如何使用 Solidworks VBA/API 创建"flip offset"参考平面

Question

我正在尝试创建两个与原点等距离的平行参考平面。我可以创建一个正平面:

Dim swDoc As SldWorks.ModelDoc2
Dim distance As Double
Dim BoolStatus As Boolean
Dim swLeftFace As SldWorks.RefPlane
Dim swRightFace As SldWorks.RefPlane
BoolStatus = swDoc.Extension.SelectByID2("Right Plane", "PLANE", 0, 0, 0, False, 0, Nothing, swSelectOption_e.swSelectOptionDefault)
Set swRightFace = swDoc.FeatureManager.InsertRefPlane(swRefPlaneReferenceConstraints_e.swRefPlaneReferenceConstraint_Distance, distance, 0, 0, 0, 0)

但是，我不能创建负平面。当"distance"是负的，它的值为0。这样就形成了一个与原点重合的平面。我已经尝试了"swrefplanereferenceconstraint_optionflip"的一些变化。约束，但文档非常差，它要么:

创建平面失败

BoolStatus = swDoc.Extension.SelectByID2("Right Plane", "PLANE", 0, 0, 0, False, 0, Nothing, swSelectOption_e.swSelectOptionDefault)
Set swLeftFace = swDoc.FeatureManager.InsertRefPlane(swRefPlaneReferenceConstraints_e.swRefPlaneReferenceConstraint_OptionFlip, distance, 0, 0, 0, 0)

或创建一个与第一个参考平面一致的正偏移平面。对于X=-1、X=0和X=1，会出现这种情况。

BoolStatus = swDoc.Extension.SelectByID2("Right Plane", "PLANE", 0, 0, 0, False, 0, Nothing, swSelectOption_e.swSelectOptionDefault)
Set swRightFace = swDoc.FeatureManager.InsertRefPlane(swRefPlaneReferenceConstraints_e.swRefPlaneReferenceConstraint_Distance, distance, 0, 0, 0, 0)
BoolStatus = swDoc.Extension.SelectByID2("Right Plane", "PLANE", 0, 0, 0, False, 0, Nothing, swSelectOption_e.swSelectOptionDefault)
Set swLeftFace = swDoc.FeatureManager.InsertRefPlane(swRefPlaneReferenceConstraints_e.swRefPlaneReferenceConstraint_Distance, distance, swRefPlaneReferenceConstraints_e.swRefPlaneReferenceConstraint_OptionFlip, X, 0, 0)

需要像这样添加选项:

Set swRightFace = swDoc.FeatureManager.InsertRefPlane(swRefPlaneReferenceConstraints_e.swRefPlaneReferenceConstraint_Distance + swRefPlaneReferenceConstraints_e.swRefPlaneReferenceConstraint_OptionFlip, distance, 0, 0, 0, 0)
