DXF was introduced in December 1982 as part of AutoCAD 1.0, and was intended to provide an exact representation of the data in the AutoCAD native file format, DWG (Drawing). For many years, Autodesk did not publish specifications, making correct creation of DXF files difficult. Autodesk now publishes the incomplete [3] DXF specifications online.
The drawing was made 130 years after the bridge was built. A linear scale, also called a bar scale, scale bar, graphic scale, or graphical scale, is a means of visually showing the scale of a map, nautical chart, engineering drawing, or architectural drawing. A scale bar is common element of map layouts.
The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale. Thus on an architect's drawing one might read 'one centimeter to one meter', 1:100, 1/100, or 1 / 100 . A bar scale would also normally appear on the drawing. Colon may also be substituted with a specific ...
1:150 1:160: 9 mm (0.354 in) The most popular scale in Japan. For models of Shinkansen high speed trains and other systems using standard gauge track, the international N scale standard ratio of 1:160 is commonly used. TT9: 1:120: 9 mm (0.354 in) Used also in New Zealand. HOn 2 + 1 ⁄ 2: 1:87: 9 mm (0.354 in) Used for 2 ft 6 in (762 mm) narrow ...
DWG is merely descriptive of applicant's goods under Section 2(e)(1) of the Trademark Act for two reasons: (1) DWG is a recognized abbreviation for "drawing," and (2) .dwg is a file format used for computer-aided design (CAD) drawings made both with applicant's CAD software and others' CAD software.

A stamp on the drawing saying "ISSUED" documents that RTP has occurred. RTV: room-temperature vulcanizing; return to vendor: 1. RTV sealants, a way to seal joints. 2.
A graphical or bar scale. A map would also usually give its scale numerically ("1:50,000", for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) A bar scale with the nominal scale expressed as "1:600 000", meaning 1 cm on the map corresponds to 600,000 cm=6 km on the ground.
2mm scale / British N scale railway modeling. 1:150: 2.032 mm: Model railways (Japanese N) Used by Heller for model ships, and proposed by the Japanese to supersede 1:144 scale trains. Models which are commonly made in scale at 1:150 are commercial airliners - such as the Airbus A320, Boeing 777 all the way to the jumbo jets - the Airbus A380 ...
