Calibration

This exercise introduces the process of calibration as a means of transferring between three-dimensional spatial constructs and two-dimensional representations. The calibration occurs between a physical model and an ordering system. The ordering systems will be a simple grid. This method brings consistency and precision to the work process.

Through this exercise you will:

• Calibrate a model using an ordering system.
• Clarify the relationship of planar elements using the ordering system.
• Construct orthographic drawings of a physical model.
• Advance an understanding of graphic conventions

Definition:

Calibrate: to adjust or mark (something, such as a measuring device) so that it can be used in an accurate and exact way. "Calibrate." (Merriam-Webster.com. Merriam-Webster, n.d. Web. 5 Feb. 2016.)

Principles:

• In the early phases of design, it is important to remain flexible. Working methods and media should support a fluid forming or ideas. Later, when the arrangement is closer to resolution, an organizational system can be applied as a means to clarify relationships. Imposing the organizational system is a means of calibration.
• The simplest organizational system is a grid with equal spacing in two directions. It is very effective when working with planes that are perpendicular and parallel to one another.
• In architecture common types of orthographic drawings include plans, elevations, and sections.
• In orthographic drawings objects are flattened. The eye can never see objects as shown in orthographic drawing. Instead this type of drawing allows us to study composition and arrangement and provides us with information in which to construct the subject in three dimensions.
• Construction drawings vs. presentation drawings. Orthographic drawings that are intended for presentation are different than orthographic drawings intended for construction. Construction drawings focus on the methods and materials for building; the information inside the floors, walls and other masses takes priority. Presentation drawings focus on communicating the nature of the space, the area outside the floors, walls and other masses. In presentation drawings, typically, the information within the cut mass (the floors, walls and other masses) is not described. In presentation drawings we are interested in the spatial profile, not the assembly inside the walls and floors. In this class we are interested in developing presentation drawings.

Assignment Overview: In this exercise you will be calibrating your physical model using grids and datums. The grids will be used to calibrate planes in plan view. The datums will be used to establish heights of masses and planar elements. The following constraints must be met:

• Vertical planes must have a thickness of 6”.
• Horizontal planes must have a thickness of 12”.
• The spatial profile line should be shown as a heavy line. Lighter lines should be used for un-cut elements. A hidden line must be used to illustrate overhead planes in your plan.
• Planes should have the following relationships to the grid in plan view and horizontal datums in sections. Your grid spacing will be 1'-0". Please note that a larger grid spacing is shown for the illustrations.

Assignment: 

Calibrate your plan to the grid. Your plan cut should be chosen in a place that provides the most information. Discuss your choice before proceeding. This is a draft so construction lines can be left, but the drawing must be precise. The grid must appear on the drawing. It is recommended that you use a 4H lead for the grid. Lineweights must illustrate the distinction between cuts and non-cuts.  

Cut two sections through your project. Again the sections should be selected that provide the most information. Discuss your choice before proceeding. 

The choice of paper is yours. Once reviewed, scan and upload the drawing.

Assessment: The basis for your grade will be craftsmanship, the meeting of the constraints, and the completion of the product and procedures described above.
