# 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.

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

**2. A term used to describe the creation of an exact part replicated on the other side of a drawn axes.**

**3. The line where two pieces of material come together.**

**4. A three-sided polygon.**

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

**6. 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.**

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

**16. A special type of quadrilateral with its opposite sides parallel to each other - referred to as a parallelogram - and with all of its angles as right angles.**

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

**18. A perfectly round object where all points are equidistant from a fixed point.**

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

**20. In drawing software - parts of a two-dimensional drawing that attach surfaces together when the pattern is folded into a three-dimensional shape.**

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

**22. A file in the listing of the files stored in memory usually on a hard disk of a computer.**

**23. A helix or conical shape that is found on the external shaft or the internal surface of a cylindrical hole.**

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

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

**26. The use of computer software applications that allows the user to visualize an idea in a three-dimensional format.**

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

**28. Of or exhibiting equality in dimensions or measurements.**

**29. A curved surface formed at the interior intersection of two or more surfaces of an object.**

**30. (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.**

**31. The process of stretching or lengthening the measurement of a detail on a drawing.**

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

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

**34. A right angle projection wherein the views on a drawing are drawn at right angles to one another.**

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

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

**40. In a computer-aided drawing program - a feature created by adding depth to a sketched profile of an object.**
