Creating a Fully Defined Circle

In this section we will sketch a circle to help understand the difference between a fully defined and an under defined Part .
Start a New Part drawing and click the Top plane tool as defined in Figure 1 .
1. Click the Sketch tab. (It may already be activated.)
Click the Circle tool.

2. Locate the cursor on the origin, click the mouse, and drag the cursor away from the origin center point.
3. Note that the Coincident relationship symbol appears next to the origin, indicating that the center point of the circle is located on the origin.

4. Click the mouse to define a sketch radius for the circle.

This is a temporary radius, that is, a sketched radius, and is not the final radius. The circle will be blue, indicating that it is not fully defined. See Figure 2 .
