UG二次开发NXOpen-Python(三) 创建基本特征

创建基本特征

NXOpen对于特征的创建和修改利用该特征对应的builder来进行，创建一个基本特征（比如长方体、球体等等）的步骤如下：

1.创建一个builder

2.设置bulider的各个属性

3.对builder进行'commit'

4.销毁builder

例如，我们要创建一个长方体:

import NXOpen
import NXOpen.Features


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

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

    # 类型-原点和边长
    blockFeatureBuilder1.Type = NXOpen.Features.BlockFeatureBuilder.Types.OriginAndEdgeLengths

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

    # 原点和边长参数
    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()

打开NX12.0，新建模型，alt+F8，选择文件，运行就能创建一个长方体
