[实体对象] 通过闭合曲线生成面域

萧闫子 · 发表于 2014-1-8 16:40:14

前几天论坛QQ群里几位朋友想实现的问题，这里统一说下吧。通过闭合曲线生成面域的方法

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Geometry;
[assembly: CommandClass(typeof(BimCad.CreataProfile))]
namespace BimCad
{
class CreataProfile
{
[CommandMethod("LineToRegon")]
public void LineToRegon()
{
Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
Database db = doc.Database;
Editor ed = doc.Editor;
DBObjectCollection profile = Collection();
Region region = Region(profile);
ToModelSpace(region, db);
}
/// <summary>
/// 将一个实体添加到当前空间
/// </summary>
/// <param name="ent">对象</param>
/// <param name="db">数据库</param>
/// <returns></returns>
public static ObjectId ToModelSpace(Entity ent, Database db)
{
ObjectId id;
using (Transaction tr = db.TransactionManager.StartTransaction())
{
id = ((BlockTableRecord)tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite, false)).AppendEntity(ent);
tr.AddNewlyCreatedDBObject(ent, true);
tr.Commit();
}
return id;
}
/// <summary>
/// 选择集合
/// </summary>
/// <returns></returns>
public static DBObjectCollection Collection()
{
Database db = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database;
Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
Entity entity = null;
DBObjectCollection EntityCollection = new DBObjectCollection();
PromptSelectionResult ents = ed.GetSelection();
if (ents.Status == PromptStatus.OK)
{
using (Transaction transaction = db.TransactionManager.StartTransaction())
{
SelectionSet SS = ents.Value;
foreach (ObjectId id in SS.GetObjectIds())
{
entity = (Entity)transaction.GetObject(id, OpenMode.ForWrite, true);
if (entity != null)
EntityCollection.Add(entity);
}
transaction.Commit();
}
}
return EntityCollection;
}
/// <summary>
/// 由线条集合创建面域
/// </summary>
/// <param name="curveSegments"></param>
/// <returns></returns>
public static Region Region(DBObjectCollection curveSegments)
{
return Autodesk.AutoCAD.DatabaseServices.Region.CreateFromCurves(curveSegments)[0] as Region;
}
}
}
