• Centre, Radius – Indicate the centre point and the radius of the circle.
• Point, Centre – Indicate a point on the circumference and the centre point.
• 2 Points – Indicate two points on the circle's circumference.
• 3 Points – Indicate three points on the circle's circumference.
• Between 2 Items, Radius – Indicate two items between which to draw a circle, and specify the radius.
• Between 3 Lines or 2 Lines 1 point – Indicate three lines, or two lines and one point, between which to draw a circle.

Centre, Radius

Draw a circle by indicating the centre point and the radius of the circle.

1. Indicate centre point: Press Enter to use the position of the current control as the centre point.
2. Indicate radius: Press Enter to use the current mouse position. The circle is drawn using the specified radius.

Point, Centre

Draw a circle with the indicated point on the circumference and the centre point of the circle.

1. Indicate point on circumference: Press Enter to use the position of the current control as the circumference point.
2. Indicate centre point: Press Enter to use the current mouse position. The circle is drawn using the indicated points.

2 Points

Draw a circle through two indicated points on the circumference of the circle.

1. Indicate first circumference point: Press Enter to use the position of the current control as the first circumference point.
2. Indicate second circumference point: Press Enter to use the current mouse position. You can also enter the position of the second point relative to the first point. The circle is drawn through the indicated points

3 Points

Draw a circle through three indicated points on the circumference of the circle.

1. Indicate first circumference point: Press Enter to use the position of the current control as the first circumference point.
2. Indicate second circumference point: Press Enter to use the current mouse position. A temporary line is drawn between the first and the second indicated points. This temporary line can be useful for indicating the third circumference point.
3. Indicate third circumference point: Press Enter to use the current mouse position. The circle is drawn through the indicated points. The temporary line is now deleted.

Between 2 Items, Radius

Draw a circle between two indicated items and enter the radius. You can draw the circle between two lines, two circles, two arcs, or between a line and a circle, or between a line and an arc.

1. Indicate first item: Click on a line, circle, or arc.
2. Indicate second item: Click on the second item.
3. Indicate radius: Enter a positive radius. A circle that has a tangent with the indicated items and the specified radius is drawn.

Between 3 Lines or 2 Lines 1 point

Draw a circle between three lines, or between two lines and one reference point. The drawn circle has three circumference points, either on the indicated lines or on the lines and at the reference point. The circle cannot be created if the lines are parallel to each other.

1. Point to first line: Click on a line.
2. Point to second line: Click on the second line.
3. Point to third line or use hotkey to select a point: Click on the third line or select a point with a keyboard shortcut. A circle that has a tangent with the indicated lines and point is drawn.
