Definition of the part via a 3D CAD model rather than via a 2D engineering drawing. Drawings may be printed (plotted) from the model for reference use, but the model remains the governing legal instrument. MBP: measurement between pins: threads, splines, gears (internal, female) (synonymous with MBW) (see also MOP, MOW) MBW: measurement between ...
The term "feature" implies different meanings in different engineering disciplines. This has resulted in many ambiguous definitions for feature. A feature, in computer-aided design (CAD), usually refers to a region of a part with some interesting geometric or topological properties. [1] These are more precisely called form features.
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing.
The rational model was independently developed by Herbert A. Simon, [16] [17] an American scientist, and two German engineering design theorists, Gerhard Pahl and Wolfgang Beitz. [18] It posits that: Designers attempt to optimize a design candidate for known constraints and objectives. The design process is plan-driven.
Parametric design is a design method in which features, such as building elements and engineering components, are shaped based on algorithmic processes rather than direct manipulation. In this approach, parameters and rules establish the relationship between design intent and design response.

Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering .
The terms computer-aided drafting (CAD) and computer-aided design and drafting (CADD) are also used. [2] Its use in designing electronic systems is known as electronic design automation (EDA). In mechanical design it is known as mechanical design automation (MDA), which includes the process of creating a technical drawing with the use of ...
