Help with Sculpting from 2D Sketch
Hi George,
That's a pretty cute design! I like it.
Regarding recommendations, I think that what you've done here so far is pretty good. It's actually pretty clever the way you've used Move as a way to subtract the same sphere from multiple locations - that way you don't have to create multiple spheres. It's almost like a manufacturing operation.
I did notice a couple of things you could optimize in this design. One general suggestion is to edit features, rather than add subsequent scale or Press/Pull features when you can. For instance, your initial sketch and extrude. You drew a small sketch, then extruded it, then used Press/Pull and scale. All of those operations are perfectly valid, just not really necessary. You can always go back and edit features to make them the right size, then you won't have to do a bunch of scale features or offsets. So, you could have edited the original sketch and created curves in the larger size. Similarly, when you create the sphere, you subsequently have a Scale feature to make it bigger. You can just edit the original sphere feature to make it the right size. I also noticed that there was one unnecessary Form feature in the middle of your design, which you can just delete.
I cleaned up your design a big and attached it, just to give you an idea of another way to look at it:
I hope you continue to use and enjoy Fusion, and don't hesitate to ask questions here!

Hi @george,
If you want to model the crease lines, I think you would have to start over, and use a Form feature for the whole thing. I tried a bit, but my Sculpt modeling skills are not up to the task. Perhaps @donsmac, or @TrippyLighting could give it a shot. There are probably several ways to attack this, from creating Faces for the basic shape, and using Thicken to add thickness, or starting with a primitve like box, and just squishing it into shape. A general trick for doing something like the crease lines is to use the Crease command. This does pretty much what it says, allows you to put a sharp crease into your model. You would want those to line up with the creases in the tie.
I would not recommend trying to lay this out as a ribbon and fold it up. You could probably do this, but it would get messy :).
And, unfortunately, today there is no way to show the scale in the UI, as you suggest. You can use the Measure command to measure things, and in your Canvas, use Calibrate to get it to the right size.

I submitted a response earilier but for some reason it did not appear in the forum. Maybe it will show up later?
Here's what I came up with:
There's still a problem with the seem showing across the bow, but with some further tweeking of T-spline points to get the surfaces closer to being even, then cutting out a piece that contains the visible seem and using a loft to fill the space back in with tangency, might work? I will see if I can get that to work.
Here's a screencast showing the the process from the beginning, it's about 48 minutes long.

Thanks, @donsmac! I really like this technique of yours. I tried, yesterday to figure out how to apply that here, but I struggled...

Hi George, I did try to remove the visible seem using several methods that were not successful, that included cutting out a retangular chunk and trying to fill it in with either a solid loft or a patch for the hole. The patch did not give tangency to the surface and the loft still gave some kind of seem. Adding a varible fillet gave the best results but not perfect:
I've attached the model. Good luck. One other thing. The partial dot on the bow (I missed that one on the video) was made by making a full dot and adding the piece that covers part of it afterwards.
