What's the name of the plugin/ extension that puts people on street level

What’s the name of the plugin/ extension that puts people on street level?
Or puts them on a plane. want to avoid hovering people.
Thanks!

Hello,
You can install jhs powerbar JHS POWERBAR | SketchUcation
That has drop at intersection and drop below functions

or ‘DropGC’ directly from the Extension Warehouse or @DanRathbun s ‘Move to Ground Plane’ …if it still works.

Both may require you to draw a bounding rectangle at the xy wold plane for having something to drop to.

Also Smart Drop.
