revit二次开发API示例 创建幕墙并操作其幕墙网格
1.2k
2024/11/24
应用程序名称：CurtainWallGrid
Revit 平台：所有
Revit 版本：2011.0
首次发布于：2009.0
编程语言：C#
技能级别：中等
类别：元素
类型：外部命令
主题：创建幕墙并操作其幕墙网格。
概要：
本示例演示了五个主要功能：
1. 如何根据特定的层数和墙体类型创建幕墙。
2. 如何检索幕墙的幕墙网格信息。
3. 如何编辑幕墙网格的数据。
4. 如何检索幕墙网格的网格线。
5. 如何编辑幕墙网格的网格线和格栅横梃。
项目文件：
Command.cs
该文件包含了“Command”类，该类继承自“IExternalCommand”接口，实现了“Execute”方法。
MyDocument.cs
该文件包含了“MyDocument”类，用于管理本示例中使用的所有数据。
WallGeometry.cs
包含了一个名为“WallGeometry”的类，用于管理幕墙数据。它可以创建新的幕墙，并获取幕墙的数据。
WallDrawing.cs
包含了一个名为“WallDrawing”的类，用于在画布上指定幕墙的基线。
GridGeometry.cs
包含了一个名为“GridGeometry”的类，用于管理幕墙中的幕墙网格和幕墙网格线信息。它可以检索幕墙网格和幕墙网格线的数据；也可以编辑它们的数据。
GridDrawing.cs
包含了一个名为“GridDrawing”的类，用于管理画布上幕墙网格和幕墙网格线的2D视图。
GridCoordinates.cs
包含了一个名为“GridCoordinates”的类，用于管理幕墙网格在3D和2D格式之间的变换矩阵。
MathTools.cs
包含了一个名为“MathTools”的类，用于管理变换中使用的数学类。
功能：
- 创建指定层和墙类型的幕墙。
- 检索幕墙的幕布网格。
- 检索所有幕布网格的属性。
- 检索幕布网格线并编辑它们：添加新的网格线，锁定/解锁网格线，移动网格线，添加/删除段，添加所有段。（注意：它模仿部分UI操作，如面板自动合并功能等，但仅支持简单情况。如果对幕布网格进行复杂操作，样本的外观可能与UI不同。）
- 检索所有附加的柱子并操纵它们：将柱子添加到幕布网格段中并删除幕布网格的柱子。（注意：由于Mullion类的限制，只允许将柱子添加到网格线的段中，不能将柱子添加到幕布网格的边缘。）
实现：
- 使用元素过滤器获取活动文档中的所有视图。
- 使用适当的幕墙类型通过Autodesk.Revit.Creation.Document.NewWall(Curve curve, WallType wallType, Level level, double height, double offset, bool flip, bool structural)方法创建幕墙。
- 通过CurtainGridLine AddGridLine(bool isConstVisUGridLine, Revit.Geometry.XYZ position,bool oneSegmentOnly)添加幕布网格线。
- 通过bool Move (Revit.Geometry.XYZ moveVec)移动幕布网格线。
- 通过void AddSegment(Revit.Geometry.Curve^ curve)添加一个段。
- 通过void RemoveSegment(Revit.Geometry.Curve^ curve)移除一个段。
- 通过ElementSet AddMullions(Curve segmentCurve, MullionType mullionType,bool oneSegmentOnly)添加一个柱子。
指南：
1. 打开Revit Architecture 2009并创建一个新文档。
2. 运行此命令。
3. 弹出一个“Curtain Wall”对话框，其中有2个选项卡，第一个是“Create Curtain Wall”，另一个是“Curtain Grid”，此时仅限于第一个选项卡。
4. 所有视图和墙型在两个下拉列表中列出，通过从列表中选择一个来指定它们，指定的视图和墙型将用于幕墙的创建。
5. 幕墙创建需要一个基准线。左键单击画布左侧以指定基准线。在绘制基准线时按“ESC”键停止绘制基准线。单击“清除基准线”按钮以重新绘制基准线，单击“创建幕墙”按钮以使用指定的基准线、视图和墙型创建幕墙。完成后，可以切换到“Curtain Grid”选项卡页。
6. 幕布网格的所有属性都列在右侧的属性网格中。
7. 幕墙的幕布网格在左侧的画布上绘制出来。
8. 所有支持的幕布网格和幕布网格线操作：添加水平网格线、添加竖直网格线、锁定或解锁网格线、移动网格线、添加段、删除段和添加所有段
9. 所有幕布网格和幕布网格线的操作都限制在幕布网格的边界内，这意味着鼠标指针必须移动到边界内，操作才能正常工作。
10. 连续操作：默认情况下，在一次操作完成后，操作将停止并改为“等待”。例如：在绘制一条水平网格线后，用户应该从组合框中指定另一个操作。如果用户想一次性绘制多条水平网格线，他/她应该按下“Ctrl”键并保持连续操作。例如：从下拉列表中选择“添加水平网格线”，按下“Ctrl”键，在画布上绘制一条水平线，之后用户可以在没有再次指定操作的情况下绘制另一条水平线。如果用户想停止连续操作，他/她可以释放“Ctrl”键并执行最后一个操作，在最后一个操作完成后，操作将停止并改为“等待”；他/她也可以按“ESC”键强制停止当前操作，并将操作改为“等待”。
11. 对于“添加水平网格线”，将鼠标移动到幕布网格区域内，将显示一条虚线水平网格线，它是即将添加的新水平网格线，单击左键将其添加到幕布网格中。不允许添加一个网格线重叠另一个网格线。支持Ctrl键和ESC键。
12. 对于“添加竖直网格线”，与“添加水平网格线”类似，只是虚线是竖直的。支持Ctrl键和ESC键。
13. 对于“锁定或解锁网格线”，将鼠标指针移动到网格线上悬停，网格线的锁定状态将显示为“已锁定”或“未锁定”提示，单击左键切换锁定状态，提示将更新。
14. 对于“移动网格线”，仅允许移动未锁定的网格线，因此在移动网格线之前确保网格线未锁定。单击未锁定的网格线来决定要移动哪条网格线，然后移动鼠标来决定将网格线移动到哪个位置。再次单击左键完成移动网格线。支持Ctrl键和ESC键。
15. 对于“添加段”，只允许在先前删除段的地方添加段，因此默认情况下无法执行“添加段”操作，因为还没有删除段。首先删除一些段，然后使用此操作将它们添加回去。支持Ctrl键和ESC键。
16. 对于“删除段”，一条段不允许被删除两次，这意味着我们只能删除之前没有删除的段。支持Ctrl键和ESC键。
17. 删除一个段可能会导致其他“共线-悬挂”段自动被删除。例如，在图1中，删除“段A”（水平的、红色高亮显示的段）将使“段B”（水平的、棕色的）自动被删除，因为“段B”是一条“共线-悬挂”段。
18.在“删除分段”功能和“自动删除”功能中，不允许删除窗帘网格线的最后一个分段。例如，在图2中，由于“分段B”是窗帘网格线的最后一个分段，所以不允许删除它。 在图3中，删除“分段A”将导致“分段B”成为“共线悬挂”，并尝试删除“分段B”，但是由于“分段C”已经被删除，所以“分段B”将成为其窗帘网格线的最后一个分段，所以不允许删除“分段A”。因此，也适用于“自动删除”功能。
19.在“删除分段”功能中，删除一个分段可能会自动隐藏其他“交叉悬挂”的分段。例如，在图4中，删除“分段A”会使“分段B”成为“交叉悬挂”，因此“分段B”将被标记为灰色，表明它被自动隐藏了（图5），就像Revit UI一样（在界面上，它是不可见的，只有在鼠标悬停时才会显示）。
20. “添加整个网格线的分段”功能类似于“添加分段”，只允许将此操作应用于已删除分段的网格线。支持Ctrl键和ESC键。
21. “添加所有分段的框条”功能将在窗帘网格的所有可见分段上添加框条。（注意：由于Mullion类的限制，无法在窗帘网格的边缘添加框条。）
22. “删除所有框条”功能将删除窗帘网格中的所有框条。
23. 单击任一选项卡页面中的“退出”按钮将关闭对话框。
