Simply, can only from top to bottom, the parameter transmitting between partial model, plate is to drive cabinet body structure to change.On father's model not
The parameter that submodel can be established, being not achieved makes the transmitting of parameter from bottom to up, tells what model submodel all employs to father
Parameter, the parameter come up of submodel transmitting can report the information of any submodel, such as size, area, material, pattern,
So that the controllable parameter of all components can be obtained on one node of father's model.It is another there is no global parameter system conveniently: institute
Meaning global parameter had passed through the multiple current values for having used the global parameter of a global state modulator both to unified driving cabinet
Body structure.Other one does not have parameterized template system conveniently: so-called parameterized template system, both collects the parameter having built up
For template, it is introduced directly into the creation parameter for not needing repeatability in use next time.
In terms of the renewal process of model: when parameter change, more new logic is in terms of going in the form of tree structure+chained list
The data for calculating all parts drive sub- grade to update in layer from top to bottom.I.e. before the update the structure of model be it is fixed,
User cannot arbitrarily modify structure.
On the whole not in real time to the error detection of entire model.It is any to lead to model i.e. when user is in modeling process
The change for constructing failure, cannot detected and inform user.

Many kinds of parameters type and Value Types are supported in the creation of parameter；Wherein parameter type can be shaping, floating type, character string, boolean
Type, more Boolean types, material, profile, pattern etc., Value Types can be with sections, incremental, fixed value, formula, compound formula etc..
Above-mentioned parameter can be with directly creation can also create in global parameter list on model in modeling process.And
Afterwards parameterized template can be set by the parameter created.It can join from global parameter list or from template when so modeling
These parameters are taken out in ordered series of numbers table directly to use.The parameter in another special source we become Report Parameters: subassembly
Parameter is attached on father's model.Illustrate when subassembly addition reference name below.
The source of subassembly: 1. directly add from base components, these base components include underlying parameter model, auxiliary
Help structure.Wherein underlying parameter model includes: the ginseng that special-shaped plate, setting-out, grid, spline curve etc. can be various bases
Numberization model, these underlying parameter models be in system it is pre-added, have specific parameter.Supplementary structure: including wheel
Wide limitation, straight line adsorption line, right angle adsorption line, interior sky, door opening, interference region, conduit coupling etc. are used for Computer Aided Design and life
The some structures produced.2. the parameterized model having had been built up can be used.
Subassembly can be set reference name and such as be provided with C, and subassemblies other in this way and father's model can be taken [email protected]
To the W parameter of C component.To achieve the purpose that parameter is transmitted between the parts and transmitted from bottom to top.
The building of parameterized model: addition parameter and addition subassembly and by between expression formula control parameter and parameter according to
Bad relationship, the parameter relationship dependency between component and component.#W+ C.D has been write such as an expression formula, that is, used W parameter and
The D parameter of C component.
Parameterized model is constructed, core is to construct function.One function has into ginseng and function internal logic, enters changing for ginseng
Become the result for affecting function.Component is to call in addition in a function body using the parameterized model having had been built up
One function.
On this basis, such as Fig. 2, the technical solution of the invention is as follows, provides a kind of modeling of household parameterized model
