- 5. A solid modeling technique where geometry is added to existing model geometry
- 8. also called a "UI," is the means in which a person controls a software application or hardware device. Nearly all software programs have a graphical user interface, or "GUI," that includes graphical controls which a user can select using a mouse or a keyboard.
- 10. 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.
- 14. A visual representation of an idea. A conceptual model can be a sketch, concept map, schematic, flow chart, or any other visual representation.
- 16. The process of taking away or removing characteristics from something in order to reduce it to a set of essential characteristics.
- 18. A method of representing three-dimensional objects on a plane having only length and breadth. Also referred to as right angle projection or orthographic view.
- 20. 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.
- 23. shows the location of a hole, cylinder, or other round features on a drawing as a pair of perpendicular lines that cross at the center of a feature.
- 24. The process of creating a solid model or three-dimensional object using a modeling and design application on a computer.
Down
- 1. The mental representation and manipulation of two- and three-dimensional objects.
- 2. Lightly drawn line to guide drawing other lines and shapes.
- 3. (CAD)A process that uses a computer to assist in designing something, such as a part, circuit, or building.
- 4. A heavy dashed line that represents an edge that is not directly visible.
- 6. 3D modeling where geometry is created with association to other geometry.
- 7. A strategy in which geometry is defined in such a way that changes produce desired, predictable results.
- 9. A heavy solid line used on a drawing to represent the outline.
- 11. 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.
- 12. 1. Something established by authority, custom, or general consent as a model or example. 2. Something set up and established by authority as a rule for the measure of quantity, weight, extent, value, or quality.
- 13. A line that defines the center of arcs, circles, or symmetrical parts. A center line is half as thick as an object line.
- 15. A solid modeling technique where geometry is subtracted from existing model geometry.
- 17. A working model used to test a design concept by making observations and necessary adjustments.
- 19. Intersecting or lying at right angles; perpendicular.
- 21. The ratio or 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.
- 22. A representation of a real-world situation or system using mathematical concepts and language.
- 25. A drawing which contains views of an object projected onto two or more orthographic planes.
