Study Notes
Definitions in Technical Drafting
- Assembly Drawing: Illustrates how various parts of an object fit together.
- Axonometric Projection: Pictorial representation where lines of sight are perpendicular to the projection plane; includes Isometric projection.
- Cabinet Projection: Oblique projection where dimensions parallel to the third axis are reduced by half to reduce perception distortion.
- Cavalier Projection: Oblique projection with projection lines at a 45° angle to the projection plane.
- Compass: Tool used for drawing arcs and circles accurately.
- Cycloid: Curve generated by a point on a circle rolling along a straight line without slipping.
- Detailed Drawing: Focuses on a single component of a machine.
- Diametric Projection: Displays a 3D cube with one face appearing smaller relative to the other two sides.
- Dimensioning: Process of adding measurements to a drawing using either Metric or English systems.
- Divider: Instrument for transferring measurements and dividing lines or arcs into equal parts.
- Drawing: A graphic representation made of lines; can portray real objects, ideas, or design concepts.
- Drawing Pencil: Essential tool for drafters used in creating drawings.
- EDPS: Stands for Electronic Data Processing System, a computerized system for handling data.
- Ellipse: Plane curve defined by two focal points, where the sum of distances from any point on the curve to the foci is constant.
- English System: Measurement system based on feet and inches.
- Metric System: Measurement system based on meters and centimeters.
- Lettering: The art of drawing letters, distinct from simple writing.
- Mechanical Drafting: A method for creating precise drawings using specialized tools.
- Multi-View Projection: Technique for representing a 3D object using a series of standardized 2D views.
- Oblique Projection: Creates 2D images of 3D objects through a simplified drafting method.
- One-Point Perspective: Drawing technique with a single vanishing point; all parallel lines converge at this point.
- Orthographic Drawing: Object depicted in multiple views through perpendicular projection on drawing planes.
- Perspective Drawing: Technique to render solid objects in 2D, reflecting depth and spatial relationships.
- Pictorial View: Shows an object revealing its three visible faces.
- Protractor: Tool for measuring angles in degrees for arcs and circles.
- Sketch: Quick, freehand drawing not meant as a final product.
- Three-Point Perspective: Employs three sets of orthogonal lines and vanishing points to depict objects.
- Trimetric Projection: Axonometric projection showing an object with unequal tilt of all three primary axes.
- Two-Point Perspective: Linear perspective employing two vanishing points along a horizon line.
- Linear Perspective: Technique using lines to create a realistic impression of space on a 2D surface.
