Description

The Ellipse tool creates an ellipse in the current work plane by entering two points, defining the corners of a rectangular box in which the ellipse will fit. It uses the Draft Linestyle set on the Draft Tray.

How to use

  1. Press the Draft Ellipse.png 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

The ellipse can be turned into an elliptical arc after creation, by setting its first angle and last angle properties to different values.

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 toggle continue mode. If continue mode is on, the Ellipse tool will restart after you finish the shape, allowing you to draw another one without pressing the tool button again.
  • Press L or click the checkbox to toggle filled mode. If filled mode is on, the ellipse will create a filled face (DATAMake Face True); if not, the ellipse will not make a face (DATAMake Face False).
  • 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 Esc or the Cancel button to abort the current command.

Properties

  • DATAMajor Radius: The major radius of the ellipse
  • DATAMinor Radius: The minor radius of the ellipse
  • DATAMake Face: Fills the ellipse with a face
  • 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)
