What is a section plane line?

What is a section plane line?

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.

What is a section view on a blueprint?

∎ 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 the section line and the centerline?

Centre lines are drawn to indicate the exact centre of a component being drawn. They are made from a series of lighter long and short dashes. Section lines are special lines placed on a drawing which indicate the area of the drawing through which an imaginary cut has been made to reveal internal details.

What is a full section view?

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

What do section drawings show?

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 parts on a section view are not sectioned hatched )?

Notice that the visible background shapes without hidden lines, appear in each sectional view. To avoid a false impression of thickness and solidity, ribs, webs, gear teeth, and other similar flat features are not sectioned, even though the cutting plane passes along the center plane of the feature.

What are section lines used for?

Section lines are special lines placed on a drawing which indicate the area of the drawing through which an imaginary cut has been made to reveal internal details. These lines are drawn at full density and should be drawn at certain dimensions. Dimension lines are thinner than the lines used to outline a drawing.

What is section line in architecture?

The section line defines the extents of the section to extract from the building model. Section lines are bidirectional and you can specify the length and depth of the section line either visually, using the pointing device, or by entering numeric values.

What are the 7 types of section views?

There are a number of different types of sectional views that can be drawn. A few of the more common ones are: full sections, half sections, broken sections, rotated or revolved sections, removed sections, offset sections, and assembly sections.

What are the names of the sections on a blueprint?

Such sections are labeled SECTION A-A, SECTION B-B, etc., corresponding to the letter designation at the ends of the cutting plane line. Removed sections may be partial sections and are often drawn to a different scale.

What’s the difference between a section and a plan drawing?

Plan, Section, and Elevation are different types of drawings used by architects to graphically represent a building design and construction. A plan drawing is a drawing on a horizontal plane showing a view from above. An Elevation drawing is drawn on a vertical plane showing a vertical depiction. A section drawing is also a vertical depiction

Which is the cutting plane in sectional views?

Sectional views often replace standard views. As figures shown, the cutting plane is a frontal plane and appears as a line in the top view. The arrows at the ends of cutting-plane line point in the direction of sight for front section.

What do the lines in a cutting plane mean?

Various types of section lines may indicate the type of material cut by the cutting plane line. Center lines are used to indicate the centers of holes, arcs, and symmetrical objects. They are very thin (size), long-short-long kinds of lines.
