Relative keyframe in 3D

sometimes when annotating docid\ jw2jfj5i04upvcc7hv3ek , you need to annotate a box that has a fixed location with respect to another 3d box, such as a rider on a bike or a car on a trailer to make this easier, you can use the 'relative keyframe' feature drawing process find the 'best frame' for the two objects right click on the current object select the relative keyframe in the context menu select the other object that you wish to place the current object relative to the current object will be placed as it is to the selected object in the current frame in all keyframes additional usecases relative keyframe is one of the most important features for annotating stationary objects if the client data is of poor quality making stationary objects drift and the docid\ bcoytptdi72b6fmuqvntx blurry we need to annotate an object fully correcting for the drift, then for all nearby objects we can use relative keyframe to apply the same drift correction in all frames
