CONSTR#LINE 構造直線Horiz 水平Create a horizontal construction line.創建一個水平的構造直線Vert 豎直Create a vertical construction line.創建一個豎直的構造直線Crossed#Pair 相交對Create two construction lines which are perpendicular to each other.創建二條彼此垂直的構造直線Angle 角度Create a construction line at an angle.創建有夾角的構造直線Offset 偏移Create a construction line offset from another.偏移另一構造直線來創建構造直線。Pnt/Angle 點/角度Create a construction line through a point and at an angle to another entity.通過一點并和另一圖元成某一角度，創建構造直線。
