You can see the general standards that are used generally below.
. A leader line is a line referring to some form of feature that could be a dimension an object or an outline. An extension line extends a line on the object to the dimension line. Extension lines begin 15 mm from the object and extend 3 mm from the last dimension line.
These lines are drawn to make the section evident. A Extension lines are used to indicate the extension of an edge or point to a location outside the part outline. They are preferably drawn at a 45 angles.
One end of the leader terminates either in an arrowhead or a dot. This line is used to show hidden edges of the main object. Join 7tothe point B.
The thickness of the lines must be chosen according to the type and size of the drawing from any of the six groups given in Table 1. Leader linea thin solid line used to indicate the feature with which a dimension note or symbol is associated- Leader lines are generally a straight line drawn at an angle that is neither horizontal nor vertical Leader lines are. B Dimension lines show the direction and extent of dimension.

A leader line consists of two parts. 4 5 and 6. 170 mm 235 mm Binding.
A leader is a thin line used to connect a dimension with a particular area figure 24. Continuous thin line find its application in engineering drawing as Dimension line Projection line Leader line. This line is used to represent the location of a cutting plane.
For general engineering drawings the types of lines recommended by the Bureau of Indian Standards shown in table 2 must be used. Uniform leaders can be easily achieved in modern CAD software using annotative. Leader lines should be inclined between 15 o to 75 o.
They are generally used as thin lines. Following are the different types of lines used in engineering drawing. A leader line is a continuous straight line that extends at an angle from a note a dimension or other reference to a feature An arrowhead touches the feature at that end of the leader At the note end a horizontal bar 6 mm long terminates the leader approximately 3 mm away from mid-height of.
They are uniformly spaced about 1 mm to 2 mm apart. A type Continuos Thick. The first dimension line should be approximately 12 mm 06 in from the object.
A drawing leader consists of an arrow and a text. Minimize or avoid leader lines crossing dimension or extension lines. Paperback with Four color Jacket Cover Pages.
Spot the beginning and end points. Leader line is drawn may be 30 or 60 to the bottom of dimensions. What are the types of line in drawing.
ENGINEERING DRAWING PLANE AND SOLID GE O M ETRY By N. End of the extension line. 7 Thin chain line find its application as.
B type Continuous THIN. Plus and minus dimensioning is the allowable positive and negative variance from the dimension specified. Avoid chain dimensioning especially for mechanical objects.
Leader or Pointer Lines. A type B line thin continuous straight going from the instruction to the feature. Set the divider to a convenient length and mark off seven spaces on AC.
But 30 o to 60 o is preferred. Consider thin lines are 03 mm and thick lines 06 mm in technical drawing. Visible lines are drawn as solid thick lines.
This line is used to represent the center line for circles and arcs. Dimensioning Arcs Circles and Diameters. A leader line consists of two parts.

More specifically the arrow size arrow inclination the text size allow line weight etc should all be the same for all leaders in a drawing. Continuous thin line find its application in engineering drawing as Dimension line Projection line Leader line. Leader lines and Termination of the dimension line.
Leader line is the thin solid line used to indicate the feature with which a dimension note or symbol is associated. Vi Leader Lines A leader or a pointer is a thin continuous line connecting a note or a dimension figure with the feature to which it applies. Related Questions on Engineering Drawing.
Leader Hatching type lines must be drawn thin and continuous. Leaders are more thin lines used to point to an area of a drawing requiring a note for explanation. These are drawn may be vertical or inclined to indicate the height of the dimension figure.
Tolerance is the amount a particular dimension is allowed to vary. In drawings that do not have cutting planes visible lines will be the thickest lines drawn. This line is located in front of cutting planes outlines of adjacent parts censorial Lines and to state center of gravity.
C Leader lines are used to direct an expression in note form to the intended place on the drawing. In technical drawings the standards of the leaders and arrows are very important. Minimize extension lines crossing themselves or visible lines.
