Sectional views are used in technical drawing to expose internal surfaces. Full section The view obtained even the cutting plane is right across the object.

Engineering Drawings

Figure 19 - Full and sectioned isometric views.

. Half View Shows only the portion of the model on one side of a datum plane. 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. There are three major types of sections used in engineering drawing.

An Elevation drawing is drawn on a vertical plane showing a vertical depiction. Section lines are used to indicate where the cutting plane cuts the material. In this view the cutting plane is assumed to bend at a right angle and cuts through only half of the.

When specific features of an object that need highlighting are not located. Types of Sectional Views Full Section. Projected View An orthographic or isometric.

A cutting plane line shows where object was cut to obtain the section view. They serve to present additional orthographic views of surfaces. This is a convenient convention to use on single view drawings because the shape could not be confirmed without projecting a second view or an added note.

Full View Shows the entire model. 89 shows a case where it is required to indicate details on two separate intersecting planes. You select the orientation of the view when you create it.

The diagonal lines on the section drawing are used to indicate the area that has been theoretically cut. Section lines are used to define areas that represent where solid material has been cut in a sectional view. Figure 20 - Front view and half section.

The line that separates the different types interior and exterior may be a. The default orientations are based on the origin in the digital prototype. A few of the more common ones are.

A revolving view is effective for elongated objects or. The three main types of pictorial drawings that are extensively used in architectural presentations are perspective drawings isometric drawings and oblique drawings. Plan Section and Elevation are different types of drawings used by architects to graphically represent a building design and construction.

Break line is a thin continuous line and is drawn freehand. BROKEN-OUT SECTION VIEW A break line is used to separate the sectioned portion from the unsectioned portion of the view. Engineering Graphics with AutoCAD 2011 1e James Bethune.

Here is an object sectioned from two different directions. What is Half Section. - इजनयरग डरइग म सकशन क परकर 1.

No need for additional orthographic views. The lines are thin and are usually drawn. Section lines are thin lines.

You have learned that when making a multiview sketch hidden edges and surfaces are usually shown with hidden dash lines. The main difference between isometric and typical perspective drawings is that in the latter the lines recede to vanishing points. K half section The view Obtained When the cutting plane goes half way across the Object to the centre line.

Full section in a full section the cutting plane line passes fully through the part. Partial or Broken Out Section 4. Gaskets seals Do not show hidden detail in sectional view.

Full sections half sections broken sections rotated. Partial View Shows only the portion of the view that is contained within a boundary. 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.

Normally a view is replaced with the full section view. Half sections are commonly used to show both the internal and outside view of symmetrical objects. A full section is the most widely-used sectional view.

There is no cutting plane line. The base view is the source for subsequent views and controls the scale and alignment for them. What is Full Section.

A plan drawing is a drawing on a horizontal plane showing a view from above. A section drawing is a view taken after you slice an object then look at the surface created by the slicing. There are three major types of sections used in engineering drawing.

A short series of lectures on Engineering Drawing as Part of ENGG1960 By Paul Briozzo. A simple bracket is shown in Fig. There are a number of different types of sectional views that can be drawn.

The cross section at that point. Section line symbols are chosen according to the material of the object Section lines are generally drawn at a 45 angle. Types of Section in Engineering Drawing.

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. Types of section views 1. The cutting-plane line cuts halfway through the part and removes one quarter of the material.

A cutting plane does not necessarily need to cut the whole object. Lines Used in Section Views ¾Section Lines. Broken View Removes sections from large objects between two points and moves the remaining sections close together.

Section lines are evenly. You can create one or more base views on a drawing sheet. REVOLVED SECTION VIEW Revolved sections show cross-sectional features of a part.

Features that cannot be seen by hidden detail Cutting plane removes part section is what is left Cross hatching ois at 45 equispaced Centrelines often used for cutting planes Very thin sections not hatched eg. A second type of revolved section in Fig. In both cases the object should be standing on its base when the.

These lines are called section lining or cross-hatching. Half Section is used to the exterior and interior of the part in the same view. An elevation drawing is a view taken from a point outside the object without any slicing.

Sectional views in engineering technical drawings Half Sectional views. A half-section is a view of an object showing one-half of the view in section as in figure 19 and 20.
