A geometric design saved on construction costs and improved visibility with the intention to reduce the likelihood of traffic incidents. The geometric design of roads is the branch of highway engineering concerned with the positioning of the physical elements of the roadway according to standards and constraints. The basic objectives in ...
In geometry, a tetradecagon or tetrakaidecagon or 14-gon is a fourteen-sided polygon. Regular tetradecagon ... {14/6} tetradecagram in the top-right corner, ...
A multiview projection is a type of orthographic projection that shows the object as it looks from the front, right, left, top, bottom, or back (e.g. the primary views), and is typically positioned relative to each other according to the rules of either first-angle or third-angle projection. The origin and vector direction of the projectors ...
CAD: computer-aided design, computer-aided drafting; cadmium [plating]: CAGE: Commercial and Government Entity [code]: A CAGE code is a unique identifier to label an entity (that is, a specific government agency or corporation at a specific site) that is a CDA, ODA, or MFR of the part defined by the drawing.
Example of a non-filleted pole (left) and a filleted pole (right) It is common to find a fillet where two parts are welded together. In mechanical engineering, a fillet (pronounced / ˈ f ɪ l ɪ t /, like "fill it") is a rounding of an interior or exterior corner of a part. An interior or exterior corner, with an angle or type of bevel, is ...
A corner square is a maximal square s in a polygon P such that at least one corner of s overlaps a convex corner of P. For every convex corner, there is exactly one maximal (corner) square covering it, but a single maximal square may cover more than one corner. For every corner, there may by many different maximal rectangles covering it.
Another way isometric projection can be visualized is by considering a view within a cubical room starting in an upper corner and looking towards the opposite, lower corner. The x-axis extends diagonally down and right, the y-axis extends diagonally down and left, and the z-axis is straight up. Depth is also shown by height on the image.
Vertical layout is the track layout on the vertical plane. This can be thought of as the elevation view which is the side view of the track to show track elevation. In track geometry, the vertical layout involves concepts such as crosslevel, cant and gradient.
