斜角排列计算器 🔸
计算斜置拼布布局的侧边和角部设置三角形尺寸。获取精确的裁剪正方形大小和三角形数量，用于您的对角线拼布设计。
How to Use the On-Point Calculator
Enter the finished block size and grid dimensions (blocks across × blocks down). The calculator gives cut square sizes for both setting triangle types plus how many squares to cut.
Side setting triangles are X-cut (diagonally twice) to place the straight grain on the outer quilt edge. Corner setting triangles are cut once diagonally. Always cut setting triangle squares with the straight grain in mind.
Approximate finished dimensions are calculated before borders. Cut a few extra setting triangles as insurance — they use little fabric and prevent delays from cutting errors. Square up the quilt before adding borders.
常见问题
拼布中的斜置是什么意思？
斜置设置将拼块旋转45度，使其呈菱形排列。设置三角形填补边缘和角部的空缺，形成富有动感的视觉效果。
如何计算设置三角形的尺寸？
侧边三角形：将正方形裁剪至（拼块x1.414加3.2厘米），X形裁剪，每块4个三角形。角部三角形：将正方形裁剪至（拼块除以1.414加2.2厘米），单对角线裁剪，每块2个三角形。
为什么侧边三角形用X形裁剪而不是单对角线裁剪？
侧边三角形采用X形裁剪，是为了使拼布外边缘保持直布纹，防止拉伸变形。角部三角形同样采用单对角线裁剪，原因相同。
