The present invention is described in further detail below by specific embodiment and with reference to accompanying drawing.
As shown in figure 1, a kind of bridge BIM model creation methods based on CATIA of the embodiment of the present invention, this method bag
Include：
Step 1, the basic data source of BOM tables is made：
According to bridge construction demand, assembly and zero component name and the level division of bridge BIM models are determined, is used
Mindjet MindManager softwares draw mind map, and .csv formatted files are exported in the form of outline, as BOM tables
Basic data source.
Mind map includes the assembly and zero component name and hierarchical relationship of bridge BIM models, wherein, assembly is bridge
Beam, zero component include the structure position of bridge, the partial structurtes of structure position, the thin portion structure of partial structurtes.
For mind map example as shown in Fig. 2 assembly is bridge, structure position includes superstructure, bearing, damping and flexible
Device, substructure and affiliated facility etc., assembly, structure position, partial structurtes and thin portion structure are in hierarchical relationship.Wherein, office
Portion's structure include main truss, bridge deck, common bearing and pinner, spherical bearing and pinner, damper, deck expansion installation, pier,
Basis, pumping equipment, pavement and railing etc., thin portion structure include montant, brace, top boom, lower boom, top bracing, lower flat
Connection, sway bracing, top cap, pier body, pile foundation etc..
Step 2, BOM tables are made：
BOM tables are divided into two forms of coding scheme and the encoding list, the two tables are arranged by EXCEL software editings
Lattice, level division is carried out to bridge BIM models using linear classification method, generates the title and numbering of assembly and zero component, it is clearly total
Into with zero component needed for the attribute information that is loaded into.
Wherein,
The encoding list include level, coding digit, level content, particular content and coding five row, each level it is specific
Content includes assembly and zero component name, is encoded to assembly coding corresponding with zero component.Coding in the encoding list is according to step
The level division relation of mind map and assembly and component name determine that level can be arranged to 1+N layer according to demand in rapid 1
Level, N is positive integer, is had in all levels and an only component serial number level, and component serial number level is component level, structure
The coding digit of part serial number level does not do hard requirement, can write according to demand.The encoding list example is as shown in figure 3, first
It is classified as level title, second is classified as level coding digit, and the 3rd is classified as level content (including assembly, structure position, local knot
Structure, thin portion structure etc.), the 4th is classified as particular content (including zero component such as assembly, structure position, partial structurtes, thin portion structure
Title), the 5th is classified as coding (coding of corresponding assembly and each zero component), sets 8 levels altogether, wherein, level 7 is arranged to
Component serial number level.
Coding scheme includes several levels, and level title, coding and attribute are included in each level, and level is entitled total
Into or zero component name, be encoded to corresponding to assembly or zero component and encode, attribute is the attribute that assembly or zero component correspondingly include
Information.When making coding scheme form, imported .csv formatted files are exported in step 1 as data source in EXCEL softwares
It is processed.Coding scheme example is as shown in figure 4, include the list of 1+N level composition, in each level, first row
Zero component name of level 1 is classified as the coding of level 1, second, the 3rd is classified as corresponding zero structure attribute.
Step 3, CATIA secondary development：
First by the second development interface of CATIA softwares, the BOM tables in steps for importing 2, structure tree and structure are automatically generated
Part file；
PRODUCT attributes and PART are automatically generated according to BOM tables by secondary development tool in CATIA softwares afterwards
Interior parameter attribute information, complete information addition.
Step 4, CATIA is modeled：
Based on the structure tree generated and component file, the establishment of CATIA geometrical models is carried out.
The content that BOM tables planted agent embodies in the present invention includes：(1) project level division (2) level coding (3) hierarchical relationship
The attribute that method of bisector framework (4) assembly and zero component numbering (5) assembly and each assembly of zero component name (6) and zero component are included
Information (IFD and drawing number in such as Fig. 4).The purpose that BOM tables make is to separate the geological information of model with non-geometry information,
Data combing, whole level division informations in a manner of method of bisector in clear and definite project model, generation are carried out by EXCEL softwares
Assembly and zero component name and numbering, while confirm the attribute information being loaded into needed for all units.This process ensure that level
Division relation is accurate and meets demand, and due to have cured assembly and zero component name and numbering generating mode, it can be ensured that numbering
With naming form unique and not repeating.The attribute information carried using EXCEL software finishing units, can be avoided in modeling process
In repeat, reduce modeling work amount, effective raising efficiency.
