工 务 局：

RetVal = object.AddExtrudedSolid(Profile, Height, TaperAngle)

对象

类型：块，模型空间，图纸空间

此方法适用的对象。

轮廓

访问：仅输入

类型：区域

配置文件只能是对象。Region

高度

访问：仅输入

类型：双

沿对象坐标系的Z轴的拉伸高度。如果输入正数，AutoCAD 将沿正Z轴拉伸对象。如果输入负数，AutoCAD 将沿负Z轴拉伸对象。

锥度角度

访问：仅输入

类型：双

挤压件的锥度角必须以弧度为单位。锥角的范围为 -90 至 +90 度。

正角从底座逐渐变细，负角逐渐变细。默认角度 0 表示垂直于其平面的 2D 对象拉伸。

返回值（RetVal）

类型：3DSolid

对象作为新创建的拉伸实体。3DSolid

言论

只能拉伸 2D 平面区域。

锥形拉伸只能用于在顶点处连续的循环。较大的锥度角或较长的挤压高度会导致物体或物体的某些部分在达到挤出高度之前与自身相交。当生成的实体与自身相交时，AutoCAD 不允许拉伸。
