Description
Inserts a subtractive ellipsoid in the active Body. Its shape is subtracted from the existing solid.
On the left: active body (A) shown in grey and subtractive ellipsoid (B) shown in transparent red; result on the right.
Usage
- Press the
Subtractive Ellipsoid button. Note: the Subtractive Ellipsoid is part of an icon menu labelled Create an subtractive primitive. After launching FreeCAD, the Subtractive Box is the one displayed in the toolbar. To get to the Ellipsoid button, click on the down arrow besides the visible icon and select Subtractive Ellipsoid in the menu. - Set the Primitive parameters and Attachment.
- Click OK.
- An Ellipsoid feature appears under the active Body.
Options
The Ellipsoid can be edited after its creation in two ways:
- Double-clicking it in the Model tree, or by right-clicking and selecting Edit primitive in the contextual menu; this brings up the Primitive parameters.
- Via the Property editor.
Properties
- ДанныеAttachment: defines the attachment mode as well as the Attachment Offset. See Part EditAttachment.
- ДанныеLabel: label given to the Ellipsoid object. Change to suit your needs.
- ДанныеRadius1: the radius value along the ellipsoid's vertical axis; by default, parallel to the Z-axis.
- ДанныеRadius2: the radius value along the ellipsoid's length; by default, parallel to the X-axis.
- ДанныеRadius3: the radius value along the ellipsoid's width; by default, parallel to the Y-axis. At the default value of zero, the ellipsoid forms an oblate spheroid.
- ДанныеAngle1: (labelled V parameter in the Primitive parameters) lower truncation of the ellipsoid, parallel to the circular cross section (-90 degrees in a full spheroid)
- ДанныеAngle2: (unlabelled in the Primitive parameters) upper truncation of the ellipsoid, parallel to the circular cross section (90 degrees in a full spheroid).
- ДанныеAngle3: (labelled U parameter in the Primitive parameters) angle of rotation of the elliptical cross section (360 degrees in a full spheroid).
