CADPart
Overview
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 requires at least level 2, its default container field is children. It is available from X3D version 3.1 or higher.

Fields
SFNode [in, out] metadata NULL [X3DMetadataObject]
Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.
Hint
SFString [in, out] name “”
Optional name for this particular CAD node.
Hints
- Well-defined names can simplify design and debugging through improved author understanding.
- X3D Scene Authoring Hints, Naming Conventions
Warning
- name field is not included if this instance is a USE node, in order to avoid potential mismatches.
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
- 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] center 0 0 0 (-∞,∞)
Translation offset from origin of local coordinate system, applied prior to rotation or scaling.
Hint
- The order of operation is first apply the center offset, then scaleOrientation and scale, then rotation, then restore the center offset, then translation.
SFBool [in, out] visible TRUE
Whether or not renderable content within this node is visually displayed.
Hints
- The visible field has no effect on animation behaviors, event passing or other non-visual characteristics.
- Content must be visible to be collidable and to be pickable.
SFBool [in, out] bboxDisplay FALSE
Whether to display bounding box for associated geometry, aligned with world coordinates.
Hint
- The bounding box is displayed regardless of whether contained content is visible.
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.
Hints
- Can be useful for collision computations or inverse-kinematics (IK) engines.
- Precomputation and inclusion of bounding box information can speed up the initialization of large detailed models, with a corresponding cost of increased file size.

SFVec3f [ ] bboxCenter 0 0 0 (-∞,∞)
Bounding box center accompanies bboxSize and provides an optional hint for bounding box position offset from origin of local coordinate system.
Hints
- Precomputation and inclusion of bounding box information can speed up the initialization of large detailed models, with a corresponding cost of increased file size.

MFNode [in] addChildren
Input field addChildren.
MFNode [in] removeChildren
Input field removeChildren.
MFNode [in, out] children [ ] [CADFace]
Grouping nodes contain an ordered list of children nodes.
Hints
- Each grouping node defines a coordinate space for its children, relative to the coordinate space of its parent node. Thus transformations accumulate down the scene graph hierarchy.
- InputOnly MFNode addChildren field can append new X3DChildNode nodes via a ROUTE connection, duplicate input nodes (i.e. matching DEF, USE values) are ignored.
- InputOnly MFNode removeChildren field can remove nodes from the children list, unrecognized input nodes (i.e. nonmatching DEF, USE values) are ignored.

Advice
Hints
- CADPart is often a child of CADAssembly node.
