Abstract
Abstract Every type of change in a CAD generated object is automatically and chronologically protocoled so that the object directly includes an abstract description of the history of the object independent of the CAD module used. This is particularly advantageous with decentralized CAD systems in which several constructors/designers are working together on the same draft, but located in different places. At the end of a session, the object history, i.e. the changes which have taken place, are directly exported, together with the object data, into the destination system. The abstract description is in a form independent of the system used.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
84 words
A collaboration server supporting a computer-aided design (CAD) system, comprising: means for maintaining a database including CAD elements defining an object under design; means for receiving input commands from a plurality of remote client applications to modify said CAD elements; means for automatically logging discrete changes to said CAD elements resulting from said input commands in respective records; and means for generating a hypertext markup language (HTML) report from said records to enable user access to information related to changes to said CAD elements.
Claim 2
Dependent Claim
84 words
A collaboration server supporting a computer-aided design (CAD) system, comprising: means for maintaining a database including CAD elements defining an object under design; means for receiving input commands from a plurality of remote client applications to modify said CAD elements; means for automatically logging discrete changes to said CAD elements resulting from said input commands in respective records; and means for generating a hypertext markup language (HTML) report from said records to enable user access to information related to changes to said CAD elements.
Claim 3
Dependent Claim
28 words
The collaboration server of claim 1 wherein said means for automatically logging records values defining geometric characteristics of CAD elements when changes are made to said CAD elements.
Claim 4
Dependent Claim
44 words
The collaboration server of claim 1 further comprising: means for receiving information from a user related to a reason for a respective change to said CAD elements, wherein said means for automatically logging associates said received information and said respective change in a record.
Claim 5
Dependent Claim
27 words
The collaboration server of claim 1 further comprising: means for indicating in each record an identity of a user making a respective change to said CAD elements.
Claim 6
Dependent Claim
19 words
The collaboration server of claim 1 wherein said remote client applications communicate with said collaboration server via the Internet.
Claim 7
Independent Claim
90 words
A method for designing a computer-aided design (CAD) object, comprising: maintaining a database including CAD elements defining an object under design at a collaboration server; receiving, by said collaboration server, input commands from a plurality of remote client applications to modify said CAD elements; automatically logging discrete changes to said CAD elements as a result of said input commands in respective records; and generating, by said collaboration server, a hypertext markup language (HTML) report from said records to enable user access to information related to changes to said CAD elements.
Claim 8
Independent Claim
90 words
A method for designing a computer-aided design (CAD) object, comprising: maintaining a database including CAD elements defining an object under design at a collaboration server; receiving, by said collaboration server, input commands from a plurality of remote client applications to modify said CAD elements; automatically logging discrete changes to said CAD elements as a result of said input commands in respective records; and generating, by said collaboration server, a hypertext markup language (HTML) report from said records to enable user access to information related to changes to said CAD elements.
Claim 9
Dependent Claim
25 words
The method of claim 6 wherein said automatically logging records values defining geometric characteristics of CAD elements when changes are made to said CAD elements.
Claim 10
Dependent Claim
38 words
The method of claim 6 further comprising: receiving information from a user related to a reason for a respective change to CAD elements, wherein said automatically logging associates said received information and said respective change in a record.
Claim 11
Dependent Claim
25 words
The method of claim 6 further comprising: indicating an identity of a user responsible for a respective change to said CAD elements in each record.
Claim 12
Dependent Claim
18 words
The method of claim 6 wherein said remote client applications communicate with said collaboration server via the Internet.
Claim 13
Dependent Claim
117 words
A collaboration server, comprising: a database including computer-aided design (CAD) elements defining an object under design; and a collaboration server application for receiving input commands from a plurality of remote client applications to modify said CAD elements during a design session, wherein said collaboration server application identifies discrete changes to said CAD elements resulting from said input commands, creates a log of said discrete changes, and generates a hypertext markup language (HTML) report to enable user access to information related to changes to said CAD elements, wherein said HTML report is provided to each client to enable CAD users to review each change made to CAD elements during said design session while said design session is occurring.
Claim 14
Dependent Claim
117 words
A collaboration server, comprising: a database including computer-aided design (CAD) elements defining an object under design; and a collaboration server application for receiving input commands from a plurality of remote client applications to modify said CAD elements during a design session, wherein said collaboration server application identifies discrete changes to said CAD elements resulting from said input commands, creates a log of said discrete changes, and generates a hypertext markup language (HTML) report to enable user access to information related to changes to said CAD elements, wherein said HTML report is provided to each client to enable CAD users to review each change made to CAD elements during said design session while said design session is occurring.
Claim 15
Dependent Claim
28 words
The collaboration server of claim 11 wherein said collaboration server application automatically records values defining geometric characteristics of CAD elements when changes are made to said CAD elements.
Claim 16
Dependent Claim
36 words
The collaboration server of claim 11 wherein said collaboration server application receives information from a user related to a reason for a respective change to said CAD elements and includes said received information in said log.
Claim 17
Dependent Claim
28 words
The collaboration server of claim 11 wherein said collaboration server application indicates in said log an identity of a user making a respective change to said CAD elements.
Claim 18
Dependent Claim
19 words
The collaboration server of claim 11 wherein said remote client applications communicate with said collaboration server via the Internet.
