Working accurately to dimensions will be an important part of most of your design projects. Complete this quick quiz to reinforce the tools and techniques you used.

1. How do you set up which modeling units (for example, mm or inches) you will use for a model?

   (a) In the Preferences > General Preferences window.

   (b) In the Windows > Information > Information Window.

   (c) In the Preferences > Construction Options window.

   (d) Type in the units, that is, ‘mm’ after you enter the value.

   (e) In the Construction > Grid Preset option window.

2. When projecting a curve, what determines the direction the curve is projected in?

   (a) You are prompted to type in the direction.

   (b) The active window: the curve will be projected perpendicular to the window view.

   (c) There is an option in the Project option window.

   (d) Hold down the key when selecting the curve.

   (e) It is determined by the mouse button you use to select the curve.

3. How do you modify the radius of an Arc or Circular Arc after you have created it.?

   (a) In the Attributes section of the Windows > Information > Information Window.

   (b) Use Object Edit > Query Edit and click the curve.

   (c) You have to delete the curve and create a new one.

   (d) Pick and scale the curve.

   (e) Use Locators > Measure > Distance to apply a dimension, and then change the number on the dimension.

4. Building geometry at the origin is a good idea because….

   (a) Grouping objects will create a pivot point at the origin.

   (b) The Edit > Duplicate > Mirror tools can be used to create symmetrical geometry.

   (c) The Layer symmetry tools can be used to work with symmetrical geometry.

   (d) You can use the center grid lines for snapping geometry to.

   (e) All of the above.

5. The Round tool has what advantage over the Surface Fillet tool?

   (a) It is more accurate

   (b) You can chain select a row of edges

   (c) It has Construction History

   (d) It automatically trims the surfaces

   (e) The Round tool can create a corner surface between three edges.
