Draft Ellipse/sv

Description
The Ellipse tool creates an ellipse in the current work plane by entering two points, defining the corner of a rectangular box in which the ellipse will fit. It takes the linewidth and color previously set on the Tasks tab.



How to use

 * 1) Press the  button, or press  then  keys
 * 2) Click a first point on the 3D view, or type a coordinate
 * 3) Click a second point on the 3D view, or type a coordinate

Options

 * To enter coordinates manually, simply enter the numbers, then press between each X, Y and Z component.
 * Press or click the checkbox to check/uncheck the  button. If continue mode is on, the Ellipse tool will restart after you give the second point, allowing you to draw another ellipse without pressing the Ellipse button again.
 * Press while drawing to force snapping your point to the nearest snap location, independently of the distance.
 * Press while drawing to constrain your second point horizontally or vertically in relation to the first one.
 * Press or the  button to have the ellipse to appear as a face after it has been closed. This simply sets the View->Property of the ellipse to "Flat lines" or "Wireframe", so it can easily be changed later.
 * Press or the  button to abort the command.
 * Ellipses, when in "Flat Lines" display mode, can display a hatch pattern, by setting their "Pattern" property below.

Properties

 * : The major radius of the ellipse
 * : The minor radius of the ellipse
 * : Specifies a hatch pattern to fill the ellipse with
 * : Specifies the size of the hatch pattern

Scripting
The Ellipse tool can by used in macros and from the python console by using the following function:
 * Creates an ellipse object with given major and minor radius.
 * If a placement is given, it is used.
 * If facemode is False, the ellipse is shown as a wireframe, otherwise as a face.
 * Returns the newly created object.
