UG二次開發NXOpen-Python(三) 創建基本特征

創建基本特征

NXOpen對於特征的創建和修改利用該特征對應的builder來進行，創建一個基本特征（比如長方體、球體等等）的步驟如下：

1.創建一個builder

2.設置bulider的各個屬性

3.對builder進行'commit'

4.銷毀builder

例如，我們要創建一個長方體:

import NXOpen
import NXOpen.Features


def main():
    theSession = NXOpen.Session.GetSession()
    workPart = theSession.Parts.Work

    # 創建builder
    blockFeatureBuilder1 = workPart.Features.CreateBlockFeatureBuilder(
        NXOpen.Features.Block.Null)

    # 類型-原點和邊長
    blockFeatureBuilder1.Type = NXOpen.Features.BlockFeatureBuilder.Types.OriginAndEdgeLengths

    # 布爾
    blockFeatureBuilder1.BooleanType = NXOpen.Features.FeatureBooleanType.Create

    # 原點和邊長參數
    originPoint1 = NXOpen.Point3d(0.0, 0.0, 0.0)
    blockFeatureBuilder1.SetOriginAndLengths(originPoint1, "100", "100", "100")

    # commit
    block_feature = blockFeatureBuilder1.CommitFeature()

    blockFeatureBuilder1.Destroy()

if __name__ == '__main__':
    main()

打開NX12.0，新建模型，alt+F8，選擇文件，運行就能創建一個長方體
