4.11 创建三维实体
使用Autodesk.AutoCAD.DatabaseServices.Solid3d创建三维实体 1）创建长方体
CreateBox(double lengthAlongX, double lengthAlongY, double lengthAlongZ) 该函数将会创建一个中心位于世界坐标系原点的长方体（默认） 2）平截头体(圆柱、圆锥、椭圆锥)
CreateFrustum(double height, double radiusAlongX, double radiusAlongY, double topRadius)
Height--表示平截头体的高度； radiusAlongX--表示底面在X轴方向的半径； radiusAlongY--表示底面在X轴方向的半径； topRadius—表示顶面半径，创建圆锥topRadius设置为0 3）创建金字塔
CreatePyramid(double height, int sides, double radius, double topRadius) 4）创建圆环体
CreateTorus(double majorRadius, double minorRadius) 5）创建长方体
CreateBox(double lengthAlongX, double lengthAlongY, double lengthAlongZ) 该函数将会创建一个中心位于世界坐标系原点的长方体（默认） 6）平截头体(圆柱、圆锥、椭圆锥)
