Arches: Semicircular, Not Pointed

A semicircular archway. The top of the opening is a perfect semicircle, with a radius equal to half the opening width, and the sides drop directly down to form vertical edges. The sides of the archway are also painted in a cream color, with a depth of over twenty centimeters, revealing the thickness of the wall, and the corners are also rounded. There are no door frames or moldings around the opening. All arches in a space use the same curvature.
Avoid: using pointed arches and horseshoe arches, making the arch a flat ellipse, adding moldings and veneers around the arch, having different arches use different curvatures.

一道半圓的門洞。開口的上方是一個完整的半圓,半徑等於開口寬度的一半,兩側直接落下成垂直邊;洞口的側面也是奶油色的塗料,深度超過二十公分因此看得出牆的厚度,轉角同樣抹圓。洞口沒有任何門框與線腳。一個空間裡的拱全部使用同一個弧度。避免:使用尖拱與馬蹄拱、把拱做成扁平的橢圓、在拱的周圍加線腳與貼皮、讓不同的拱使用不同的弧度。
