Sep 4 – Sep 22 2.5 weeks
Unit Summary As a part of the Engineering Design Process, students will learn the art of technical sketching and different sketching techniques -- types of sketches, line conventions, shading, drawing conventions, etc.
This and all following units are set up to deliver as virtual with on-campus optional
Big Ideas
Technical drawings convey information according to an established set of drawing practices which allow for detailed and universal interpretation of the drawing.
Hand sketching of multiple representations to fully and accurately detail simple objects or parts of objects is a technique used to convey visual and technical information about an object.
Two- and three-dimensional objects share visual relationships which allow interpretation of one perspective from the other.
The style of the engineering graphics and the type of drawing views used to detail an object vary depending upon the intended use of the graphic.
Build projects following the Design Process (and using sketching techniques where appropriate)
Essential Questions
What Design Process step uses Concept versus detailed technical sketching?
What is the difference between an isometric, oblique, perspective, orthographic, and multi-view drawings and when are these drawings used.
What can cause a technical drawing to be misinterpreted or to be inadequate when conveying the intent of a design to someone unfamiliar with the original problem or solution?
In what ways can technical drawings help or hinder the communication of problem solution in a global community?
Strong spatial-visualization skills have been linked to success in engineering. Why are spatial-visualization skills so important to engineering success?
Priority TEKS
Identify line types (including construction lines, object lines, hidden lines, and center lines) used on a technical drawing per ANSI Line Conventions and Lettering Y14.2M-2008 and explain the purpose of each line.
Identify general rules for dimensioning on technical drawings used in standard engineering practice.
Hand sketch isometric views of a simple object or part at a given scale using the actual object, a detailed verbal description of the object, pictorial view of the object, or set of orthographic projections. -13.3.3
Apply appropriate and sufficient annotation methods, including dimensioning, to a drawing to fully describe an object or system using accepted technical drawing techniques. -13.6.2
