What is a long section drawing?
A ‘section drawing’, ‘section’ or ‘sectional drawing’ shows a view of a structure as though it had been sliced in half or cut along another imaginary plane. Plan drawings are in fact a type of section, but they cut through the building on a horizontal rather than vertical plane.
What is a long section?
A Long Section is a profile view of a surface along a particular route, which plots elevation against the distance along the route. Long sections can be related to each other through Primary and Secondary Alignments. They can also include vertical curves and floating points.
What is a longitudinal section in construction?
A longitudinal section is a section done by a plane along the long axis of a structure. It pertains to a section done by a plane along the long axis of a structure in contrast to a cross-section, which refers to the transverse section.
What is longitudinal drawing?
1 Purpose. 1.1 The ‘Longitudinal Section’ drawing is used to show the vertical relationship between the designed and existing surfaces. The drawing is also used to show the geometric details of the reference string involved. 1.2 For examples of this standard see attached drawings.
What does Section AA mean?
A section removed from its normal projected position in the standard arrangement of views is called a “removed” section. Such sections are labeled SECTION A-A, SECTION B-B, etc., corresponding to the letter designation at the ends of the cutting plane line.
What is a section view drawing?
∎ A section view is a view used on a drawing to. show an area or hidden part of an object by. cutting away or removing some of that object.
What is the difference between cross section and section?
The terms Section and Cross Section might often be used in mathematics or in design. However, the primary difference between the two is that a section refers to the ‘cutting of a solid by or along a plane’, whereas a cross section refers to the surface or the shape that is exposed by cutting through it.
What is Ls and Cs in surveying?
Levelling, Longitudinal Section (LS) & Cross Section (CS): Acquire knowledge on fundamental of levelling, correct methods of spirit levelling and profile levelling, Level Book Keeping and reduction of Level Line by Rise & Fall Method and LS & CS survey along a road.
What is L section and cross section?
In a long section, elevations are determined along a fixed route. Cross Section. Source : https://engineering.purdue.edu/~asm215/topics/proflevl.html. A cross section is a profile view of a surface at right angles to a particular route. e.g. at right angles to a road, river of railway.
What is cross section and longitudinal section?
Longitudinal studies and cross-sectional studies are two different types of research design. In a cross-sectional study you collect data from a population at a specific point in time; in a longitudinal study you repeatedly collect data from the same sample over an extended period of time.
What do you mean by a section drawing?
A section drawing is one that shows a vertical cut transecting, typically along a primary axis, an object or building. The section reveals simultaneously its interior and exterior profiles, the interior space and the material, membrane or wall that separates interior from exterior, providing a view of the object that is not usually seen.
Which is the best definition of a long section?
A Long Section is a profile view of a surface along a particular route, which plots elevation against the distance along the route e.g ground profile along the center line of a road, railway or river. In a long section, elevations are determined along a fixed route.
What’s the difference between an elevation drawing and a section drawing?
A section drawing is a view taken after you ‘slice’ an object, then look at the surface created by the slicing. An elevation drawing is a view taken from a point outside the object without any slicing. In both cases, the object should be standing on its base when the view is taken.
What’s the difference between lateral and longitudinal section drawing?
A longitudinal section drawing is when the cutting plane is along the larger axis of the object. Above is a photograph of St Matthew’s Church at Brixton, UK. A longitudinal section drawing of it is to its right. A lateral section drawing is more correctly termed a transverse section drawing.
