Section Plane Engineering Drawing

A section lined area is always completely bounded by a visible outline never by a hidden line.
Section plane engineering 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. 7 illustrates a full section. Engineering curves 1 engineering curves used in designing certain objects conic sections sections of a right circular cone obtained by cutting the cone in different ways depending on the position of the cutting plane relative to the axis of cone three conic sections can be obtained ellipse parabola and.
The cut line is called a cutting plane and can be done in several ways. Hidden lines should be omitted in section views unless they are necessary as in fig. Section plane at a distance of 12 mm above the ground.
When a cutting plane line passes entirely through an object the resulting section is called a full section fig. 2a shows the imaginary cutting plane in perspective view. This is a mechanical part drawing with a 2d and 3d section view through the center.
Draw its front view side view and sectional top view. These lines are called section lining or cross hatching. Visible edges and contours behind the cutting plane should be shown as below in fig.
The following slides will help show the several methods or types of section views visualizing the cutting plane. The section views show what s inside if the part was sliced in two. Project the section to the top view.
The diagonal lines on the section drawing are used to indicate the area that has been theoretically cut. Sections and sectional views are used to show hidden detail more clearly. Keep the following things in mind when drawing sectional views.
