我正在尝试使用 Python 3 在 SolidWorks 中自动创建一些零件（这里没有问题）并将这些零件添加到装配体中（这是我的问题）。
运行以下代码时没有任何错误，但部件未添加到程序集中。任何想法？

创建一个零件
jacket = PartModel(cs=4., thk=0.5, c_opening=60., dj=50., name="Jacket")
jacket.create_cring()
创建第二个
liner = PartModel(cs=3., thk=0.5, c_opening=60., dj=50., name="Lining")
liner.create_cring()
创建装配体
