FORMAL PLASTER CAST PROJECT
DOMINANT, SUBDOMINANT, AND SUBORDINATE
To understand what entails good craftsmanship.
To establish relationships between volumes.
To become aware of proportions, mass and balance and contrasting shapes.
To understand the notion of activating space and deal with the basics of engineering (balance and weight).
To create a unified form combining three rectilinear shapes (a dominant, a sub-dominant, and a subordinate), through piercing, wedging, and/or cradling.

Below are 3 sculptures that pierce, wedge, and cradle. Can you guess what image represents what concept?
note that many items can be found in Home Depot Painting Section, look for

Below are plaster carving tools (Do not purchase the plaster carving tools). When working at home, try finding tools around the kitchen or tool shed that could substitute these tools, such as steak knives, box cutters, hack saws, screw drivers, etc.
Make 10 or more rectilinear volumes in chipboard or bristol board. The volumes should vary in length,
width, and height. Measure and cut with precision for an accurate form. Organize the rectangles in groups
of three, keeping these principles in mind:
Start by designing the dominant,
then the sub-dominant. Spend a little time on this relationship. Quickly complete
element, and quickly arrange in a three-dimensional grouping. This will give you a sense of the overall
configuration. Then you can begin to refine.
The volumes you use choose should vary in character as much as possible, and no two should have the
same measurements. You should be able to assess the differences in volume of the three elements by eye.
If you have to measure, they are too similar in size.
The dominant volume is the largest element, the most interesting and dramatic in character. It occupies the
dominant position in the group. The sub-dominant complements the dominant in character. The
relationship between the two should be visually interesting by the contrast in character, and the position of
each, usually when the axes are not parallel.
The subordinate makes the design still more interesting by introducing a third visual element and axis. The
third element should make the design more three-dimensional, complement the existing forms, and
complete the unity of the design. It is not as independent as the dominant/sub-dominant. It should be
contrasting but sensitive to the other forms. It must be designed to fill what is missing in the other two.
Always conceive a design from all positions.
-Emphasize either the vertical or horizontal proportion in each sketch.
-All joints should appear structural.
-A balance of directional forces should be established.
-The design should look interesting and three-dimensional from every position.
-It should achieve a an effect of unity in which every part relates to every other part, and every design
relationship contributes the whole.
Bring in materials to class. Begin
making rectilinear forms in class using bristol board and blue tape, white
tape, or masking tape.
Arrange forms, making adjustments as needed (cut into forms to pierce, wedge and cradle). Decide on three final configurations to be viewed next class.
Take note: You are now using paper as a material for model making; whereas, in the previous project you used paper as a sculptural material.
Enlarge your form twice the size (make a small one and a large one). Use the small one to familiarize yourself with sanding, gluing, patching, and engineering.
