Along with clearance, length of overhangs affects the approach and departure angles, which measure the vehicle's ability to overcome steep obstacles and rough terrain.The longer the front overhang, the smaller is the approach angle, and thus lesser the car's ability to climb or descend steep ramps without damaging the front bumpers.

Eaves overhang, shown here with a bracket system of modillions. The eaves are the edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building. The eaves form an overhang to throw water clear of the walls and may be highly decorated as part of an architectural style, such as the Chinese dougong ...
The main platform is defined to have a height of 1,100 mm (43.3 in) at a distance of 1,920 mm (75.6 in) from the center of the track to allow for trains with profile T. Low platforms at a height of 200 mm (7.9 in) may be placed at 1,745 mm (68.7 in) from the center of the track.
As an example, a distance of 1500 millimeters might be denoted by (1500 mm) instead of 1500 mm REF. This implementation has followed in modern CAD software that makes use of parentheses as the default denotation method whenever reference dimensions are "automatically" created by the software. The method for identifying a reference dimension (or ...
Overhangs on two sides of Pennsylvania Dutch barns protect doors, windows, and other lower-level structures. Overhangs on all four sides of barns and larger, older farmhouses are common in Swiss architecture. An overhanging eave is the edge of a roof, protruding outwards from the side of the building, generally to provide weather protection.
The measurement of the difference in elevation between the outer rail and the inner rail is called cant in most countries. Sometime the cant is measured in term of angle instead of height difference. [12] In North America, it is measured in height difference and called crosslevel, even for the curved track.
Checkers, software that analyze CAD data formats, are often employed before and after data translation. The checkers can check the organization and quality of the data against internal company standards and international or industry standards. These checkers can be built into specific CAD packages or work on a number of CAD file formats.
90-foot (27.43 m) radii on the elevated 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge Chicago 'L'. There is no room for longer radii at this cross junction in the northwest corner of the Loop . The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions.
