Means that a feature of size is at the limit of its size tolerance in the direction that leaves the most material on the part. Thus an internal feature of size (e.g., a hole) at its smallest diameter, or an external feature of size (e.g., a flange) at its biggest thickness. The GD&T symbol for MMC is a circled M.
The required sizes of features are conveyed through use of dimensions. Distances may be indicated with either of two standardized forms of dimension: linear and ordinate. With linear dimensions, two parallel lines, called "extension lines," spaced at the distance between two features, are shown at each of the features. A line perpendicular to ...
A parallel is a rectangular block of metal, commonly made from tool steel, stainless steel or cast iron, which has 2, [1] 4 or 6 faces ground or lapped to a precise surface finish.
The structural channel, C-channel or parallel flange channel (PFC), is a type of (usually structural steel) beam, used primarily in building construction and civil engineering. Its cross section consists of a wide "web", usually but not always oriented vertically, and two "flanges" at the top and bottom of the web, only sticking out on one side ...

A house plan [1] is a set of construction or working drawings (sometimes called blueprints) that define all the construction specifications of a residential house such as the dimensions, materials, layouts, installation methods and techniques.
A floor plan is not a top view or bird's-eye view; it is a measured drawing to scale of the layout of a floor in a building. A top view or bird's-eye view does not show an orthogonally projected plane cut at the typical four foot height above the floor level. A floor plan may show any of the following elements: [3] interior walls and hallways ...
A plank is timber that is flat, elongated, and rectangular with parallel faces that are higher and longer than wide. [1] Used primarily in carpentry, planks are critical in the construction of ships, houses, bridges, and many other structures. [2] Planks also serve as supports to form shelves and tables.
