Circle from Center Tool

The Circle from Center tool allows you to draw circles from the center.

To draw a circle with this tool, place the cursor in the drawing area at a location that will represent the center of the circle. Press the mouse button. Drag away from the starting point to enlarge the circle. The radius of the circle will show in the Edit Window, and you may tab into the Edit Window to edit the radius. Release the mouse button to complete the circle. The circle will be placed in the drawing.

Converting Objects to Ellipses

All of the circle tools can be used to convert a rectangle, arc or rounded rectangle to an ellipse. This includes Parallel Objects of the same base type. To do this, select one of the circle tools from the WildTools palette.

Press and hold down the Shift and Option keys. The cursor will change to a Yin-Yang cursor. Click on the object in the drawing. The object will be converted. Note that this technique can be used to 'close' an arc.

 


Fixed Circle Tool

The Fixed Circle tool allows you to place fixed-diameter circles by their center. The tool can adopt the diameter of any existing circle in the drawing, and this allows you to quickly copy circles without having to know the diameter of the circle.

In the tool's dialog, type the diameter.

To use the tool, click in the drawing.

Adopting a Diameter

An easy way to set the diameter of the circle is to adopt the diameter of any existing circle in the drawing. To adopt the diameter of a circle, press and hold down the Option key. The cursor will change to a Picklefork cursor. Click on any circle in the drawing. The tool will adopt the diameter of the circle.

 


Circle by Two Points Tool

The Circle by Two Points tool allows you to draw a circle by two points directly opposite each other on the circumference of a circle.

To draw with this tool, place the cursor in the drawing area at a location that will represent one of the points on the circle. Press the mouse button. Drag away from the starting point to enlarge the circle. You may tab into the Edit Window to edit the diameter of the circle. Release the mouse button when you have reached the desired end point. The circle will be placed in the drawing.

 


Circle by Three Points Tool

The Circle by Three Points tool allows you to draw a circle located by three points on the circumference of the circle.

To draw with this tool, place the cursor in the drawing area at a location that will represent one of the points on the circle. Press the mouse button. Drag away from the starting point to the second point and release the mouse button. Move the mouse to the third point and click. The circle will be placed in the drawing.

 


Ellipse Tool

The Ellipse tool allows you to draw ellipses. Two methods of drawing are available: corner-to-corner or along-the-middle.

In the tool's dialog, choose whether the tool will draw from corner-to-corner or along-the-middle.

To draw an ellipse from corner-to-corner, place the cursor in the drawing area at a location that will represent one corner of a rectangle enclosing the ellipse. Press the mouse button. Drag away from the starting point. You may use the Shift key to constrain the angle of the corner-to-corner line--when constrained to 45° this will give you a circle. You may press the Option key to toggle between drawing from center and normal drawing. You may tab into the Edit Window to edit the height and width of the ellipse. Release the mouse button to complete the ellipse.

The along-the-middle method allows an ellipse to be drawn by a line in the middle and then expand the width of the ellipse on either side of the line. To draw an ellipse along-the-middle, place the cursor in the drawing area at a location that will represent the starting point of the line down the middle of the ellipse. Press the mouse button.

Drag away from the starting point. You may use the Shift key to constrain the angle of the line. You may tab into the Edit Window to edit the length and angle of this line. Release the mouse button to complete this line. Move the mouse to the side of the line (shown in gray) to expand the width of the ellipse. You may tab into the Edit Window to edit the width. Click the mouse to complete the ellipse. The ellipse will be placed in the drawing.

 


Rotated Ellipse Tool

The Rotated Ellipse tool allows you to draw an ellipse at any angle.

To draw an ellipse with this tool, place the cursor in the drawing area at a location that will represent one corner of a rectangle enclosing the ellipse. Press the mouse button. Drag away from the starting point to draw a line along one side of the enclosing rectangle. This line may be at any angle. You may use the Shift key to constrain the angle of the line. You may press the Option key to toggle between drawing from center or normal drawing. When you select drawing from center, you are drawing not only the line, but also the ellipse from the center. You may tab into the Edit Window to edit the angle of this line. Release the mouse button to complete this line.

Move the mouse away from the line to set the height and width of the ellipse. You may tab into the Edit Window to edit the height and width of the ellipse. Click the mouse to complete the ellipse. The ellipse will be placed in the drawing.
