Embodiment Construction

[0037] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0038] According to the modeling requirements of the panel and the geometric characteristics of the panel model, the panel is divided into margin area 1 and grid area 2. The margin area 1 is outside the grid area 2, and its structure is relatively simple, only auxiliary ribs and hoisting holes 7 are arranged symmetrically along the center line 4 of the upper surface of the margin area; while the grid area 2 has uniformly distributed grids The modeling process of unit 5 and relief hole 6 is relatively complicated.

[0039] After the division is completed, classify and analyze the structural geometric information of the panel model, including design parameters, feature dimensions, and reference dimensions, and sort out the parent-child relationship between the features included in the model and the driving relationship between parameters and dimensions .

Abstract

The invention provides a wallboard modeling method based on the UDF technology. UG software is adopted as a modeling platform, and a UDF library is set up; a parametric feature model of a wallboard is set up, the feature dimension variable and preliminary sketch dimension variable of the wallboard are determined, and the wallboard modeling method comprises the following modeling steps that a UDF is generated according to the feature dimension variable and preliminary sketch dimension variable of the wallboard; a user interface and a shortcut button for calling the generated UDF are developed through a UG/OPEN API module; a generated program is operated, and the needed wallboard model is generated by changing the values of all parameters in the user interface. According to the wallboard modeling method based on the UDF technology, the programming workload of library establishing is reduced, subsequent expansion and modification of the model in the library are convenient, the good user interface can be obtained, a system is connected with the model library, automatic normal data selection is achieved, the operation of calling the model in the library is convenient and fast, and subsequent modification and expansion of the content of the library are very convenient through the open model library structure.
