What are the two purposes of a section drawing?

They are: 1) To show the alternate position of mating parts. 2) To show the relationship of parts that fit together. 4) To illustrate function of object.

What are section drawings in construction?

Section Drawing Definition Section drawings are a specific type of drawing architects use to illustrate a building or portion of a building. A section is drawn from a vertical plane slicing through a building. This is as if you cut through a space vertically and stood directly in front looking straight at it.

What does a section plan show?

A section drawing is one that shows a vertical cut transecting, typically along a primary axis, an object or building. Both depict a relationship that is not directly perceivable by the human eye, between a building’s mass and the space.

What is section line in drawing?

Section Lines: Used to indicate where the cutting plane cuts the material. Section lines are thin and the symbols (type of lines) are chosen according to the material of the object. Section lines are generally drawn at a 45° angle.

Why are building sections important?

The purpose of a section is to show, graphically, the main volumes of the building and the main building material components. The key to producing a useful section is to “cut” through the most typical building volumes. This helps viewers understand the structure as a whole, and major relationships between spaces.

When should a full section be used?

When a cutting plane line passes entirely through an object, the resulting section is called a full section Fig. 7 illustrates a full section. It is possible to section an object whenever a closer look intentionally is desired. Here is an object sectioned from two different directions.

What are 3 kinds of lines?

In geometry, there are different types of lines such as horizontal and vertical lines, parallel and perpendicular lines.

What is sectional drawing?

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.

What is a template drawing?

A template is simply a drawing whose name ends in the letters DWT, which you use as the starting point for another drawing. When you create a new drawing from a template, AutoCAD makes a copy of the template file and opens the copy in a new window.

What is a sectional view in engineering?

Sectional views reveal hidden details in a mechanical drawing. These views assume that a cutting plane has removed portions of the object represented by the drawing, displaying the appropriate section of the interior. Sectional views are used in engineering and architectural drawings.
