Akash and His Members Present Infront of you The presentation on Sketching

Sketching And Shape Description Group# Innovative Mechanicts

What is Sketching ?? 1. > The first hand drawing in engineering Drawing is called Sketching.. 2. * It is technique of making drawing without using instruments other than pencil eraser or Sharpener including paper for sketching 3. * It is first step for the representation of an scale drawing (Instrumental drawing)..

Sketching 4: * It means a technical person or an engineer represents his ideas initially in the form of sketches with correct proportion but not to SCALE..

Purpose of Sketching 1. To transmit the information quickly to the other. 2.To transmit the ideas of designers to draftsmen 3.In field of factory it occurs when repairs/changes are made in an existing drawing 4.To make the studies of layout views there required a mechanical drawing 5.It is a communication/ discussion between Engineer and workmen 6.For teaching aid during the discussion on different problems, the sketching is used etc...

Sketching instruments and Materials 1: pencil * (a): H-grade pencil is good all around soft (b): HB pencil may be used for sketching (c): The pencil should have conical point and frequently sharped

Sketching instruments and Materials 2: Sandpaper/Sha rpener > The Sandpaper or Sharpener is used to make the conical point of pencil

Sketching instruments and Materials 3: paper > Experienced draftsman may use plane, unrolled paper for sketching while it is better to Sketch on the cross sectioned (graph paper). >Using graph paper for sketching it is easier than the plane paper for drawing straight lines > In sketching the graph paper scores good properties than the plane paper

Sketching instruments and Materials 4: Eraser >It is used in sketching for * Correction * Editing purpose * And erasing unnecessary lines etc....

Sketching Horizontal lines 1:. Locate the two points which should be parallel to top /bottom and mark them

Sketching Horizontal lines 2: Sketch short light line from left to right and backward between two points by pulling from points 1 to 2

Sketching Horizontal lines 3: now dark the line using one continuous, keep your eyes on the ending point

Sketching vertical line 1: similar to Horizontal lines, locatetwo points from top to bottom, parallel to vertical boundary lines

Sketching vertical line 2: same as horizontal line draw a light line from top to bottom in given points

Sketching vertical line 3:Now meet the two given points 1 & 2 from top to bottom

Sketching inclined lines 1:Similarly but from low left to upper right

Sketching inclined lines 2: Or upper left to lower right

An Sketch Here you can see the sketched two circles,used different lines
