- Use the front plane and the make a 3 point arc centered at the origin
- Picture:
- Use the dimension tool to set the radius to 20 mm :
- Resulting shape :
- create 2 lines that are attached to the circle and that meet at a point outside the circle. Dimensions don’t matter, yet, for these. Your document should look similar to (does not have to be exact
- :
- Use the Tangent tool to make both lines tangent . You must select both the circle and the line as shown below:
- Create a construction line from the end points of the arc:
- Create a Rectangle, as shown in the video below. Watch the end carefully for how to make the points coincident. Your interconnected shape should move as shown below:
- Use the Dimension tool to make sure that the height of the rect is 65 MM :
- Add a midpoint to the bottom of the rectangle:
- Make a Circle centered at that midpoint
- Dimension the bottom circle so that its diameter is 35 :
- As you can see only the top tangent line is blue. So that’s the last item to dimension! Dimension it to 42 :
- Use the trim tool to remove the top half of the circle and its diameter line:
- Now your turn. In the same document. Create a complex separate shape. This shape should include a minimum of 5 simple shapes. 1 of the shapes must be an arc or a semicircle. All of the shapes must be dimensioned.

Constraints Additional Practice
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.
