做了一个免费的在线 Grid Maker,给画画/临摹用的 最近做了个小工具:[Art Grid Maker]( https://artgridmaker.com/) 主要是给画画、临摹的时候给参考图片加网格。上传图片后可以调整行列数、颜色、线宽、透明度等,然后导出 PNG / JPG / PDF 。 图片处理都在浏览器本地完成,不会上传服务器。 除了 Grid Maker ,还顺手做了一些绘画相关的小工具,比如比例计算、可打印网格、透视网格、Worksheet Maker 等。 目前还在持续完善中,欢迎大家体验,有任何建议或者发现 bug 都可以告诉我 🙏 [https://artgridmaker.com/]( https://artgridmaker.com/)

NASJI CAD: browser-based 2D drafting on a Mac — looking for file-compatibility feedback Disclosure: I’m part of the NASJI CAD team.
