Abstract

Methods and program products for presenting a view of physical element, the physical element represented in a computer aided design (CAD) model, and integrating a presentation of structural reinforcement of the physical element into the view of the physical element.

Claims

1. A computer-implemented method, comprising:

providing a view of a physical element, the physical element represented in a computer aided design (CAD) model;

determining a structural reinforcement appearance for the physical element where the appearance includes an arrangement of bars in one or more layers as determined by a structural analysis of the CAD model;

integrating the appearance of the structural reinforcement into the view of the physical element, where the bars do not have corresponding physical elements in the CAD model;

receiving a modification of the physical element; and

modifying the appearance of the structural reinforcement to reflect the modification to the physical element, where the modifying is performed by one or more processors.

2. The method of claim 1, where:

the appearance of the structural reinforcement is apparent in the view of the physical element when the view exposes no interior portion of the physical element.

3. The method of claim 1, where:

the appearance of the structural reinforcement is apparent in the view of the physical element when the view exposes one or more interior portions of the physical element.

4. The method of claim 1, where:

the appearance of the structural reinforcement accommodates one or more openings in the physical element.

5. The method of claim 1, where:

the appearance of the structural reinforcement represents a concrete or a frame reinforcement.

6. The method of claim 1, where:

the physical element is one of;

a wall, a floor slab, and a column.

7. A system, comprising:

one or more computers; and

a computer-readable medium coupled to the one or more computers having instructions stored thereon which, when executed by the one or more computers, cause the one or more computers to perform operations comprising;

providing a view of a physical element, the physical element represented in a computer aided design (CAD) model;

determining a structural reinforcement appearance for the physical element where the appearance includes an arrangement of bars in one or more layers as determined by a structural analysis of the CAD model;

integrating the appearance of the structural reinforcement into the view of the physical element, where the bars do not have corresponding physical elements in the CAD model;

accepting a modification of the physical element;

modifying the appearance of the structural reinforcement to reflect the modification of the physical element;

and

where the modifying is performed by one or more processors.

8. The system of claim 7, where:

the appearance of the structural reinforcement is apparent in the view of the physical element when the view exposes no interior portion of the physical element.

9. The system of claim 7, where:

the appearance of the structural reinforcement is apparent in the view of the physical element when the view exposes one or more interior portions of the physical element.

10. The system of claim 7, where:

the appearance of the structural reinforcement accommodates one or more openings in the physical element.

11. The system of claim 7, where:

the appearance of the structural reinforcement represents a concrete or a frame reinforcement.

12. The system of claim 7, where:

the physical element is one of;

a wall, a floor slab, and a column.

13. A computer storage medium encoded with a computer program, the computer program comprising instructions that when executed by a data processing apparatus to perform operations comprising:

providing a view of a physical element, the physical element represented in a computer aided design (CAD) model;

determining a structural reinforcement appearance for the physical element where the appearance includes an arrangement of bars in one or more layers as determined by a structural analysis of the CAD model;

integrating the appearance of the structural reinforcement into the view of the physical element, where the bars do not have corresponding a physical elements in the CAD model;

receiving a modification of the physical element; and

modifying the appearance of the structural reinforcement to reflect the modification to the physical element.

14. The computer storage medium of claim 13, where:

the appearance of the structural reinforcement is apparent in the view of the physical element when the view exposes no interior portion of the physical element.

15. The computer storage medium of claim 13, where:

the appearance of the structural reinforcement is apparent in the view of the physical element when the view exposes one or more interior portions of the physical element.

16. The computer storage medium of claim 13, where:

the appearance of the structural reinforcement accommodates one or more openings in the physical element.

17. The computer storage medium of claim 13, where:

the appearance of the structural reinforcement represents concrete or frame reinforcement.

18. The computer storage medium of claim 13, where:

the physical element is one of;

a wall, a floor slab, and a column.
