Ground check in 3d environment

Unity Engine
1

Hi guys im using this method to do a ground check on a 2d demo i made and it works well.

public bool isGrounded()
    {
        RaycastHit2D raycast2D = Physics2D.BoxCast(playerStandingCollider.bounds.center, playerStandingCollider.bounds.size, 0f, Vector2.down, .1f, Ground);
        return raycast2D.collider != null;
    }

I’m trying to make something similar for a 3D model character, but when i remove 2D off everything, Ground gives me an error. Tried reading the documentation for RayCastHit but couldnt see how to structure it the same as the 2D version. Please help
