How to make a bone ?

[Blue_Wings]

Hi guys,

Really need your help. I am trying to model mammal bones (manatee fingers) for a science project. I am new in Fusion and I'm used to making things that are straight or circular not organic.

I have sketched the profiles in multiple planes but couldn't make anything close to a what I need. I tried extruding, revolving, lofting, sweeping and none of it worked. Also tried the Form environment for few days and my results ranged from weird to scary.

Is there a way to do it without the Form environment ?

I am attaching the Fusion file and a photo of what I am trying to recreate (my sketches are not based on this photo and i'm only including it to give you an idea how the end result should look like)

Thanks and Happy holidays !!

Trying to do this with Loft or Sweep is going to be very tedious.  You can probably do it, but each digit of each finger is going to require a lot of fooling around - many sketches, profiles, rail curves, etc.  Form is definitely the environment for this kind of organic modeling.  Why do you not want to use Form (T-Splines) for this?

I would not do this without the Form environment!
But if some form of parametricity would be needed I'd do this in Blender, for example with shape keys. This is functionality specific to an animation software that would make little sense in Fusion 360 except for very rare cases such as this.
Another way to get stuff to stretch in Blender is animation bones.
