[求助]使用Arx 如何对AcadRegion进行旋转并取得体积?

ADZ168 · 发表于 2009-5-7 15:52:00

public double GetArea(AcadEntity[] entities)
      {
         object[] regions = (object[])aDocument.ModelSpace.AddRegion(entities);
         AcadRegion region = (AcadRegion)regions[0];
         double  reArea = region.Area;
         region.Delete();
         return reArea;
         AcadSolid sl = new AcadSolid();
      }
上面函数为Arx下使用面域求面积,现在想把面域旋转,求得面积和体积,应该用什么类?AcadSolid?Solid?Solid3d?如果能够帮忙说下,非常感谢,并请给出旋转函数,包括参数和返回值,并求体积?如果用第一个,则没有Revolve方法,如果后面两中,则又牵扯到Arx和com的区别了.

已做出,该用法如下
调用函数
AcadCircle cl=  op.CreateCircle(new double[] { 20, 20, 0 }, 10, "0", "ACAD_RED");
      AcadEntity[] ens = new AcadEntity[1];
      ens[0] = (AcadEntity)cl;
      double kk = op.GetVolume(ens, new double[3] { 0, 0, 0 }, new double[] { 1, 0, 0 }, 2 * Math.PI);
被调用函数,体积计算
  public double GetVolume(AcadEntity[] entities, double[] axisPoint, double[] axisDir, double Angle)
      {
         double dv = 0;
         object[] regions = (object[])aDocument.ModelSpace.AddRegion(entities);
         AcadRegion region = (AcadRegion)regions[0];
         Acad3DSolid sl = aDocument.ModelSpace.AddRevolvedSolid(region, axisPoint, axisDir, Angle);
         dv=sl.Volume;
         region.Delete();
         sl.Delete();
         return dv;
      }
