Class 14 presentationlaura_geroldThe document provides guidance on dimensioning techniques for various geometric shapes and features such as prisms, cylinders, curves, holes, and angles by discussing dimension line placement, extension lines, dimensioning by size versus location, and dimensioning symbols and units to ensure drawings are clear and accurately convey design intent.
CurvesYatin SinghThis document discusses different ways to mathematically represent curves, including polynomial representations and parametric forms. It focuses on cubic polynomials and parametric representations, explaining that parametric form solves problems with explicit and implicit forms by allowing representation of curves with infinite slopes or multiple y-values for a given x-value. Parametric form also makes it easier to combine curve segments continuously. The document then discusses spline curves, which use piecewise cubic polynomial functions to fit smooth curves through points, and cubic splines specifically, providing the equations used to define cubic splines.
Datums and Datum TargetsHassan HabibThe document discusses reference frames and datums, including:
- A datum is a theoretically exact point, axis, line or plane used to define the geometric relationships between tolerance zones and the datum reference frame.
- Datum feature simulators are used to establish datums and have characteristics like perfect form and basic orientation/location.
- Common datum features include planar surfaces using 3 datum planes, inclined surfaces oriented at the basic angle, and cylindrical features using planes and axes.
- Datum modification symbols like MMB and LMB are used to define the material condition of a datum feature.
- Datum targets, indicated by symbols, are used to establish datums where full surfaces cannot be due to irregularities and include points,
Using Drawing Tools and applied geometryNUST StuffThe document discusses tools and techniques for technical drawing. It covers:
1) Preparing drawing tools like fastening paper to the drafting board.
2) Using tools like the T-square, compass, and templates to draw straight lines, arcs, circles, and at angles.
3) Applying geometric techniques to bisect lines and angles, draw parallel and perpendicular lines, and construct tangents and fillets.
Metrology and Quality Control.pptx138HemangiAhireThe document discusses measuring five features of a component using various metrology instruments.

The document concludes with a refresher on advertising techniques like exaggeration, metaphor, drama, and humor and announces the next class assignment.
Section viewsShelly WilkeThis document discusses section views and sectioning practices in technical drawings. It covers the following key points:
- The purpose of section views is to show internal details of an object, replace complex orthographic views, describe materials in an assembly, and depict the assembly of parts.
- Common sectioning practices include using different cutting plane angles for separate parts, standard hatch spacing and line thicknesses, and not drawing section or hatch lines parallel to boundaries.
- Sectional view types include full sections, half sections, offset sections, revolved sections, removed sections, and broken out sections.
- Not all features get crosshatched, even if the cutting plane passes through, such as ribs, webs
