Study Notes
CAD Modeling
- A wireframe model represents a 3D object using lines, circles, arcs, and plines along the object's edges.
- A model is a 3D object drawn to full scale and accurately positioned in relation to a coordinate system.
- A surface model has thin coatings on its outer surfaces.
- Mesh density is controlled by SURFTAB1 and SURFTAB2 variables, which determine the rows and columns of the surface mesh.
- A solid model is the most accurate representation of a real object.
- Solid modeling commands include: subtract, revolve, tabular surface, ruled surface, box, press pull, extrude, line, 3D face, region.
AutoCAD Commands
- REVSURF creates a revolved surface.
- 3D ARRAY arranges objects in a rectangular or polar array.
3D Primitives
- 3D solid primitives include wedges, boxes, spheres, tori, pyramids, and cones.
Diagram Types
- Block diagrams simplify system processes.
- Flowcharts illustrate algorithms and processes.
Logic Gates
- NOT gates invert a signal.
- AND gates require all inputs to be true for a true output.
- OR gates need at least one input to be true for a true output.
- XOR gates output true when only one input is true.
Analog Electronics Symbols
- Symbols represent various electrical components like resistors, capacitors, inductors, diodes, transistors, and operational amplifiers.
- International Standards (IEC) and ANSI provide standardized symbols.
- Different standards like JIC (Joint Industrial Council) and IEEE might have different symbology.
