Doors not opening when the propforce function is used

[Your Computer]

Is there anyway to check this? Like on which axis it opens on and which direction?

In the level editor, when you select an object, you will see blue, red and green arrows. The blue one is Z axis, red one is X axis, green is Y axis. They point in relation to world coordinates.

BTW, you don't need more than 500 for prop force to open a door by force.
