When I enable other three snaps except snap to ground;penguinaz wrote:Did you try to:
1) disable Snap to Ground (the magnet with wavy line under)

On Free camera mode it refuses to draw.
On Top camera mode it draws but not on the ground but same crack occurs.
On 2, exact same thing happens on picture.
