C#根据数据画表并导出CAD 示例软件为Revit（其他软件原理也一样吧大概）
由于业务需求，需要从Revit视图中读取信息，并在视图上绘制一个表，并将该视图导出为CAD的dwg格式，由于刚学没多久，写的很烂，跟我一样的菜鸡看看就好，找找思路。
private void ExportToCad_Click(object sender, RoutedEventArgs e)

SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "CAD文件(.DWG)|*.dwg";

List<MaterialModel> mtd = this.materialdata;
try
{
ts.Start();
//过滤视图平面
List<Element> views = new FilteredElementCollector(document).OfClass(typeof(ViewFamilyType)).ToElements().ToList();
List<ViewFamilyType> needviews = new List<ViewFamilyType>();
needviews = views.Cast<ViewFamilyType>().Where(i => i.ViewFamily == ViewFamily.FloorPlan).ToList();
//准备画表的线集合
List<RevitLine> lines = new List<RevitLine>();
//存放每列最大长度的List
List<double> columnMax = new List<double>();
//用于接收每列最大值
int NameMax, LengthMax, PipeSectionMax, NotesMax;
//存放列头坐标的List
List<XYZ> headerLocation = new List<XYZ>();
//设置单元格宽度初始值
NameMax = 1;
int CountMax = 3;
LengthMax = 1;
PipeSectionMax = 1;
NotesMax = 4;
//XYZ[,] LocalTable= new XYZ[mtd.Count,5];
//遍历数组找最大
foreach (var m in mtd)
{
if (NameMax <= m.MaterailName.Length)
{
NameMax = m.MaterailName.Length;

//找完最大后 添加到保存最大的数组

columnMax.Add(CountMax / 1.5);
columnMax.Add(LengthMax / 2);
