revit api创建图纸、图例、明细表

Revit API可以通过使用C#或VB.NET编程语言来创建图纸、图例和明细表。下面是一个简单的示例代码，展示如何创建一个新的图纸和添加一些基本的图形元素：

using Autodesk.Revit.DB;
using Autodesk.Revit.UI;
using Autodesk.Revit.Attributes;

[Transaction(TransactionMode.Manual)]
public class CreateSheetCommand : IExternalCommand
{
    public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
    {
        // Get the active document
        Document doc = commandData.Application.ActiveUIDocument.Document;

        // Create a new sheet
        ViewSheet sheet = ViewSheet.Create(doc, ElementId.InvalidElementId);

        // Set the sheet name and number
        sheet.SheetNumber = "A101";
        sheet.Name = "Ground Floor Plan";

        // Add a title block to the sheet
        FilteredElementCollector col = new FilteredElementCollector(doc);
        ElementId titleBlockId = col.OfClass(typeof(FamilySymbol)).OfCategory(BuiltInCategory.OST_TitleBlocks).FirstElementId();
        Viewport.Create(doc, sheet.Id, titleBlockId, XYZ.Zero);

        // Add a rectangle to the sheet
        XYZ p1 = new XYZ(0, 0, 0);
        XYZ p2 = new XYZ(10, 0, 0);
        XYZ p3 = new XYZ(10, 10, 0);
        XYZ p4 = new XYZ(0, 10, 0);
        Curve curve = Line.CreateBound(p1, p2);
        curve = Line.CreateBound(p2, p3);
        curve = Line.CreateBound(p3, p4);
        curve = Line.CreateBound(p4, p1);
        DetailCurve detailCurve = doc.Create.NewDetailCurve(sheet, curve);

        // Save the changes to the document
        doc.Regenerate();
        doc.Save();

        return Result.Succeeded;
    }
}

这个示例代码创建了一个新的图纸，设置了图纸的名称和编号，并向图纸上添加了一个标题块和一个矩形。你可以根据自己的需要修改这个代码，来创建图例和明细表。
