standard Students will create technical freehand sketches

Freehand sketches Often understood to mean a crude or sloppy drawing Should be made with careful attention to: Detail Proportion Clarity Correct line widths

Purpose of sketching Engineers and Architects give sketches to drafters in order for them to create working drawings Sketching: Sorts out ideas Shows others ideas Good preparation for more complicated drawings Effective and economical

Tips for sketching Use your pencil lightly at first, then darker once you are sure of a line’s placement Not always drawn to scale Use your space – fill up the paper you are given. Smaller sketches are not better sketches Correct proportions are imperative (check regularly) Height, Width, Length Measure with your pencil

Steps to create a straight line Locate both endpoints first Keep your eye on the point where the line will end Draw light lines between points Darken the lines to create to create a continuous line Your eye leads the pencil along the light sketch line

Steps to create a sketch Select your view Block in lightly the shape of the object Block in details in each view Erase unwanted construction lines Darken lines

Shading your sketch Line shading Stippling Smudge Method uses lines to shade Lines are closer together to make darker Lines should be parallel To shade curved objects use straight or curved lines Stippling Use tiny dots The closer the dots the darker the area Smudge

Contrast When shading, contrast is very important Contrast – the state of being strikingly different from something else This means the darkest part of your sketch should be VERY dark, and the lightest part should be left white.
