SolidWorks API SelectByID2 方法

Question

有一种更有效的方法使用GetSelectedObjectCount()和GetSelectionPoint2()方法来获取可以与SelectByID2 方法。下面方法的问题是每个点的创建在特征树中既不省时也不整洁。一有时间就会更新这个帖子。

感谢您的理解。

我最近开始在 SolidWorks 中使用 VBA 进行一些编程，我想编写一个宏。现在的目标是从 selected 面和点（从边派生）创建一个参考平面。提醒一下，创建参考平面的方法是 InsertRefPlane，它需要 selection 通过 SelectByID2 方法完成。

到目前为止，我已经设法保存了面和点对象的句柄，但我还没有成功地使用 SelectByID2 方法。 selected 的对象变为 deselected。

value = instance.SelectByID2(Name, Type, X, Y, Z, Append, Mark, Callout, SelectOption)

我试过select只是一张脸，但我做不到。此外，我已经使用 SetEntityName 方法重命名了面部属性，并提供了它，但它没有设法 select 它。

能否请您分享一下如何创建参考平面的想法？不一定非要有脸和 edge/mid-point.

提前致谢。

编辑 1： 为了进一步说明，我向 selection 添加了两个对象（面和边），我想将它们正确地用于 select 具有 SelectByID2 的对象以用于 InsertRefPlane。我添加了下面的代码。

我的想法是：

我有面和边的手柄，但我可以将它们用于正确的 selection 和 SelectByID2 吗？
我可以在 selected 面和边缘上创建一个参考点来以某种方式识别面吗？
SelectByRay 似乎可行，但它需要对面法线进行一些计算，因此，如果可用，我会尝试一些其他“更简单”的方法。 编辑 2：我的脸不是平面的，所以我不能请求正常属性的脸。
Edit 3: 看来这一切都归结为识别对象名称和类型是解决问题的方法。这可能是一个解决方案，但我愿意接受另一个解决方案，如果可能的话会更容易。我们可以在使用适当的 Selection 方法之一时创建一个参考点，因为它们的名称是已知的，我们可以将它们用于 SelectbyID2 方法。完成后 post 解决方案。

Answer 1

我不为你工作的原因可能有很多。没有你完整的代码，很难帮到你。

如果您的 selection 被删除select，可能是因为您将“Attempt”设置为 False。此外，第一个 selection 的“Mark”需要为“0”，第二个需要为“1”。看InsertRefPlane

中的备注和例子

获得代码基础的最佳方法是开始录制宏，手动插入平面，然后停止并编辑代码。

此外，SelectByID2 并不是 select 一张脸的唯一方法，还有 SelectByRay, or cycle through all the entities with GetFirstFace / GetNextFace or GetFaces 可以找到你想要的那个。

Answer 2

大部分细节都在我的问题中，最后编辑的是我如何解决它。方法是：

从 SelectionManager 获取对象（如面或边）的句柄
创建所选对象的实体对象，这允许您使用 Select4 方法
现在您可以创建参考几何图形，并获得可以与 SelectByID2 方法一起使用的名称属性

我在另一个型号上试过了，但不能保证它也适用于你。

Answer 3

Actually it looks like there might be issues because the CAD model is imported and faces are faces are non-planar.

嗨马里奥，

您可以使用以下方法检查所选面是否为平面：

Face.IGetSurface().IsPlane()
