[求助]使用Arx 如何对AcadRegion进行旋转并取得体积?

ADZ168

 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;
        }
