Solidworks VBA 跳过空数组

Question

我正在创建一个用于渲染 Solidworks 模型的宏。它旨在呈现程序集中的所有配置。我正在处理的一段代码必须提取所有配置的质量并将其放在渲染名称的末尾。对于大多数配置，这都有效。

只有在装配体中没有模型的情况下，这意味着质量属性中没有可用数据，才会给我一个错误：类型不匹配。代码如下所示（错误的位置用**突出显示：

End Sub

所以我想知道是否有可能跳过提取错误配置的属性（如果可能的话，在渲染名称中将其替换为“0”）。

希望你能帮助我。 提前致谢！

如果质量为零，您似乎需要跳到下一次迭代。 要跳到下一个迭代，下面是您在 VBA 中的操作方法。

For i = 1 To 3 

 If SomeConditionTrue Then 
  GoTo NextIteration
 End If 

 NextIteration:
Next i
