Description
Describes structs specific to AcBr classes.
Structures
| Structure | Description |
|---|---|
 AcBr | The AcBr structure contains definitions for the Autodesk Boundary Representation library, which are shared between internal and third-party developers. This structure holds error codes that are specific to AcBr, using a starting base of 3000 to avoid conflict with AutoCAD, the Mechanical API, or the Mechanical Desktop.An enumerated field for relation of bounded geometry to topology (for example, point in Brep, curve on face) is also included. The kInside and kOutside values are relative to the object's topological boundary. |
| AcBrMassProps | The AcBrMassProps struct contains the volume, the mass (equal to the volume unless the density is specified as anything other than unity), the centroid (center of gravity), the radii of gyration (square root of the moments of inertia divided by the rigid body mass), the rigid body moments of inertia (mass times the square of the axial radius), the products of inertia (mass times the distance from the centroid to the Y,Z plane times the distance from the centroid to the X,Z plane), the principal moments at the centroid (derived from the products of inertia), and the principal axes at... more |
