design, a parametric modeler is aware of the characteristics of components and the interactions between them. It maintains consistent relationships between elements as the model is manipulated. For example, in a parametric building modeler, if the pitch of the roof is changed, the walls automatically follow the revised roof line.
