[Windows] 智能房屋区域与家具布局器 V3
先上链接再聊其他https://wwart.lanzout.com/b01d71vhcj 密码:52pj客厅杂乱，于是我在上班摸鱼的时候做了这个工具，方便上班时多模拟摆放几次家具，
我本来想发布在原创，奈何AI写代码总版主不认，于是我在软件标题处增加论坛网址，发到精品软件总可以了吧
实测会报毒，但无毒！不需要联网！不需要登陆！无任何信息采集！
软件智能根据房间类型摆放家具，并非AI思考，而是根据家具摆放逻辑计算得出
功能是我使用不畅慢慢推敲逐渐增加的，目前已经满足我自身使用，留下python代码后不再更新
主要功能：
1. 手动或自动规划房间区域
2. 选中区域后直接修改位置和尺寸，拖动角点缩放
3. 重叠区域自动尝试挤到旁边
4. 增加、删除门窗，可设置所在墙、位置和宽度
5. 一键隐藏/显示全部家具
6. 选中家具后直接修改尺寸、位置和角度
7. 拖动家具时若与其他家具重叠，自动把其他家具挤开
8. 一键自动分散家具，尽量保证不重叠
9. 推荐家具尺寸根据所属区域自动缩放，并统一尝试放入
10. 家具带矢量俯视图标和连续旋转手柄
说明：
自动布局是启发式参考方案，不能替代建筑、消防、水电和施工设计。
