Create an Ellipse

Modeling: CurvesCurvesEllipse

In this dialog box you may specify the dimensions of an ellipse either numerically or by using expressions. The construction will always be performed in the currently active coordinate system.

Each ellipse will be assigned to a curve.

Within its curve each item is identified by a unique name. The curve item can be addressed by this name for subsequent editing operations.

As soon as the curve item is defined it will appear in the main plot window and on the navigation tree.

The picture below shows an ellipse defined in global coordinates:

Name

Specify the unique name for the ellipse.

Xradius, Yradius

Specify valid expressions for the radii of the ellipse in global coordinates. Please note that these entries only appear when the global coordinate system is currently active.

Uradius, Vradius

Specify valid expressions for the radii of the ellipse in local coordinates. Please note that these entries only appear when a local coordinate system is currently active.

Xcenter, Ycenter

Specify valid expressions for the center point coordinates of the ellipse in global coordinates. Please note that these entries only appear when the global coordinate system is currently active.

Ucenter, Vcenter

Specify valid expressions for the center point coordinates of the ellipse in local coordinates. Please note that these entries only appear when a local coordinate system is currently active.

Segments

Specify a valid integer expression for the segmentation of the ellipse.

Curve

Select the curve to which this ellipse item will be assigned from the list of previously defined curves or enter a new name.

Press this button to finally create the ellipse.

Preview

Press this button to create a preview image of the ellipse. This option is very useful to check the settings before you actually create the ellipse.

Cancel

Closes this dialog box without performing any further action.

Help
