Section Views. Section views are used extensively to show features of an object or an assembly that are not easily visible from the exterior. This method can be used with both simple and complex objects and involves the use of a cutting plane that dictates what portion of the object you want to remove to reveal a more complex interior.

A sectional view represents the part of an object remaining after a portion is assumed to have been cut and removed.The exposed cut surface is then indicated by section lines.Hidden features behind the cutting plane are omitted, unless required for dimensioning or for definition of the part.Section lines, or hatching, that represent the cut surface usually consist of thin parallel lines, as shown below, drawn at an angle of approximately 45° to the principal edges or axes of the part. For most purposes, the general use symbol of cast iron is used. When it is desired to indicate differences in materials, for example on assembly drawing...
Cutting plane lines which show where the cutting plane passes through the object, represent the edge viewof the cutting plane and are drawn in the view(s) adjacent to the section view. Here the cutting plane is drawn as an edge in the top view, which is adjacent to the sectioned front view. This is a frontal cutting plane. Lines of sight should alw...
Whenever practicable, and except for revolved sections, you should project sectional views perpendicular to the cutting plane and place it in the normal position for third angle projection.You should never show the views in first angle projected position on a third angle projection drawing.When the preferred placement is not practical you may remove the sectional view to some other convenient position on the drawing, but it must be clearly identified, usually by two capital letters,...Normally, you should not change orientation of the view, but if this becomes necessary, you must state the number of degrees through which it is revolved.- Cutting Plane. A surface cut by the saw in the drawing above is a cutting plane. Actually, it is an imaginary cutting plane taken through the object, since the object is imagined as being cut through at a desired location.
- Cutting Plane Line. A cutting plane is represented on a drawing by a cutting plane line. This is a heavy long-short-short-long kind of line terminated with arrows.
- Section Lining. The lines in the figure above, which look like saw marks, are called section lining. They are found on most sectional views, and indicate the surface which has been exposed by the cutting plane.
- Full Sections. When a cutting plane line passes entirely through an object, the resulting section is called a full section Fig. 7 illustrates a full section.
Apr 10, 2024 · Apr 10, 2024. In the realm of engineering design, CAD drawing section views play a crucial role in conveying the intricate details of a design. This article explores the fundamentals of...
A Section or cross section is a view generated from a part or assembly on a cutting plane or multiple cutting planes that reveals the outlines on the inside or assembly fits. Sections normally comprise of two parts, firstly the Section Cut indicator with identification.
Jul 1, 2020 · 6 Types of sectional views. Full sections. This is the most common section (called a full section) with the imaginary laser cutting a line across the entire construction, offering a view of a portion of the building with the rest of it put to one side. Half sections or views.
What is a section view? A sectional view or a section looks inside an object. Sections are used to clarify the interior construction of a part that can not be clearly described by hidden lines in exterior views. By taking an imaginary cut through the object and removing a portion, the inside features may be seen more clearly.
