- Create the exact diagram below in a new .plan file.
- add 3 furniture items t the Family room
- add 2 furniture items to the Dining room
- Use the dimensions and room names


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:
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:
Array Loops
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:
Old versions:
Step 1) Create a rectangle and dimension to 30 by 50 as shown
Step 2) Create your first extrude . Use 30 mm as shown in the video below:
Step 3) Let’s make it a shell :
Step 4) Now let’s try something different. Delete the shell and delete the extrude, then delete the sketch the start all over.
Step 5) Draw a circle and a line. Don’t worry to much about the dimensions. Just make it look close to this :
Step 6) Create a revolve using the line as the axis as shown in this video:
Step 7) Mess around with the 3-d shapes and do something else…make another revolve..or another extrude or one of the others. Submit a screenshot of this below the do now
Step 1) Create a new sketch on the front plane. There should only be 1 sketch that you use
Step 2) Create a circle and then use the “coincident ” button to center it on the origin by clicking on the origin, the center of the circle :
Step 3) make its radius 15 MM by using the dimension tool
Here’s what your document should now look like :
Step 4) Do the same thing with a second circle . Make its radius 30
Step 5) Make a line that touches the circle, anywhere. Like the picture below:
Step 5) Find the “tangent line” constraint (this might be a dropdown)
Step 6) Here’s how you create a tangent line.
Click the circle , click the line you made, then press “tangent line ”
Step 7) Make a construction line from the tangent line to the bottom
Step 8) Make a second tangent line as shown:
Step 8) Dimension both tangent lines so that they are 60 MM each
Step 9) Add a second shape that is dimensioned.
