(1) obtain the detailed three-dimensional model of unit product;
(2) create new prt part, external envelope curved surface in detailed three-dimensional model, reference surface, reference point, reference frame etc. are copied in new prt part, in part, only comprise outside surface information and reference data, entity information in original part and internal information, can selectively copy as required;
(3), by newly-built prt part, by preserving the form of copy, create new unique file;
(4) the unique file title of newly preserving is changed into the three-dimensional model file name of unit product;
(5) three-dimensional model of the unit product of previous step being set up is assembled in general assembly (GA) model;
(6) in general assembly (GA) model, according to different demonstration demands, by the reduced representation in View Manager, temporarily do not need the model showing to get rid of other, for example, in general assembly (GA) model, contain below deck equipment model and above deck equipment model, in the time only need checking above deck equipment model, below deck equipment model is got rid of to a display module external equipment model, the internal memory that the model that reducing does not need to check takies by View Manager.。
For the three-dimensional model that has mechanism kinematic of complicated unit product, its lightweight display packing step is as follows:
(1) obtain the detailed three-dimensional mechanism model of unit product;
(2) the single prt part in mechanism model is created respectively to new prt part, external envelope curved surface in detailed three-dimensional model, reference surface, reference point, reference frame etc. are copied in new prt part, in part, only comprise outside surface information and reference data, entity information in original part and internal information, can selectively copy as required;
(3), by each prt part in newly-built mechanism model, by preserving the form of copy, create respectively new unique file;
(4) the unique file title of newly preserving is changed into the three-dimensional model file name of unit product;
(5) the prt part in the three-dimensional mechanism model of unit product is replaced with to the unique file of new preservation, and redefine annexation;
(6) three-dimensional model of the unit product of previous step being set up is assembled in general assembly (GA) model;
(7) in general assembly (GA) model, according to different demonstration demands, by the reduced representation in View Manager, temporarily do not need the model showing to get rid of other, for example, in general assembly (GA) model, contain below deck equipment model and above deck equipment model, in the time only need checking above deck equipment model, below deck equipment model is got rid of to a display module external equipment model, the internal memory that the model that reducing does not need to check takies by View Manager.
The beneficial effect that the lightweight display packing of complication system three-dimensional model of the present invention obtains is:
(1) by the lightweight display packing of complication system three-dimensional model, reduce model size, reduction takes up room to data platform, improves transfer rate;
(2) by the lightweight display packing of complication system three-dimensional model, greatly reduce the data volume of model, reduce the demand to hardware, increase work efficiency.
