MachineDolll Just to be sure, when you place the mouse cursor at the tip of a bone and press the Alt key (Option key on Mac) while dragging, you can change the length of the bone and move its child bones at the same time. When multiple bones are selected, you can change their lengths simultaneously, so even if the estimated size is slightly off, you can adjust it quickly and easily.
To clarify, I have attached a video demonstrating the expected workflow for creating curved bones:
I still find the idea of drawing a path to create bones interesting, but I'm still not sure if it's really faster.
If the goal is to eventually use path constraints to bind bones to paths, and if the feature automatically creates bones that match the length of the path when the path is created, that would be convenient, I think.
However, I'm not sure if drawing the path first in the usual bone creation process is really that good. Especially, I'm not confident that there would be a significant time difference between adjusting the angle of the path's knot handles to create a beautiful curve and rotating or resizing the bones to create the curve.
Additionally, even if you draw the path when creating the bones initially, if you later decide that you should have divided the bones more finely, you might end up adopting the workflow shown in the video above.
If you have any further thoughts or suggestions, I would appreciate hearing them.
