3D Computer Modeling Review Crossword

3. A straight line or plane that touches a curve or curved surface at one point.
8. The surface that 2D profiles can be sketched on.
9. A rounded interior blend between two surfaces. Some uses are to strengthen joining surfaces or to allow a part to be removed from a mold.
10. A full-scale working model used to test a design concept by making actual observations and necessary adjustments.
15. At an angle of 90 ̊ to a given line, plane, or surface.
16. A sequential record of the construction steps in a 3D modeling program
17. A conical-shaped recess around a hole that is often used to receive a tapered screw.
19. Used to describe the size and location of individual geometric shapes.
24. Turning around an axis or center point.
25. A cylindrical recess around a hole, usually to receive a bolt head or nut.
27. To add explanatory notes to.
28. Construct or manufacture an industrial product.
29. Cut off irregular or unwanted parts.
30. A closed geometric figure in a plane formed by connecting line segements endpoint to endpoint with each segment intersecting exactly two others. Polygons are classified by the number of sides they have, such as a triangle has three sides, a quadrilateral has four sides, and a pentagon has five sides.
31. The use of a computer to assist in the process of designing a part, circuit, building, etc.

1. Designed to be practical and useful.
2. A triangle that has a 90 degree angle.
4. Parallel to the Y axis.
5. An iterative decision-making process that produces plans by which resources are converted into products or systems that meet human needs and wants or solve problems.
6. The amount by which something is out of line.
7. Restrictions applied to geometric entities; for example, horizontal, parallel, perpendicular, and tangent.
11. Parallel to the X axis.
12. A distinctive attribute or aspect.
13. Make larger in area.
14. A limit to a design process. Constraints may be such things as appearance, funding, space, materials, and human capabilities. A limitation or restriction.
18. Attach or position securely.
20. A form of pictorial drawing in which all three drawing axes form equal angles of 120 degrees with the plane of projection.
21. A small angled surface formed between two surfaces.
22. To move in a circle about a central axis.
23. A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original. A model is often used to test ideas, make changes to a design, and to learn more about what would happen to a similar, real object.
26. Lines, planes, or surfaces side by side and having the same distance continuously between them.
