C4D地面吸附对齐插件 Snap To Floor 1.3 for Cinema 4D  R15-R20 Win/MacSnap To Floor可以让物体快速吸附对齐到Y轴地面，同时可以对物体做旋转等Snap To Floor is similar to the drop to floor plugin here on the site except that it’s live! You can rotate your object in the scene and your model will always keep its lowest point on the Y axis. This makes animating things like animating any rolling objects a breeze!
