Abstract

Methods for CAD modeling and corresponding systems and computer-readable mediums. A method includes receiving a CAD model including a selection of multiple adjacent web faces of the CAD model and at least one datum plane of the CAD model that intersects the web faces, receiving a selection of a joggle side of the CAD model with respect to the datum plane, and receiving an offset direction and an offset depth value corresponding to each selected web face. The method includes creating at least one joggle feature in the CAD model by moving a portion of each of the selected web faces on the joggle side of the CAD model according to the respective offset directions and the depth values, including creating at least one runout for each selected web face at the datum plane, to produce a modified CAD model. The method includes storing the modified CAD model. The multiple adjacent web faces can include intermediate web faces.

Claims

1. A method performed by a data processing system and comprising:

receiving a CAD model including a selection of multiple adjacent web faces of the CAD model and at least one datum plane of the CAD model that intersects the web faces;

receiving a selection of a joggle side of the CAD model with respect to the datum plane;

receiving an offset direction and an offset depth value corresponding to each selected web face;

creating at least one joggle feature in the CAD model by moving a portion of each of the selected web faces on the joggle side of the CAD model according to the respective offset directions and the depth values, including creating at least one runout for each selected web face at the datum plane, to produce a modified CAD model; and

storing the modified CAD model.

2. The method of claim 1, wherein selected web faces include at least one intermediate web face.

3. The method of claim 1, wherein the datum plane intersects the web face, and the portion of the web face on the opposite side of the datum plane from the joggle side is designated as a stationary portion.

4. The method of claim 1, wherein the CAD model includes twin datum planes, and the joggle side is automatically determined as the portion of the web face between the twin datum planes.

5. The method of claim 1, wherein the modified CAD model includes a bend region connecting two of the moved portions of the selected adjacent web faces.

6. The method of claim 1, wherein creating at least one runout for the joggle feature includes creating intersecting runouts for multiple adjacent web faces.

7. The method of claim 1, wherein the selected web faces include end web faces and at least one intermediate web face.

8. A data processing system comprising:

a processor; and

an accessible memory, the data processing system particularly configured to

receive a CAD model including a selection of multiple adjacent web faces of the CAD model and at least one datum plane of the CAD model that intersects the web faces;

receive a selection of a joggle side of the CAD model with respect to the datum plane;

receive an offset direction and an offset depth value corresponding to each selected web face;

create at least one joggle feature in the CAD model by moving a portion of each of the selected web faces on the joggle side of the CAD model according to the respective offset directions and the depth values, including creating at least one runout for each selected web face at the datum plane, to produce a modified CAD model; and

store the modified CAD model.

9. The data processing system of claim 8, wherein selected web faces include at least one intermediate web face.

10. The data processing system of claim 8, wherein the datum plane intersects the web face, and the portion of the web face on the opposite side of the datum plane from the joggle side is designated as a stationary portion.

11. The data processing system of claim 8, wherein the CAD model includes twin datum planes, and the joggle side is automatically determined as the portion of the web face between the twin datum planes.

12. The data processing system of claim 8, wherein the modified CAD model includes a bend region connecting two of the moved portions of the selected adjacent web faces.

13. The data processing system of claim 8, wherein creating at least one runout for the joggle feature includes creating intersecting runouts for multiple adjacent web faces.

14. The data processing system of claim 8, wherein the selected web faces include end web faces and at least one intermediate web face.

15. A non-transitory computer-readable medium encoded with executable instructions that, when executed, cause one or more data processing systems to:

receive a CAD model including a selection of multiple adjacent web faces of the CAD model and at least one datum plane of the CAD model that intersects the web faces;

receive a selection of a joggle side of the CAD model with respect to the datum plane;

receive an offset direction and an offset depth value corresponding to each selected web face;

create at least one joggle feature in the CAD model by moving a portion of each of the selected web faces on the joggle side of the CAD model according to the respective offset directions and the depth values, including creating at least one runout for each selected web face at the datum plane, to produce a modified CAD model; and

store the modified CAD model.

16. The computer-readable medium of claim 15, wherein selected web faces include at least one intermediate web face.

17. The computer-readable medium of claim 15, wherein the datum plane intersects the web face, and the portion of the web face on the opposite side of the datum plane from the joggle side is designated as a stationary portion.

18. The computer-readable medium of claim 15, wherein the CAD model includes twin datum planes, and the joggle side is automatically determined as the portion of the web face between the twin datum planes.

19. The computer-readable medium of claim 15, wherein the modified CAD model includes a bend region connecting two of the moved portions of the selected adjacent web faces.

20. The computer-readable medium of claim 15, wherein creating at least one runout for the joggle feature includes creating intersecting runouts for multiple adjacent web faces.
