This method really works for small parts(yet some of them are not small at all) like Probodobodyne OKTO, Probodobodyne HECS, Mk2 Lander Can, PPD-12 Cupola Module and so on. After removing all parts until the last, simply switch the type of the vessel to "DroppedPart" in the GUI and then the solo part will "glow" and it is able to move it as you like. However, parts like Mk1-3 Command Pod and
PPD-10 Hitchhiker Storage Container
are not able to move after performing the operations above.
All in all, if there existed a way to modify the root part in EVA Construction mod, we were able to move any parts(under certain permission) as we like.
I'm a native chinese speaker so it might be more precise and natrual to write in CN simplified: 这种方法对某些小部件(尽管有些看起来并不小)有用,比如探测动力OKTO, HECS, MK2着陆舱,穹顶舱。当我们把飞船拆到只剩这个零件时,在“航天器重命名”中把他们设为”残骸“,就可以移动了。然而,有些部件如MK1-3和成员贮存容器就不行,即使进行了以上操作。
这种逆天现象的根本原因是根部件设置有问题。只要能找到修改根部件的方法,所有问题都能迎刃而解。
