// 【关键修改点】无圆头模式：不需要绘制大圆弧外轮廓，或者绘制一个直角的轮廓。
// 由于 DrawBoxSideFrame 已经绘制了左右两侧的边框线（含圆角），
// DrawBoxSectionContourWithFillet 绘制了中间。
// 它们的合集就是外轮廓。
// 原代码 DrawBlockRoundHeadOutline 是为了画那个额外的“耳朵”圆弧。
// 这里我们只需要一个简单的矩形外框作为“外轮廓实体”（如果需要）
// 或者就像原逻辑一样，如果没有大圆弧，就不画 DrawBlockRoundHeadOutline。
// 但用户要求“包含尺寸标注和参数标注线都复制过来”，且标注依赖于这些几何位置。
// 这里我们跳过 DrawBlockRoundHeadOutline，因为那是特定的圆头形状。
// 如果用户想要最外侧也是封闭的线，SideFrames + SectionContour 其实不完全封闭（中间有重叠线）。
// 让我们看看原逻辑：DrawBlockRoundHeadOutline 是独立的一圈粗线。
// 此处我们是否需要一个“无圆头”的外圈粗线？
// 我们可以仅依靠内部组件，或者画一个大的圆角矩形包围所有。
// 鉴于 SideFrame 已经画了外侧线，我们这里可能不需要额外的 Outline，
// UNLESS the user implies "No Round Head" means "Rectangular Head".
// Let's assume the Side Frames define the shape.

// 左侧框线 DrawBoxSideFrame(..., xInnerLeft, xSectionLeft, ...) 是左边的部分
// 右侧框线 DrawBoxSideFrame(..., xSectionRight, xInnerRight, ...) 是右边的部分
//
// 问题在于：当 SideFrame 的 filletR=0 时，它画的是纯直线矩形。
// 而中间的 DrawBoxSectionContourWithFillet 依然可能有 innerFilletR > 0，导致它的角是圆的。
// 当两个矩形拼接时，如果中间那个有圆角，而旁边的是直角，交界处的高度看起来是一样的（yBottom, yTop），理论上应该重合。
// 但如果中间框的圆角导致其垂直边缩短（圆角起止点变化），而SideFrame只是简单的画到 yTop/yBottom，
// 它们在垂直方向上是重合的。
//
// 观察截图，缝隙似乎出现在连接处。
// 中间框 DrawBoxSectionContourWithFillet 在 xLeft, xRight 处的垂直线段是：
// 左侧: (xLeft, yBottom+r) 到 (xLeft, yTop-r)
// 右侧: (xRight, yBottom+r) 到 (xRight, yTop-r)
//
// SideFrame (以左侧为例, isLeft=true, filletR=0):
// xEnd 是连接点 (即 xLeft)。
// 它画的线包含 (xEnd, yTop) -> (xEnd, yBottom)
//
// 理论上 (xEnd, yBottom) 和 (xSectionLeft, yBottom+r) 之间有高度差 r，但这部分重叠区域应该由圆弧填补？
// 不，DrawBoxSectionContourWithFillet 画了完整的闭合回路，包括圆角。
// SideFrame 画了另一侧。
// 只要 SideFrame 的垂直边完整覆盖 (yBottom 到 yTop)，就不应该有空隙，除非 SideFrame 的 x 坐标没对上。
//
// 另一种可能是：DrawBoxSectionContourWithFillet 的圆角不仅影响y，也影响x？不，圆角是在角内切的。
//
// 让我们仔细看 DrawBoxSectionContourWithFillet 的左边线：
// Vertex 6: (xLeft, yTop - r)
// Vertex 7: (xLeft, yBottom + r)
// 这两点之间是直线。
// 下方圆角从 (xLeft, yBottom+r) 到 (xLeft+r, yBottom)。
// 这意味着在 xLeft 这一条垂直线上，只有 yBottom+r 到 yTop-r 这一段是有线的。
// yBottom 到 yBottom+r 这一段是空的（因为线往右弯去画圆角了）。
//
// 而 SideFrame (isLeft=true, filletR=0) 在 xEnd (即 xLeft) 处的线是：
// Vertex 0: (xEnd, yBottom)
// Vertex ... (最终回到 xEnd, yTop)
// 如果 SideFrame 是开放的 (Closed=false)，我们来看看它的路径。
// isLeft=true:
// P0: (xEnd, yBottom)
// ... 画左边的框 ...
// P4: (xEnd, yTop)
// 它画了两条水平线回到 center，但是没有画连接这两个点的垂直线！
// 原逻辑可能是依赖中间框来画这条线？
// 是的，FeatureDrivenDrawer 里的逻辑通常是一块块拼接，共用边如果不画两遍的话。
//
// 修正方案：
// 无论中间框是否有圆角，SideFrame 作为“框线”，应该把与中间框接触的那条边补上，或者延伸进去。
// 既然中间框是有圆角的，那么在角的地方，中间框的线是缩进去的。
// SideFrame 必须画出完整的一条垂直线 (xEnd, yBottom) 到 (xEnd, yTop) 来“封口”，
// 虽然这会导致与中间框的直线部分重叠，但能盖住圆角留下的空隙。
//
// 当前代码 isLeft=true 时：
// poly.AddVertexAt(0, new Point2d(xEnd, yBottom), 0, 0, 0);
// ... (往左画) ...
// poly.AddVertexAt(5, new Point2d(xEnd, yTop), 0, 0, 0);
// 确实是开口的“C”形。
//
// 我们需要让它闭合，或者至少画上那条连接线。
// 直接将 poly.Closed 设为 true 即可！
// 这样 (xEnd, yTop) 会自动连回 (xEnd, yBottom)，形成一个完整的矩形框。
// 这样右边那条垂直线就会被画出来，填补中间框圆角留下的上下空缺。

// Property type for color override is usually Autodesk.AutoCAD.Colors.Color
// But specifically for Dimclrd/e/t properties on the object wrapper, they might be exposed as Color objects.
// However, standard COM/ActiveX way involves variables. In .NET API, we usually set Dim Variables on the Database or style.
// BUT, effectively, we can set overrides on the Dimension entity itself if it supports the property via reflection
// typically mirroring the system variable names.
// Let's rely on the property reflection if available, but for color, it's tricky.
// The most robust way using .NET API for dimension overrides is strictly through the properties if exposed,
// OR modifying the XData/Dxf codes.
//
// WAIT. FeatureDrivenDrawer uses TrySetDimProp with reflection. Let's replicate that simple logic.
// Note: Dimension class properties in .NET don't map 1:1 to DIM vars (e.g. Dimclrd is not a property of Dimension).
// They are properties of DimensionStyle. To override on an instance, we strictly need to simple properties if they exist?
// Actually, the previous code used reflection on 'dim' object.
// Let's double check if "Dimclrd" exists on RotatedDimension. It usually doesn't.
// It holds "DimColor" maybe? No.
//
// Re-reading FeatureDrivenDrawer.TrySetDimProp ...
// It sets properties via reflection.
// Let's implement a safer version: using dynamic if possible, or just standard properties.
// Actually, correct way to override dim var on an entity is NOT via properties (they don't exist),
// but by creating a DimStyle override or setting specific properties like DimensionText.
// HOWEVER, RotatedDimension DOES have properties like 'Dimclrd' EXPOSED dynamically in some contexts?
// No, standard .NET API does not expose 'Dimclrd' as a property on RotatedDimension.
//
// Wait, FeatureDrivenDrawer code shown in Step 182 DOES NOT show TrySetDimProp setting 'Dimclrd'.
// Step 200 shows TryApplyDimSizeOverrides calling TrySetDimProp(dim, "Dimclrd", 3).
// This implies that at runtime, the Dimension object (or a wrapper) HAS these properties?
// OR, the User's environment has an extension method?
// OR, FeatureDrivenDrawer.TrySetDimProp handles it magic?
// Let's look at FeatureDrivenDrawer.TrySetDimProp in Step 182.
// It does `obj.GetType().GetProperty(propName)`.
// If this works, then RotatedDimension must have these properties.
// Let's assume they exist as per the working example in FeatureDrivenDrawer.
