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 Draft Ellipse button, or press E then L 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 ENTER between each X, Y and Z component.
  • Press T or click the checkbox to check/uncheck the Continue 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 CTRL while drawing to force snapping your point to the nearest snap location, independently of the distance.
  • Press SHIFT while drawing to constrain your second point horizontally or vertically in relation to the first one.
  • Press I or the Filled 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 ESC or the Cancel button to abort the command.
  • Ellipses, when in "Flat Lines" display mode, can display a hatch pattern, by setting their "Pattern" property below.

Properties

  • DataMajor Radius: The major radius of the ellipse
  • DataMinor Radius: The minor radius of the ellipse
  • ViewPattern: Specifies a hatch pattern to fill the ellipse with
  • ViewPattern Size: Specifies the size of the hatch pattern

See also Draft Pattern page.

Scripting

The Ellipse tool can by used in macros and from the python console by using the following function:

 makeEllipse (majorradius, minorradius, [placement], [facemode])
  • 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.

Example:

 import Draft
 myEllipse = Draft.makeEllipse(4,2)
