Activity 2.1 Isometric Sketching
Activity 2.1 Conclusion Questions
1. What are the advantages and disadvantages to using an isometric pictorial compared to using an oblique pictorial in technical drawings?
- The difference between the two types of sketches would be that; isometric sketches show a equal measure or realistic view of an object, while with oblique sketches the depth that is presented can sometimes be distorted (depending on the view).
2. What is the difference between a two-dimensional sketch and an isometric sketch?
- The variation between a two-dimensional sketch and a isometric sketch would be that an isometric sketch is a much more detailed or realistic view of the object. While the two-dimensional image is flat and can not give much detail as to its dimensions other than the ones presented, the isometric sketch presents a visual representation of what that same object would look like in an equal measurement sketch.
3. Why do designers use tonal shading?
- Designers utilize the effect of toner shading to give the object a sense of lighting and to distinguish the direction of the image in most cases.

Activity 2.2 Perspective Sketching
Activity 2.2 Conclusion Questions
1. What is a vanishing point?
- A vanishing point is a point where a perspective ending seems to disappear or for ever go on.
2. Aside from the number of vanishing points, what is the difference between a one-point, two-point, and three-point perspective sketch?
- The major difference between these three types of sketching would be the angles in which they are perceived. A one point drawing while easy to create is awkward is visualization. A two point drawing is the most common perspective drawing. Last but not least a three point drawing is a drawing that presents a birds eye view to the spectator while allowing the most sides or most amount of coverage seen of the image or object.
3. How does a perspective drawing differ from an isometric drawing of the same object? When would you use a perspective view instead of an isometric drawing?
- An isometric drawing is different to a perspective drawing due to their difference in accuracy. While an isometric image focuses on its measurements and accuracy, a perspective drawing emphasizes the most natural position or eye pleasing view.

Activity 2.3 Glass Box
Activity 2.3 Conclusion Questions
1. How do you determine the orientation of orthogonal projections in a multi-view drawing?
- The most often used views of a multi-drawing are the Front, Top, and Right views. These are most likely to be the guidelines to orient yourself when examining a multi-view drawing:–Most natural position or use
–Shows best shape and characteristic contours
–Longest dimensions
–Fewest hidden lines
–Most stable and natural position
2. How would you describe the geometric relationship that exists between the adjacent views of a multi-view drawing?
- The lines of sight that are perpendicular to the plane of the feature show the relationship with the object of a muti-view drawing.
3. Why is it important to lay out a multi-view sketch with points and construction lines before drawing object lines?
- It is essential to lay out points and construction lines in a sketch to insure that the image can maintain consistency through out the sketch. By doing this the artist insures that the image will have accuracy.

Activity 2.4
Activity 2.4 Conclusion Questions
1. What is the purpose of construction lines? Object lines?

Activity 3.7 Conclusion Questions
1. Describe the difference between population standard deviation and sample standard deviation. Describe a scenario in which you would use each.
- A population standard deviation is measure of the entire population. So if you are trying to measure the number of people in your class who have older siblings you would survey the entire class so it is a population standard deviation. If you ask a question about the number of people who have older siblings in Ontario it would almost be impossible to survey the entire population so it would be a sample. Thus a sample standard deviation.
2. Which type of standard deviation (population or sample) is displayed when the Data Analysis Tool is used within Excel?
-The population standard deviation is used in excel's data analysis tool.
3. How do the statistics that you calculated using Excel compare to the statistics that you calculated by hand for the connector depth data?
-Well for one the data was much more easily calculated, two the data was much more specific and accurate.
4. Other than the calculation of statistics, how could an engineer use a spreadsheet application to increase efficiency?
-An engineer would use spreadsheet applications for various things, to keep inventory of shop items, or measurement recordings for various projects. They could also be used to store employee information that deals with their company if they posses one.

Activity 3.8 Conclusion Questions
1. Why is it important to know the accuracy and precision of a measuring device?
-To ensure that the measurements are precise and consistent.
2. Do you think that the dial caliper manufacturer’s claim that the accuracy of the instrument is ±.001 is appropriate? Why or why not?
-Yes, because the caliper design does have the capability to measure to the thousandths decimal point.
3. Do you think that either of the dial calipers needs to be adjusted in order to accurately display measurements? Explain.
-Well to begin you must adjust the dial caliper to 0 to ensure that the measurement is from the the 0 mark and to provide an accurate measure.

Activity 4.1 g Model Creation
Activity 5.1 Calculating Properties Shapes
Conclusion Questions
1. What is the difference between a circle and an ellipse?
-A circle has an equal radius all around while an ellipse differs in the x and y axis.
2. What is the difference between an inscribed and a circumscribed shape?
-The difference between an inscribed shape and a circumscribed shape is that an inscribed shape is formed inside of another shape, while a circumscribed shape is formed around the outside of another shape.
3. Why is it impossible for a triangle to contain a 180° angle?
-It is impossible for a triangle to have an angle of 180 degrees because in its totality it is 180 degrees. therefore it could not possibly be a triangle if it had an angle of 180 degrees.
4. How is a rhombus similar to a square?
-a rhombus and square are similar because of their parallel lines. they both have two sets of parallel lines.
5. What is the difference between a right, acute, and obtuse triangle?
- A right angle is created by having an angle that is exactly 90 degrees. An acute angle is formed by an angel that ranges from 1 to 89 degrees. an obtuse angle is larger than 90 but less than 180 degrees.

File Type: | idw |
Conclusion Questions
1. What is a geometric constraint?
-it is a non-numerical relationships between the parts of a geometric figure. Examples include parallelism, perpendicularity, and concentricity.
2. What are the different types of geometric constraints that are applied to sketches, and what are their functions?
-Perpendicular is a constraint that causes lines or axes of curves to meet at right angles.
Parallel causes two or more lines or ellipse axes to be equidistant from each other.
Tangent is used to cause two arcs or a line and an arc to intersect at a single point perpendicular to the arc's radius.
Coincident fixes two points together, or fixes a point to a curve.
Concentric causes two or more arcs, circles, or ellipses to share the same center point.
Colinear causes two lines or ellipse axes to lie along the same line.
Horizontal causes lines, ellipse axes, or pairs of points to lie parallel to the X axis of the sketch coordinate system.
Vertical causes lines, ellipse axes, or pairs of points to lie parallel to the y axis of the sketch coordinate system.
Equal forces line segments to be the same length and arcs or circles to have the same radius.
Fix constrains points or curves to a specific point on the sketch coordinate system.
Symmetry causes selected lines or curves to become symmetrically constrained about a selected line.
3. Define “tangent”.
-
a. Sketch a line tangent to two circles.
-
b. Sketch three circles such that all circles are tangent to the other two.
