Abstract A method for interfacing between a product planning conceptual design tool and a CAD/CAM environment allows an indented bill of materials to be imported to the CAD/CAM environment while retaining the characteristics as a primitive text file. The conceptual design tool uses a sketch sheet approach on a computer display to enter the functional design of a new or modified product, thereby encouraging the designer to use a top down approach to the design process. The user keys in item information, and the system automatically draws a hierarchical tree structure on the computer display. The system then automatically generates an indented bill of materials which is stored in a graphics standard file that retains the character of text primitives. From this file an image of the bill of materials can be displayed in the CAD/CAM environment. The designer can use this image as an aid in the design process. Item names and numbers can be copied from the displayed bill of materials to the CAD/CAM image. The bill of materials can also be edited in the CAD/CAM environment and the edited bill of materials can then be reconstructed in the conceptual design tool for use in the continuing design and planning process.
A method for interfacing between a conceptual design tool and a CAD/CAM environment for implementing product design on a computer, comprising the steps of: prompting a user to input functional product structure data; capturing the product structure data input by the user in a database; generating a hierarchical tree structure of the product structure and displaying the tree structure to the user as the product structure data is captured in the database; generating an indented bill of materials for the product from the product structure data captured in the database and storing the indented bill of materials in the database; storing the indented bill of materials in a graphics standard as a primitive text file; displaying an image of the indented bill of materials in the CAD/CAM environment while retaining the character of the displayed image as a primitive text file.

Claim 3
Dependent Claim
46 words
The method recited in claim 1 further comprising the step of splitting a CAD/CAM display screen into a text portion and a graphics portion, the step of displaying the image of the indented bill of materials being performed by displaying said image in said text portion.
Claim 4
Dependent Claim
64 words
The method recited in claim 1 wherein display means are provided for displaying a text image and for displaying a graphics image, said method further comprising the steps of: loading said bill of materials for display as text image on said display means; selecting text from said bill of materials text image; and importing selected text from said text image to said graphics image.
Claim 5
Dependent Claim

The method recited in claim 3 further comprising the steps of: drawing items listed in said text image of said bill of materials, said drawing step being performed in said graphics image; and incorporating said text imported to said graphics image with drawn items in a graphics file.
Claim 6
Dependent Claim
53 words
The method recited in claim 3 further comprising the steps of: modifying items in the text image of said bill of materials; updating said bill of materials stored in said graphics standard as a primitive text file; and using the primitive text file, updating, the indented bill of materials stored in said database.
