Create a Circle

You can create a circle.

  1. From the Sketch section of the action bar, click Circle .
  2. Locate the circle's center.

    You can:

    • Click anywhere in the work area.
    • If you know where this point must be located, use Tools Palette which now displays following value boxes:

      • H: horizontal

      • V: vertical

      • R: radius

  3. In the H and V boxes in the Tools Palette, enter the coordinates for the circle's center.
  4. In the R box in the Tools Palette, enter the radius value.
    The circle is created.

    Tip: The constraints are assigned to this circle on the condition that you have entered the coordinate values in the boxes (you did not create the circle by clicking).

Create a Circle Reusing a Circle Radius Value

You can create a circle using the radius of the previously created circle.

  1. Click Circle .
  2. Right-click the first circle and select Parameter > Copy Radius.
  3. Click to indicate the second circle's location or use Tools Palette to specify the its center.


    The new circle is automatically created with the radius of the circle first created.
