半圆形门窗的测量：测量出半圆形洞口的直径或半径和圆弧最远点到可确认定位线的垂直距离。

Measurement of semicircular doors and windows: measuring the diameter or radius of a semi-circular opening and the vertical distance from the farthest point of the arc to the confirmation location line.

圆形门窗的测量：测量出圆形洞口的直径或半径。

Measurement of circular doors and windows: measure the diameter or radius of the round hole.

弧形门窗的测量：测量出弧形洞口上至少三个特殊点（可确认定位点）到可确认定位线的垂直距离。

Measurement of arc doors and windows: measure the vertical distance of at least three special points on the arc hole (the confirmation point) to the confirmation location line.

直边形门窗（各边均为直线形式）的测量：测量洞口上所有边拐点到可确认定位线的垂直距离，也可以采用长度（或宽度）与角度混合使用的方式，但所列数据要详细，确保其尺寸唯一性。

The measurement of a straight side door and window (all sides in a straight line): measuring the vertical distance of all side inflection points on the hole to the identifiable location line and the way of mixing the length (or width) with the angle, but the data in detail should be detailed to ensure the uniqueness of the size.

对于洞口侧面为斜面（即洞口相对两侧面不平行），应在向用户了解门窗安装时在洞口内进深量，并测量相应安装部位尺寸。

For the side of the hole, the side of the hole is not parallel to the two sides of the hole. The depth of the hole in the hole should be understood to the user when the door and window are installed, and the size of the corresponding installation position should be measured.

复杂异形洞口的测量可根据实际情况或需要做洞口样板。

The measurement of complex special-shaped openings can be made according to actual conditions or needs.

异形窗尺寸测量方法见附图四。

The method of measuring the size of the special-shaped window is shown in Figure four.
