Blueprint Reading (Level I)
Audience:
Skilled trades, fabricators, and others needing an understanding of symbols and operations when viewing drawings.
Duration: 16 hours
Prerequisites: Good understanding of shop mathematics in fractions, decimals and percentages.
Description:
Introduction to print reading for individuals who must develop skills in reading & accurately interpreting industrial drawings and in preparing simple technical sketches. Instruction in blueprint reading is integrated with manufacturing or construction drawing courses to enhance preparation of orthographic and other drawing techniques.
Topics Include:
- Basic blueprint reading
- Lines and object lines
- Hidden and center lines
- Extension and dimension lines
- Projection lines
- Three view drawings
- View arrangements
- One & two-view drawings
- Auxiliary views
- Dimensioning cylinders, circles and arcs
- Sizing for holds and angles
- Location dimension for points, centers and holes
- Tolerances for fractional and angular dimensions
- Dimensioning tapes and machined surfaces
- Detail drawing and assembly drawing
Objectives: Upon completion of this course, participants will be able to:
1. Locate dimensions for points, center, and holes.
2. Compute tolerance for fractional and angular dimensions.
3. Draw internal and left-hand threads.
4. Interpret various drawings for dimensions, symbology, and understanding.
5. Draw and sketch three view drawings: Dimension, construct fixture, and part drawing.

Layout for Metal Fabrication (Level I)
Audience: Participants requiring fundamental knowledge of layout techniques applied to metal fabrication.
Duration: 32 hours
Prerequisites: Participants must have a good working knowledge of basic shop mathematics, including algebra and trigonometry at the high school level.
Description:
Development of geometrical elements of structures and their intersections by radical & triangulation methods used in metal forming layout. The actual layout of patterns on steel and the fabrication of small jigs & fixtures as individual class projects.
Topics Include:
- Pattern Drafting: parallel, radial, and triangulation.
- Equipment: scale, triangle, protractors, compass, and dividers
- Fundamental Terms: lines, angles, surfaces, solids, geometric construction, polygons, and circles
- Simple Patterns: steps of layout, notching and clipping, and pattern development
- Parallel Line Development: rectangular shapes and round shapes
- Radial Line Development: right angle, tapers, square base, triangulation, plane surfaces, true length, rectangular transition, and bend allowance
- Specification: class projects
Objectives: Upon completion of this course, participants will be able to:
1. Use acceptable industrial practices to calculate and evaluate layout strategies.
2. Use proper hand tools and equipment to physically layout various metals before the start of fabrication.
3. Fabricate including bend, shape, and drill and prepare for welding sample class projects in accordance with proper shop techniques.
