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
- There are several ways to invoke the tool:
- Press the
Subtractive Ellipsoid button. Note: the Subtractive Ellipsoid is part of an icon menu labelled Subtractive Primitive. After launching FreeCAD, the Subtractive Box is the one displayed in the toolbar. To get to the Ellipsoid, click on the down arrow besides the visible icon and select Subtractive Ellipsoid in the menu.
- Select the Part Design → Subtractive Primitive →
Subtractive Ellipsoid option from the menu.
- Press the
- 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 Tree View, or by right-clicking and selecting Edit Primitive in the context menu; this brings up the Primitive Parameters.
- Via the Property View.
Properties
- DataAttachment: defines the attachment mode as well as the Attachment Offset. See Part EditAttachment.
- DataLabel: label given to the Ellipsoid object. Change to suit your needs.
- DataRadius1: the radius value along the ellipsoid's vertical axis; by default, parallel to the Z-axis.
- DataRadius2: the radius value along the ellipsoid's length; by default, parallel to the X-axis.
- DataRadius3: 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.
- DataAngle1: (labelled V parameter in the Primitive Parameters) lower truncation of the ellipsoid, parallel to the circular cross section (-90 degrees in a full spheroid)
- DataAngle2: (unlabelled in the Primitive Parameters) upper truncation of the ellipsoid, parallel to the circular cross section (90 degrees in a full spheroid).
- DataAngle3: (labelled U parameter in the Primitive Parameters) angle of rotation of the elliptical cross section (360 degrees in a full spheroid).
