# CADPart

CADPart is an atomic part that defines both coordinate-system location and the faces that constitute a part in a Computer-Aided Design (CAD) model. CADPart contains multiple CADFace nodes that make up a single part.

The CADPart node belongs to the **CADGeometry** component and its container field is *children.* It is available since X3D version 3.1 or later.

# Fields

### SFNode [in, out] **metadata** NULL [X3DMetadataObject]

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

### SFString [in, out] **name** ""

Optional name for this particular CAD node.

#### Warning

Name is not included if this instance is a USE node.

### SFVec3f [in, out] **translation** 0 0 0 (-∞,∞)

Position (x, y, z in meters) of children relative to local coordinate system.

#### Hint

The order of operation is first apply the center offset, then scaleOrientation and scale, then rotation, then restore the center offset, then translation.

### SFRotation [in, out] **rotation** 0 0 1 0 [-1,1] or (-∞,∞)

Orientation (axis, angle in radians) of children relative to local coordinate system.

#### Hint

The order of operation is first apply the center offset, then scaleOrientation and scale, then rotation, then restore the center offset, then translation.

### SFVec3f [in, out] **scale** 1 1 1 (0,∞)

Non-uniform x-y-z scale of child coordinate system, adjusted by center and scaleOrientation.

#### Hint

The order of operation is first apply the center offset, then scaleOrientation and scale, then rotation, then restore the center offset, then translation.

### SFRotation [in, out] **scaleOrientation** 0 0 1 0 [-1,1] or (-∞,∞)

Preliminary rotation of coordinate system before scaling (to allow scaling around arbitrary orientations).

#### Hint

### SFVec3f [in, out] **center** 0 0 0 (-∞,∞)

Translation offset from origin of local coordinate system, applied prior to rotation or scaling.

#### Hint

### SFVec3f [ ] **bboxSize** -1 -1 -1 [0,∞) or −1 −1 −1

Bounding box size is usually omitted, and can easily be calculated automatically by an X3D player at scene-loading time with minimal computational cost. Bounding box size can also be defined as an optional authoring hint that suggests an optimization or constraint.

#### Hint

Can be useful for collision computations or inverse-kinematics (IK) engines.

### SFVec3f [ ] **bboxCenter** 0 0 0 (-∞,∞)

Bounding box center: optional hint for position offset from origin of local coordinate system.

### MFNode [in] **addChildren**

Input field addChildren.

### MFNode [in] **removeChildren**

Input field removeChildren.

### MFNode [in, out] **children** [ ] [CADFace]

Input/Output field children.
