Sheeraz Ali  \nList of Instruments  \n1. Drawing Board  \n2. T-Square  \n3. Set-Square  \n4. Drawing Templates  \n5. Compass for Engineering Drawing  \n6. Lead Pencils  \n7. Eraser  \n8. Sharpener  \n9. Sand Paper  \n10.Adhesive Tape  \n11. Pointer (0.1 mm)  \nGeneral Instructions for all drawing sheets  \n1) Bring all the mentioned equipment in each lab session.  \n2) Clean the drawing board by using the duster.  \n3) Place the drawing sheet correctly straight on the drawing board by the help ofT-square.  \n4) Paste the drawing sheet on the drawing board by suing adhesive tape or drawing pins, make sure the adhesive tape or pins are only 10 mm away from each corner and side of drawing sheet.  \n5) Before any drawing make sure the drawing pencil is sharp and during drawing any line keep the pencil rotating so that the thickness of line remain same.  \n6) Draw the boarders on the drawing sheet 20 mm from the left side and 10 mm from top, bottom and right sides.  \n7) Draw the title block on the right bottom corner of sheet, having length 180 mm and height 65 mm, and divide the title block into 6 horizontal rows, each having 10 mm spacing.  \n8) Measure the total length and width of the drawing sheet and the object which is required to be drawn, within the boarders drawn.  \n9) Calculate the horizontal margins for all orthographic drawings by subtracting the total length + Width of the object from the total length of the sheet and dividing it by 3, similarly in case of vertical margins the height + Width of object will be subtracted from the height of sheet and divided by 3.  \n10)For erasing any unnecessary or mistakenly drawn lines use erasing shield.  \n11)Use duster for removing any rubber residues, left on the sheet rather using your hands.  \n12)Use drawing template for drawing any circle having radius smaller than 5 mm.  \n13)After completing the drawing carefully remove the tape or pins and store it safely in file.  \nList of Drawing Sheets  \n1.
