- Two types of lines are acceptable for cutting plane lines in multiview drawings. It is important to use only one type of cutting plane line on a single drawing. Cutting plane lines are thick (.7mm) dashed lines, that extend past the edge of the object 1/4" or 6mm and have line segments at each end drawn at 90 degrees and terminated with arrows.

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.

The glass box method described in the chapter on Multiview Layout and Orientation dictates the proper alignment and placement of section views. The cutting plane is indicated by a straight line (this can be a “dashed” line or a “long-short-short-long” line.
Jun 28, 2022 · 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. The arrows in show the direction of view. Once again, here is an graphic example of a cutting plane line and the section that develops from it.
A cutting plane line is the line along the object where the cut would have been made. The arrows point in the direction that you are looking when drawing the section view. The surfaces of the object that are solid, when cut, are crosshatched.
