Clicking on the upper Shape/Create new shape/Circle menu item activates one of the special editing features used to create a shape of the line type on a vector layer. A circular line shape created with the Circle feature is composed of 64 sequentially numbered vertices with 63 straight line segments connecting them.

To create a circular line shape on a vector layer (based on a center point and a radius)

1. Activate (highlight) the layer in which the circle is to be created. Do this by clicking on its name in the Legend.
2. Use the Zoom mode, Zoom extended mode and Drag mode to adjust the extent visible on the Map area to cover the area where you would like to create the circle.
3. Click on the upper Shape/Create new shape/Circle menu item.
4. Within the Map area move the mouse pointer over the desired point and click - this fixes the center point of the circle.
5. Adjust the length of the radius by moving the mouse pointer in any direction.
6. Click again to finish drawing the circle.

The icon on the Standard toolbar; if not visible click on the rightmost icon on the same toolbar and then on the upper Circle item on the drop-down list.

• To create a different shape of a line type, use one of the following features: Line, Line 90°, Line free, Closed line, Closed line 90°, Rectangle [line], Rectangle rotated [line], Circle 3point base [line].
• A different method of creating an approximation of a circle is available with the Circle 3point base [line] feature.
• To create a circular polygon, use the Circle [polygon] or Circle 3point base [polygon] feature.

• To edit an existing shape, use the Edit shape feature.
• To remove a shape from a vector layer, use the Delete shape feature.

• If the edited layer is stored in the ArcView Shape File (SHP) format of the type different than line then this feature will be inactive.
• While adjusting the length of the radius the perimeter and the radius are dynamically illustrated on the Map area.
