Strengthen the collision decision area of planet studio's stucture components

1,Sometimes when you put two or more stucture components (especially cube cylinder) together and have some overlaps,
the ability of collision decision seems to be failed--droonauts,crafts will drop through the overlaps to the ground or into the water.
2,When you put some cylinders rotated at an angle, the ability of collision decision seems to has an error--looks like the
collision decision box has been expansided larger--not just on the surface of the sturcture it self--droonauts can walk in the
air and crafts will crashed on or stuck in the air wall.
