I found the issue. The reason is the following:\r\n - The RotorBlades have a parent component defined which is the rotor. If you remove it, it looks good.\r\n - If the rotor has a translation, the translation is duplicated as follows:\r\n   - The blade is built and already translated to its correct position\r\n   - Now! The blade is rotated around the rotors axis. This is where it starts to get wrong.\r\n   - In  the end, the blade is again translated with the rotors direction\r\n\r\nWhat we should do is:\r\n - Either build the blade first without the rotor translation\r\n - Or make sure the first translation is already included during the rotation"}}
