Here is an object sectioned from two different directions. Section lines are evenly. Full sections half sections broken sections rotated.

Full section in a full section the cutting plane line passes fully through the part. There are three major types of sections used in engineering drawing. A section is used to show the detail of a component or an assembly on a particular plane which is known as the cutting plane.

If the cutting plane cuts halfway through the object it is a half section. The section-lined areas are those portions that have been in actual contact with the cutting-plane. Sectional views in engineering technical drawings Half Sectional views.

A cutting plane line shows where object was cut to obtain the section view. There are three major types of sections used in engineering drawing. Sectional views are used in technical drawing to expose internal surfaces.

There is no cutting plane line. 6 Types of sectional views Full sections. What is Full Section.

A simple bracket is shown in Fig. Section drawings are orthographic projections with the exception of section perspectives. A cutting plane does not necessarily need to cut the whole object.

What is Half Section. Lines used in section views. They serve to present additional orthographic views of surfaces.

As mentioned above A section drawing is a view taken after you slice an object then look at the surface created by the slicing. Haitem Hichri Section Views What is a section view. Engineering Graphics with AutoCAD 2011 1e James Bethune.

Section Callout or Blow Up Section. Last Updated on Sat 23 Oct 2021 Engineering Drawing. The cutting-plane line cuts halfway through the part and removes one quarter of the material.

81 and it is required to draw three sectional viewsAssume that you had a bracket and cut it with a hacksaw along the line marked B-B. This means they are not drawn in perspective and there is no foreshortening. K half section The view Obtained When the cutting plane goes half way across the Object to the centre line.

Types of Section in Engineering Drawing. Section lines are used to define areas that represent where solid material has been cut in a sectional view. Normally a view is replaced with the full section view.

If the cutting plane-line cuts entirely across the object it is called a full section. There are different types of section drawings. Dimensioning to dotted lines is not a recommended practice.

Used to show where the object is being cut. A revolving view is effective for elongated objects or. Partial or Broken Out Section 4.

Broken crosshatching shows where cutting plane line intersections material each material has its own crosshatching cutting plane line shows where the imaginery knife cuts thru the part line is always parallel to a line of rotation shows which cutting plane line goes to the section. Figure 20 - Front view and half section. A detail drawing magnifies a specific part of a larger drawingThe specific part is often too small to be clearly seen in the larger drawing hence the need for spot magnification A detail drawing is a view of a specific part of the complex drawing.

There are a number of different types of sectional views that can be drawn. You have learned that when making a multiview sketch hidden edges and surfaces are usually shown with hidden dash lines.
