Units : MM
Step 1) Inscribed Triangle . Dimensioned to 22. Centered at origin
Step 2) Make 1 vertex of triangle vertical with the origin. This will define the shape
Step 3) This is what your shape should now look like :
Step 4) Use the scissor tool to delete the top 3rd of the circle
Step 5) Connect the 2 points (make sure it’s defined)
Step 6) Perform 2 extrudes (25 and 35). :
Step 7) Fillet as shown:
Step 8) Add a shell:
Step 9) Final product:
Workspace Units: MM
Step 1) Create a new sketch on the front plan and create the following sketch. All share centered at the origin:
(Click image to enlarge)
Step 2) Extrude 1:
Step 3) If sketch 1 is hidden, make sure to show it
Step 4) Extrude 2:
Step 5)Fillet :
Step 6) Add a chamfer:
Result
Step 1) Create a 25, 30 , 40 and 42 MM circles all centered at the orig
Step 2) Add a single circle on the right that has a radius of 35.
Step 3) connect centers with construction line. Make sure that the blue lines are coincidental to the circles
tip: if you draw a line , you can use the ‘q’ button to change it to a construction line!
Step 4) Make the blue lines symmetric to the construction line and at a 9 degree angle
Step 5) The center of the circles should be dimensioned to 44:
Step 6) Each part of the circle on the left should be an extrude. The outermost starts at 10MM, then 15MM, 20, 25 MM:
Step 7) Connect the two end circles with a 2 MM extrude. The right side is 25 MM:
Step 8)create the variable as shown below:
Step 9) Add a fillet to all the circles edges. Set its amount to the variable len as shown. This video shows you how to use a variable and then change the variable:
Set document to MM
Step 1) Make a circle, centered at origin with a diameter of 30. Then create a circle with a diameter of 20 to its right.
Step 2) Connect the 2 circles with 2 lines coincident on to both circles. You should see the highlighted constraints when you mouseover either of them:
Step 3) Dimention the angle between the 2 lines to be 12 degrees. Make sure it’s the ANGLE , not the distance. If you’re not sure how to do that, watch this short animation.
Step 4) Create a construction line connecting centers, then make the two lines symmetric to that line:
Step 5) Add the 2 dimensions shown . The shape should now be fully defined (all black)
Step 6) Extrude the middle part by 15 . Symmetric extrude and then add a 1 MM Fillet:
Step 7) Extrude th e2 circle by 30 MM (no pic. You should be able to do this on your own)
To dimension and angle in onShape, you click on each side after the dimension tool
Workspace Units: MM, use the front plane
Step 1) Create 2 line segments, centered at the origin (as always) and dimension them to 10 MM each
step 2) These should be angled at 45 degrees
Step 3) Add a 12 and 9 MM segments :
Step 4) Dimension the 2 angles to 140:
step 5) Connect with a tangent arc
Step 6) Add a 5 MM symmetric extrude
Step 7) Fillet the Edge of Extrude 1 in these 3 places:
Step 8) Final Filletted version:
Step 1) Open up a new document.
Step 2) Create a line of length 2 from the origin and line of length 3 from the origin; something like . Their exact angle doesn’t matter, just something like :
Step 3) Create a 45 degree angle between the 2 line segments:
Step 4) Connect the end points with a tangent arc:
Step 5) Dimension the center of that arc with the point of top line as shown:
Step 6) Create an inscribed circle as shown :
Step 7) Create a symmetric extrude
Step 8) Finished product. Notice how the symmetric extrude goes up and goes down:
Step 1)
lines should be larger on right side
Step 2) Make the blue lines symmetric to the construction line
Step 3) Click on the top line and construction and dimension the 1.5 degree angle
Step 4) dimension the 2 left side points to 1.5
Step 5) Resulting picture :
Complete all the methods below. When you are done, copy and paste the testmethods.v5.1 into your class and run it to see if you have any obvious errors. The above code does not guarantee you a 100 but will help catch most of the common errors that students make.
Note: You may not use any external libraries (like Java.Arrays etc )or import any code. Everything can be done with just loops and variables.
int sumEveryN(int[] nums, int n)
Description:This method returns the sum of every n elements of nums ..
| Method Call | return value/output |
| sumEveryN( {1 , 2 , 3 , 4 }, 2 ) | 4( ie 1 +3) |
| sumEveryN( {13 , 42, 15, 33 , 44 , 16 , 52} ,3) | 98 ( ie 13 + 33+ 52) |
String[] doubleArr(String[] strs)
Description: This method returns a new version of strs in which each element now appears twice. This can be done with a for-each loop, which I believe is easier and more intuitive.
| Method Call | return value/output |
| doubleArr( {“a”,”b”,”c”} ) | {“a”,”a”,”b”,”b”, “c” , “c”} |
| doubleArr( {“math”,”ware”,”house”,”.com” }) | {“math”,”math”,”ware”,”ware”,”house”,”house”,”.com”, “.com”} |
int indexOf5(int[] nums )
Description:This returns the index of the first occurrence element 5 or -1 if 5 does not appear anywhere in the array.
| Method Call | return value/output |
| indexOf5( { 2 , 3 , 5 , 4 } ) | 2 |
| indexOf5( { 2 , 3 , 5 , 4, 5 } ) | 2 |
| indexOf5( { 2 , 3 ,7 , 4, 3, } ) | -1 |
More Sample calls and return vals
int indexOf(int[] nums, int num)
Description: This method returns the index value of the first appearance of num or -1 if num is not an element of nums .
| Method Call | return value/output |
| indexOf( {6,4 ,7,3, 4 }, 4) | 1 |
| indexOf( {6,4 7 ,3,2,7}, 7) | 2 |
| indexOf( {6,4 ,2,3}, 22) | -1 |
int[] randos(int start, int end, int howMany)
Description: This method returns an array of random numbers between [start,end] . Note make sure that each element in the new array attempts to make a new random int. Use Math.random() , do not use any other mechanism for finding a random number.
double meanBetween(int[] nums, int min, int max)
Description: This method returns the mean of nums ; however, this method only counts values within the range (min,max) as shown in the examples below:
