# 3d Computer Modeling

**Instructions:**

- Answer 50 questions in 15 minutes.
- If you are not ready to take this test, you can study here.
- Match each statement with the correct term.
- Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

**9. The lines or points belonging to the same line or an extension of that line.**

**10. A solid body with six equal square sides or faces.**

**11. A frame of reference or alignment that is usually a position relative to a compass direction.**

**12. A line parallel to the horizon.**

**13. A detail created that forms an angle at the intersection of two planes.**

**14. The two points that are fixed together with the use of a constraint.**

**15. A line - point - edge - surface - or other detail used to establish a known location.**

**16. To compel or force points - lines - or parts to behave in a certain manner.**

**17. The process of creating a reproduction or likeness of something.**

**18. A feature created by the reproduction of the initially drawn feature in a circular pattern.**

**19. A hole with a tapered top so that the top of the head of an inserted screw will be flush with the outside surface.**

**20. A closed curve with coplanar points at the same distance from the center point.**

**21. Any physical portion of an object - such as a hole or fillet.**

**22. The limitation of measurement that is placed on a part of a product.**

**23. A three-sided geometric figure having all sides equal.**

**24. The two points that are fixed together with the use of a constraint.**

**25. A term used to describe two things having the same value or size.**

**26. In drawing software - a term describing the movement of the endpoint of a line to a new location.**

**27. (1) A hole consisting of two depths so that the top of the head of an inserted bolt or screw will be flush with the outside surface. (2) A bit for enlarging the upper part of a hole.**

**28. A four-sided polygon with equilateral sides and 90-degree interior angles.**

**29. A line type used to show the location of the centers of arcs and circles or a drawn detail.**

**30. Arcs and circles that have a common origin or center.**

**31. A closed geometric figure in a plane formed by connecting line segments endpoint to endpoint with each segment intersecting exactly two others. Polygons are classified based on the number of line segments used - such as triangle - quadrilateral - pen**

**36. A three-dimensional representation of an object.**

**37. A closed plane figure formed by the plane section of a right angled cone.**

**38. A drawing that shows the interior details along a cutting plane.**

**39. The line drawn from a detail to the dimension line on a drawing to show the area of the measurement.**

**40. A closed curve with coplanar points at the same distance from the center point.**

**41. A term describing a detail that is upright or perpendicular to the horizon.**

**42. A term describing parts or features being equal distances apart at every point.**

**43. (1) Computer Aided Drawing (2) The use of a computer to create drawings.**

**44. (1) A hole consisting of two depths so that the top of the head of an inserted bolt or screw will be flush with the outside surface. (2) A bit for enlarging the upper part of a hole.**

**45. The limitation of measurement that is placed on a part of a product.**

**46. A process used to change details in a drawing after initial creation.**

**47. A closed curve with coplanar points at the same distance from the center point.**

**48. An effective visual means of communication that utilizes freehand drawing. A collection of freehand drawings that communicate an idea. There are three types: program - design - and thumbnail.**

**49. A drawing that describes more fully the attributes of a part.**

**50. A linear measurement that shows the extents of something - such as width - height - or length.**
