Short description of error
Have "align" setting in user preferences be set to "view". When adding new object, the object will have it's z towards the camera. If viewport is rotated and the addon settings are edited in the last operator panel, the object's rotation resets to view, which should not happen. Native blender objects retain their initial rotation without resetting on changing their settings, while all "add mesh" category objects reset their rotation, except bolt factory.
This rotation reset makes it impossible to see the effect changing many settings, mainly those affecting object height.
