13.5-2 Question 9 has the answer as 4587FN, Print shows this as 64587FN

13.5-1 Might be a bit of a reach asking for sheet size. Covered in lesson 1 or 2 but have only used A, B, C,. D since.

11.8-2 Max for Item !, the number 2 is the only value left and checks as the correct answer with the minimum being .24485. This answer should be slightly larger than .25"

11.8-1 #1-4 are currently case sensitive. Can lower case only answers be added as acceptable? also, #5 Correct answer shows 2.751/2.752 Print shows Dimension as 2.751-2.750.

10.10-2 Question 1 asks for minimum depth. Answer says .86" Depth is called out as 2.55 +/- .02" on the print. can this be split up into two exercises? One to identify from the print and one to match letters?

10.10-3 Title Block is hard to read even when enlarged. Assuming tolerance is +/-.01 on 2 place and +/-.005 on 3 place?

10.10-2 Question 3-5 refer to the Neck. Several components of this part could be called a "Neck" since that is somewhat of a universal term for tapers and undercuts. Can this be changed to Thread Relief Groove to avoid confusion?

10.10-1 Question 10 asks about what UNC stands for. UNC should be a 3 word answer of Unified National Coarse. Two word example would be National Coarse instead of Unified Coarse. It is assumed that all threads are "Unified" threads.

8.96-2 Answer for A should be 0.9" not 1.9" Tolerance for A to D should be +/- .03" not +/-.01". Tolerance for B to C should be +/-.01". Tolerance for D to H should be +/- .04".Tolerance for G to H should be +/- .07".

8.9-1 D to H should be +/- .02" not .04" as the 2.70" and the 6.00 are both +/- .01"

7.4-3 Question 12 Rev level should be D not M4-.7

7.4-2 Unsure of where to get information. Guessed at most sizes. A,B,C,D can all nearly be interchanged based on scale but print is not to scale. Unsure why one is .128 and the other is .13 2.25-2.00 /2 =.125" Where did the .003" come from?

3x dia .203 thru all Dia 1.125 B.C. bolt circle needs to me 1.125 radius as it is outside the 6-32 holes that are on a 2" B.C.

6.5-2 Question 2, dimension B. I get .87 and the answer says .868. (3.5-1.76)/2=.87.

6.5-2 number 9, Dim I 1.75-.62-.5=.62, correct answer checks as .625" Print dimensions do not add up to .625 unless we assume the nominal size instead of the given numbers. Students will most likely use given information and not assume the nominal of 5/8".

6.5-2 Cannot find Dim. C and H is not in RED.

Dimensions A, B, and C are not in red like the rest. Hard to find on the print.

5.3-1 allows for entering dimensions as .375, .500, .257 etc. with no zero needed left of the decimal as in exercise 5.2-2. Please make this consistent from one exercise to the next. Preferred as no zero needed as shown in the print on exercise 5.2-2

Exercise 5.2-2 When numbers are less than 1, zero is needed for a significant digit to get the correct answer even though print clearly states dimension as .50". Typing .50" is marked incorrect.

Chapter 3, Line Quiz 1, Item N. Points to the edge of the center mark for the hole in View A-A. Could be confused as N is being defined as the face. Is there another way of showing a center line instead of a center mark? Perhaps in view A-A or B-B using the counterbored/tapped hole with a dimension to the center of the part?

Chapter 3, Line Quiz 1, Item K Correct answer shows a Viewing Plane Line. K appears to point to either the Extension line for the 1" Dimension.

Chapter 3, Quiz Question 1, Correct answer of Viewing-Plane Line is listed two times in the answer list. Checking one shows an incorrect answer, checking the other shows a correct answer.
