Constructing the Basic Trouser Block
Added Aug 9, 2009
Measure the waist-to-hip distance downward from the origin point O (point B) and draw in a third horizontal line of the same width as the other two - this is the hip line.
There is an important issue here. The waist-to-hip measurement is a difficult one to make precisely, whereas the crutch depth (body rise) is much more precise, even when estimated using the formula given in the previous step. Sometimes when one comes to construct the curve from the crutch depth line to the hip line, the distance may seem very small. If this is the case, DO NOT TAMPER with the crutch depth line. Instead, slide the hip line upwards a small distance. The location of the hip line being fairly uncertain, this will give an appropriate curve. If you lower the crutch depth line, you will create a VERY deep crotch. Unless you want this, stay clear of such a change.
