Claim 5
Dependent Claim
34 words
A teamwork CAD system according to claim 1, further comprising a monitor for monitoring the progress of designing of all of said parts which are being designed using said plurality of data processing units.
Claim 6
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 7
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 8
Dependent Claim
53 words
A teamwork CAD system according to claim 1, wherein, every time a part is modified by one said plurality of data processing unit, said data control unit retrieves and extracts designer information referring to said part and transmits said fact and said nature of modification to the data processing unit of said designer.
Claim 9
Dependent Claim
64 words
A teamwork CAD system according to claim 1, wherein, when a part is continously modified a number of times by one of said plurality of data processing units, said data control unit retrieves and extracts designer information 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 10
Dependent Claim
66 words
A teamwork CAD system according to claim 1, wherein, when a part is continously modified a number of times by one of said plurality of data processing units, said data control unit retrieves and extracts designer information 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 11
Dependent Claim
210 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, an assembly structure data base storing structural data of the parts of the object, and a plurality of data processing units, said processing comprising the steps of: accessing data of the parts of the object from the assembly structure data base to determine relationships between parts; registering the data on the designer who designs or modifies 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 designer information referring to said part and designer 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 information.
Claim 12
Dependent Claim
210 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, an assembly structure data base storing structural data of the parts of the object, and a plurality of data processing units, said processing comprising the steps of: accessing data of the parts of the object from the assembly structure data base to determine relationships between parts; registering the data on the designer who designs or modifies 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 designer information referring to said part and designer 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 information.
