Abstract
Abstract A teamwork CAD system which enables each designer to refer to the latest information on another part which has a relationship to the part under his control. A part shape data base stores the data on the shape of each part and a part control data base registers the designer who is designing or modifying each part and the designer who is referring to the part. A plurality of data processing units are allotted to a plurality of designers who are designing in parallel the parts of the object. When a designer (e.g., b) modifies the part Y under his control, the nature of the modification are transmitted to the part shape data base and the fact that modification has taken place and the nature thereof are transmitted to the terminal data processing unit of the designer (e.g., a ) who is referring to the part Y. The latest shape of the part Y is then displayed on the display unit of the designer a in approximate real time, so that the designer a can design the part X under his control with reference to the modified part Y.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
177 words
A teamwork CAD system for designing an object by a plurality of designers who design in parallel the respective parts of said object to which they are assigned using a plurality of data processing units, said system comprising: a part shape data base for storing the data on the shape of each part; a part control data base for registering the data on the designer who is designing or modifying each part at each point of time in correspondence with the data on the designer who is referring to said part; and a data control unit for updating the corresponding part shape data in said part shape data base in accordance with the nature of the modification when a part is modified in one of said data processing units, for retrieving and extracting the designer who is referring to said part which has been modified from said part control data base, and for transmitting the fact that said part has been modified and the nature of the modification to the data processing unit of the extracted designer.
Claim 2
Dependent Claim
62 words
A teamwork CAD system according to Claim 1, wherein said part control data base is capable of registering a plurality of designers who are referring to a part, and said data control unit transmits said fact and said nature of modification to said data processing units of all of said designers who are retrieved and extracted from said part control data base.
Claim 3
Dependent Claim
51 words
A teamwork CAD system according to Claim 1, wherein each of said plurality of data processing units includes a display unit which is capable of displaying the assembly of the part which is being modified and the part which is being referred to in the latest state on the same screen.
Claim 4
Dependent Claim
35 words
A teamwork CAD system according to Claim 1, further comprising a monitor for synthetically monitoring the progress of designing of all of said parts which are being designed using said plurality of data processing units.
Claim 5
Dependent Claim
38 words
A teamwork CAD system according to Claim 1, wherein said CAD system is a distributed CAD system in which said plurality of data processing units and said data control unit are connected with each other by a network.
Claim 6
Dependent Claim
38 words
A teamwork CAD system according to Claim 1, wherein said CAD system is a synthetic CAD system in which said plurality of data processing units and said data control unit are connected with each other by internal buses.
Claim 7
Dependent Claim
56 words
A teamwork CAD system according to Claim 1, wherein, every time a part is modified by one of said plurality of data processing unit, said data control unit retrieves and extracts the designer who is referring to said part and transmits said fact and said nature of modification to the data processing unit of said designer.
Claim 8
Dependent Claim
66 words
A teamwork CAD system according to Claim 1, wherein, when a part is continuously modified a number of times by one of said plurality of data processing units, said data control unit retrieves and extracts the designer who is referring to said part and transmits said fact and said nature of modification to the data processing unit of said designer at every predetermined period of time.
Claim 9
Dependent Claim
68 words
A teamwork CAD system according to Claim 1, wherein, when a part is continuously modified a number of times by one of said plurality of data processing units, said data control unit retrieves and extracts the designer who is referring to said part and transmits said fact and said nature of modification to the data processing unit of said designer at every predetermined number of times of modification.
Claim 10
Dependent Claim
176 words
A process for teamwork designing an object by a plurality of designers who design in parallel the respective parts of said object to which they are assigned using a CAD system provided with a part shape data base for storing the data on the shape of each part and a plurality of data processing units, said process comprising the steps of: registering the data on the designer who designs or modifiers each part at each point of time in a part control data base in correspondence with the data on the designer who is referring to said part; updating the corresponding part shape data in said part shape data base in accordance with the nature of the modification when a part is modified in one of said data processing units; retrieving and extracting the designer who is referring to said part which has been modified from said part control data base; and transmitting the fact that said part has been modified and the nature of the modification to the data processing unit of the extracted designer.
