The cutting plane method is commonly used for solving ILP and MILP problems to find integer solutions, by solving the linear relaxation of the given integer programming model, which is a noninteger LP model.
What is the two types of cutting plane line?
Answer: There are two forms of cutting plane lines approved for engineering drawings. The first form consists of evenly spaced dashes with arrowheads indicating the direction of sight. The second form consists of alternating long dashes and pairs of short dashes.
Where do cutting plane lines go?
Cutting plane lines are thick lines that run through the center of the object that the interior wants to provide an interior view of. Two perpendicular lines with arrows showing in which direction the interior of the object should be viewed are drawn at the end of the line.
How does the cutting plane line differ from the viewing plane line?
VIEWING PLANE LINES are used to indicate the plane or planes from which a surface or several surfaces are viewed. CUTTING PLANE LINES are used to indicate a plane or planes in which a sectional view is taken.
What does a cutting plane line look like?
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.
What is a phantom line?
Lines that are made visible as dots or dashes to reveal the edges of objects currently hidden from view.
What purpose do the arrowheads on a cutting plane line serve?
Dimension line arrowheads touch extension lines. Leaders are more thin lines used to point to an area of a drawing requiring a note for explanation. They are preferably drawn at a 45° angles. A cutting plane line (very heavy) helps to show the internal shape at a part or assembly by slicing through the object.
Why are webs and spokes not sectioned?
Ribs, webs, spokes, gear teeth and other thin features are not section lined when the cutting plane passes parallel to the feature. Adding section lines to these features would give the false impression that the part is thicker than it really is.
What is the relation of cutting plane line and section line?
Cutting Plane Line: Used to show where the object is being cut. ( Phantom line type) Section Lines: Used to indicate where the cutting plane cuts the material. Section lines are thin and the symbols (type of lines) are chosen according to the material of the object. Section lines are generally drawn at a 45° angle.
Is a plan where the cutting plane line is drawn?
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. The cut line is called a “cutting plane”, and can be done in several ways.
What are the 7 types of section views?
There are a number of different types of sectional views that can be drawn. A few of the more common ones are: full sections, half sections, broken sections, rotated or revolved sections, removed sections, offset sections, and assembly sections.
What is the difference between the section line and the centerline?
Centre lines are drawn to indicate the exact centre of a component being drawn. They are made from a series of lighter long and short dashes. Section lines are special lines placed on a drawing which indicate the area of the drawing through which an imaginary cut has been made to reveal internal details.
