Description
Technical field
The present invention relates to the CAD field, in particular to the CAD 3D file management method.
Background technology
Cad technique is from the history of existing three more than ten years so far that is born, and CAD system is developed to 3 D intelligent design, parametrization design direction by simple two-dimensional graphics.(Product Data Management, PDM) system also progressively develops into the product design process management system of supporting collaborative design and concurrent engineering from the document management at initial stage to product data management.
The PDM system except that need to the data element and between static data such as relation manages, also need the change procedure of management product data.After using PDM, uniform data leaves in the electronic warehouse, and in life-cycle processes to various states should be arranged, every kind of state is to there being corresponding operation.
The state of 3D data in life cycle has: { New, Checked in, Checked out, Release, New Release, Obsolete}.New represents just to set up but does not also deposit data in the electronic warehouse in; The Checked in data in the electronic warehouse of representing to check in; Checkedout represents the data that detect from electronic warehouse; Release represents the data issued, and the data under this state form a fixing version, can not make an amendment again; New Release is illustrated in the redaction that generates on the basis of existing released version; Obsolete represents filing data.Each state is used for the change of executing state to corresponding operation of the same name should be arranged.
Compare with PDM towards the plane drawing towards the PDM of three-dimensional CAD, its difference is: 1. the difference of method for designing causes the management difference to design process; 2. the complexity of design result is different; 3. the degree utilized of design result difference.
In realizing process of the present invention, the inventor finds not set up Managed Solution effectively at the CAD 3D file in the prior art, but various CAD 3D files are stored in this locality dispersedly, relation each other lacks to be analyzed, writes down and safeguard, thereby after causing the product data amount constantly to increase, various errors take place easily, and for example version confusion, main accessory are asynchronous etc.
