Across
- 1. a heavy dashed line type that represents an edge that is not directly visible
- 5. a drawing that contains views of an object projected onto two or more orthographic planes
- 6. A pictorial representation (such as a picture, map, or technical drawing) used to convey detailed information. In engineering, graphical models are created using standards of engineering graphics to document a design and are often referred to as technical drawings.
- 8. an object that provides information about a feature, such as the length of a wall, the diameter of a fastener, or a detail callout. Annotation objects can include dimensions, notes, or other types of explanatory symbols
- 10. A line that defines the center of arcs, circles, or symmetrical parts. A center line is half as thick as an object line.
- 11. A working model used to test a design concept by making observations and necessary adjustments.
- 12. lightly drawn line used to guide drawing other lines and shapes
- 13. the mental representation and manipulation of two- and three-dimensional objects
- 15. a solid modeling design method in which an object is created by adding volume to a smaller object
- 19. the process or result of taking away or removing characteristics from something to reduce it to a set of essential characteristics
- 20. a heavy solid line used to represent the outline of an object. An object line always takes priority over other line types
- 22. a method of representing three-dimensional objects on a plane having only length and breadth. It is also referred to as right-angle projection or orthographic view
- 23. A visual representation of an idea. A conceptual model can be a sketch, concept map, schematic, flow chart, or any other visual representation
Down
- 2. a strategy in which geometry is defined in such a way that changes produce desired, predictable results
- 3. a process that uses a computer to assist in designing something, such as a part, electrical circuit, or building
- 4. A representation of a real-world situation or system using mathematical concepts and language.
- 7. a solid modeling design method in which an object is created by subtracting volume from a larger object
- 9. 3D modeling in which geometry is created in association with other geometry
- 14. intersecting or lying at right angles; perpendicular
- 16. a form of pictorial representation or graphical model in which all dimensions parallel to the three principal spatial axes are shown in their true proportions
- 17. a mark on a drawing that shows the location of a hole, cylinder, or other round feature as a pair of perpendicular lines that cross at the center of a feature
- 18. the relationship between a distance or area on a map and the corresponding distance or area on the ground, commonly expressed as a fraction or ratio
- 21. adds depth to open or closed sketch profiles or faces
