Joining/Combining Bodies

Anonymous — Sun, 19 Jun 2016 00:32:08 GMT

Hi! First of all, this is my first ever Fusion 360 model so I bear in mind that am a complete newbie.

As you can see in the screenshot below, I was designing a drone, and wanted to combine the main body and the ring part. I am not even sure if designing two bodies (main part and the ring) separately is a good idea. I have a feeling I might have to start this all over again.

My rough guess is, there might be a way to combine two sketches together in patch mode? Or I could design a fillet that links the disconnected part, but I really don't know. In short, I want to make a smooth connection between the main body and the ring part. Again, this is my first time using Fusion and I have no idea what I'm doing, so any help of suggestions will be appreciated!

Creating the ring and the main body is probably the only reasonable way to design this. If that's what you did originally then I can't clearly imagine how you got that little ramp with the ledge.

Regardless, take a few steps back till you have two completely separate bodies, and look at Create - Loft to combine them. After that Fillets should smooth things out.

This object could be perfectly fine designed using T-Splines.

It also exemplifies how a T-Spline can be combined with solid body features.
The main edges in the T-Slpline are creased and the radii are then applied as G2 solid modeling radii.

I've attached what I've come up with.

Edit:

Scratch that. Not true.

Learned lesson: Only open jabbers when looked at menu options in Fusion 360 😉

I have to say though that I started this in Blender. It's not that this cannot be done in Fusion - actually the solid body radius and other solid body modifications to a T-Spline can ONLY be done in Fusion - designing the control mesh is really much faster in Blender because I only have to work on 1/3, so basically one arm of the mesh. Something like the array modifier in Blender is sorely missing in Fusion 360.

Could not help myself 😉

If set up correctly, when creating this object with T-Splines the work on the control mesh cane reduced o 1/2 of one arm, so in essence 1/6 of the object.

The 1st half or the arm gets mirrored "Symmetry -> Mirror duplicate" and the result of that gets duplicated three times with "Symmetry -> Circular duplicate"
