2. Geometric dimensioning and tolerancing - Wikipedia

   en.wikipedia.org/wiki/Geometric_dimensioning_and...

   Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.

3. Engineering fit - Wikipedia

   en.wikipedia.org/wiki/Engineering_fit

   Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.

4. Engineering tolerance - Wikipedia

   en.wikipedia.org/wiki/Engineering_tolerance

   In civil engineering, clearance refers to the difference between the loading gauge and the structure gauge in the case of railroad cars or trams, or the difference between the size of any vehicle and the width/height of doors, the width/height of an overpass or the diameter of a tunnel as well as the air draft under a bridge, the width of a ...

5. Clearance (civil engineering) - Wikipedia

   en.wikipedia.org/wiki/Clearance_(civil_engineering)

   In civil engineering, clearance refers to the difference between the loading gauge and the structure gauge in the case of railroad cars or trams, or the difference between the size of any vehicle and the width/height of doors, the width/height of an overpass or the diameter of a tunnel as well as the air draft under a bridge, the width of a lock or diameter of a tunnel in the case of watercraft.

6. Basic dimension - Wikipedia

   en.wikipedia.org/wiki/Basic_dimension

   In a technical drawing, a basic dimension is a theoretically exact dimension, given from a datum to a feature of interest. In Geometric dimensioning and tolerancing , basic dimensions are defined as a numerical value used to describe the theoretically exact size, profile, orientation or location of a feature or datum target.

7. Toilet (room) - Wikipedia

   en.wikipedia.org/wiki/Toilet_(room)

   These rooms are typically referred to in North America as half-bathrooms (half-baths; half of a whole or full-bathroom) in a private residence. [ 1 ] This room is commonly known as a " bathroom " in American English , a "toilet ", "WC", "lavatory" or "loo" in the United Kingdom and Ireland , a "washroom" in Canadian English , and by many other ...
