Step 9: Measure from the top of the head to the ramus and mark a horizontal line across the ramus.
Step 10: Sight the angle from the occipital plane to the measured point of the ramus and build clay along this angle.
Step 11: Sight and mark the angle from the top of the sternal notch to the 7th cervical vertebra.
Step 12: Measure the distance from the top of the sternal notch to the 7th cervical vertebra and build clay up to this distance.
Step 13: Drop an angle in clay from the angle at the point of the ramus down to the 7th cervical vertebra.
To build the width of the head:
Step 14: On the model, measure across the widest point of the head, about an inch about the ears.
Step 15: Mark the halfway point along the angle from the frontal plane to the occipital plane. This is about the point where the ear attaches to the head. Build the widest point of the head about an inch above this mark until it matches the measurement previously taken.
Step 16: Measure the model’s frontal plane from temporal to temporal and build clay out to this measurement.
Step 17: Sight the angle where the ear attaches to the head and mark it at the halfway point from Step 15. Bring this angle down. This is the jaw line.
Step 18: Measure the height of the head from the top to the chin. Draw a horizontal line at the base of the chin to intersect with the jaw line. Fill in clay from the widest point of the head along this line to the frontal plane.
Step 19: Fill in clay from the brow to the chin line so it creates a vertical plane.
Step 20: Measure the width of the ramus and at the jaw line this will be the widest point. Fill out clay to this measurement.
Step 21: Mark the halfway point from brow line to chin. This is where the bottom of the nose is located. Draw a horizontal line to the back of the head. This is the base of the skull at the back of the head. Fill out clay to this point.
