11.2.6 Section Identification and Multiple Sections 9. Here are a few examples: Section lines are very light. A-6. Border lines and cutting plane lines will be the thickest lines on your drawing. If that symbol is not known, you may use the general purpose symbol, which is also the symbol for cast iron. In many cases only a small part of a view needs to be sectioned in order to show some internal detail. The construction of doors, windows, and eaves is usually shown in detail drawings. The lines in this layer should be a little wider than the object lines and the linetype should be “Phantom”. In this example, blocks A and B result after the block in figure 1 has been “Sectioned”. The different line directions indicate different parts and materials used in the assembly of this valve. Select the next point or points for the section line and press ENTER. The first form consists of evenly spaced dashes with arrowheads indicating the direction of sight. Recommended pen: 0.35 mm. CL 1 could be either the center of the box shape (a bit ambiguous itself, what surfaces establish the centerplane) or the centerplane established by the small webs on either side of the part. The cutting plane line is always shown when the cutting plane is bent or offset or when the resulting section is nonsymmetrical. First section symbol - Specifies the cutting-plane symbol for the first point of the section line. Directions: On a separate sheet of paper, complete the section view. Cutting plane lines are dashed lines, generally of the same width as the full lines, extending through the area being cut. The cutting plane may be a single continuous plane, or it may be offset if the detail can be shown to better advantage. It is more common in engineering drawings than in architectural drawings. When a cutting plane line passes entirely through an object, the resulting section is called a full section Fig. Viewing or cutting plane lines are sol 7-4 Interpreting Cutting Planes and Sections 3.

These are drawn with a long line of 10–20 mm, then a small gap, then a small line of 2 mm, then a gap, then another small line… When a cutting plane line passes entirely through an object, the resulting section is called a full section Fig. AutoCAD 2015, AutoCAD Architecture 2015, AutoCAD Civil 3D 2015, AutoCAD Electrical 2015, AutoCAD MEP 2015, AutoCAD Map 3D 2015, AutoCAD Mechanical 2015, AutoCAD P&ID 2015, AutoCAD Plant 3D 2015, AutoCAD Structural Detailing 2015, & AutoCAD Utility Design 2015, © Copyright 2020 Autodesk Inc. All rights reserved. In the LAYERS panel use the “Print Width” to the far right. The short line segments extending from the circle represent the cutting plane line. In that way, the many hidden lines on the sketch are eliminated. Make sure you understand the use of the viewing plane line to show an additional view. Please go to visibility setting, select the model category and you have to check the detail items box then click ok, so that you can see the break-line symbol in the view. ARCHITECTURAL SYMBOLS. A line width of 0.5 mm seems to work well for many drawings. SECTION LINES SYMBOLS The section lines are different for each of material’s type. The cutting-plane line is staggered through features that do not lie in a straight line. Just as an apple can be sectioned any way you choose, so can an object in a sectional view of a drawing or sketch. Half of the object is removed; the cutting-plane line generally cuts completely through along the center plane. ... T/F: The cutting plane line and arrowheads are drawn thin, like the centerline. Directions: Complete the half section view of a separate sheet of paper. Cutting plane lines are drawn 0.7 to 0.9 mm thick. cutting plane. Make sure you understand the use of the cutting plane line to show the section. A-5. The arrows at the end of the cutting plane lines are used to indicate the direction in which the sections are viewed. Top 14 International Packing Symbols You Should Know 1.
