Find the Angles.
Correctly measuring your objects is only one part of drawing exactly what you see in front of you.
You also have to consider the angles of the contours of objects. Doing so can be tricky, but there are
methods that you can use to determine these angles. The method shown here is a simple one.With the same measuring tool that you used previously to
determine a scale, you can also find the angles of objects that
are not horizontal or vertical. Fix your position and extend
your arm straight out. Hold your tool in front of the curve, or
angled contour, of the object you will be drawing. You can
either remember the angle and add it to your drawing (visual-
izing it with your measuring tool can help you remember it),
or you can transfer the measuring tool to the correct position
on your drawing paper by keeping the tool in the same posi-
tion and marking the angle directly from your tool onto the
paper.
Look for the Angles
Look at the curved form, and you can see two or three angles,
representing various aspects of the curve. You can then lightly
draw these angles on your paper. Doing so will assist you in
finding the exact shape of the curve.
