# 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 three-sided geometric figure having all sides equal.**

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

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

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

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

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

**7. A line drawn between extension lines where the measurement is noted.**

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

**9. A polyhedron with two faces (bases) that are congruent and parallel polygons and whose other faces (lateral faces) are parallelograms formed by segments connecting the corresponding vertices of the bases.**

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

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

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

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

**15. 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**

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

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

**23. A solid pointed figure with a circular or elliptical base.**

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

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

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

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

**28. In drawing software - the surface that is being drawn or projected onto to show the idea being conveyed.**

**29. A term used to describe locking a point to a position relative to the sketch coordinate system.**

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

**31. In the use of a three-dimensional computer software drawing program - the drawing limit refers to the amount of the drawing area.**

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

**33. In drawing software - a term describing the creation of a feature by rotation of a two-dimensional profile about an axis.**

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

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

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

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

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