Snap to surface


I find the snap to surface feature great because you can select multiple objects, go in top vie, move one object and they all snap to the ground in their own local space.

However, it’s not working as well for me today… I’ve just placed loads of traffic lights in a scene and because the levels change, I selected all of them and moved one transform handle. Some moved to its surface but others are floating in the air or going under the ground.

After a few attempts it seems to work itself out but other times I have to select each one individually.

Any ideas?
