One end of the leader terminates either in an arrowhead or a dot.

. Dimensioning Arcs Circles and Diameters. Where a leader line is used to point towards the feature being dimensioned. 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.
Leader Hatching type lines must be drawn thin and continuous. 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. They are uniformly spaced about 1 mm to 2 mm apart.
A drawing leader consists of an arrow and a text. 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. Engineering Working Drawings Basics Page 1 of 22 Engineering Working Drawings Basics Engineering graphics is an effective way of communicating technical ideas and it is an essential tool in engineering design where most of the design process is.
From any suitable portion of the reference note or number a short line is drawn parallel to the lettering. For general engineering drawings the types of lines recommended by the Bureau of Indian Standards shown in table 2 must be used. The leader line should terminate in an arrowhead or dot.
Spot the beginning and end points. In technical drawings the standards of the leaders and arrows are very important. Consider thin lines are 03 mm and thick lines 06 mm in technical drawing.
These lines are drawn to make the section evident. This line is used to show hidden edges of the main object. B Dimension lines show the direction and extent of dimension.
Avoid dimensioning to hidden lines wherever possible. Leader or Pointer Lines. This can be a dot if the line ends within the outline of the part an arrow if the line touches the outline or centre line.
A leader line consists of two parts. The parts list will also contain information regarding the quantity required of each component for the assembly its individual single- part drawing number and possibly its material. Minimize or avoid leader lines crossing dimension or extension lines.
Leader line is drawn may be 30 or 60 to the bottom of dimensions. Leader line in engineering drawing Nail artwork conjures up Every person. Draw the line firmly with a free and easy wrist-and-arm motion.
Figure 34 Engineering drawing line types A to K ISO 1281982 Figure 34 Engineering drawing line types A to K ISO 1281982 leader lines cross hatching outlines of revolved sections short centre lines thread routes and symmetry equals signs. Leader Line Leaders are more thin lines used to point to an area of a drawing requiring a note for explanation. Leader line Dash thick line Hidden.
These are drawn may be vertical or inclined to indicate the height of the dimension figure. Leaders are used to connect numbers references or notes to the appropriate surfaces or lines on the drawing. Should you be a colorful Lady Then you can certainly take up brighter color tones for the nails if you want delicate factors so certainly your temper will get on nail paints that happen to be a bit boring and less flashy.
Hold the pencil naturally. This line is used to represent the location of a cutting plane. End of the extension line.
Minimize extension lines crossing themselves or visible lines. A type B line thin continuous straight going from the instruction to the feature. C Leader lines are used to direct an expression in note form to the intended place on the drawing.
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. Leader line is drawn may be 30 or 60 to the bottom of dimensions. Avoid chain dimensioning especially for mechanical objects.
This line is used to represent the center line for circles and arcs. Dimension Marking with Center Lines in Engineering Drawings. They are generally used as thin lines.
Uniform leaders can be easily achieved in modern CAD software using annotative. But 30 o to 60 o is preferred. A Extension lines are used to indicate the extension of an edge or point to a location outside the part outline.
Numbers in balloons with leader lines indicate the position of the component on the drawing see Fig. You can see the general standards that are used generally below. The ISO type C lines are thin wavy and continuous as shown in Figure 37.
Leader lines should be inclined between 15 o to 75 o. Looking at the drawing. Sometimes leaders are used in place of extension and dimension lines especially when dimensioning arcs and circles.
Technical Drawing Line Types. A leader line is a line referring to some form of feature that could be a dimension an object or an outline. From this line the remainder of the leader is drawn at an angle dog leg to an arrowhead or dot.
Swing the pencil back and forth between the points barely touching the paper until the direction is clearly established. A leader may also be used to indicate a note or comment about a specific area. These are thin continuous lines drawn from a dimension figure to the feature to which it refers.
A leader line is a thin line on a design or blueprint that is used to connect a dimension line with a particular area or point on the drawing. Leaders should have a uniform and consistent appearance at all drawings independently of the drawing scale. For general engineering drawings the types of lines recommended by the Bureau of Indian Standards shown in table 2 must be used.
