Help with 'fanning out' shape

[t_smith5]

Hi

This is kinda a similar issue I had before, which I had help with here. I did try the same method, but was unable to. I couldn't get the shape to Intersect and show the needed purple line for some reason. 😕 Also, I'm not sure how effective or happy I'd be with that approach for this.

Essentially, I'm trying to get the sides to 'umbrella' outwards. So only the bottom protrudes outwards, but the top stays where it is. I'd love to be able to just move edges in Fusion... I've highlighted how the sides look in blue from these references of a toy:

Also, as a separate issue, the area I've highlighted in pink - what would be the best approach to achieve this? If you look at the first image from the front, there's like a crease/edge running through the middle of the shapes. They're essentially made up of three angled faces that have either been beveled or chamfered. I have the base shape added to my model, but I'm not sure how I'd approach that look using a Sketch or something. Maybe I'd need to extrude them out again and Taper...?

Anyway, back to the original issue - I've attached my file with the model's torso and the Sketch I've been using. I did try just extruding the shape out originally, but I'm not happy with how it looks from the top.

I'd still like to keep the top flat face so it lines up and is flush with the head. Much like it is on the toy reference. 🙂 As it is in the screenshot, you can see that the flat surface tapers...? So it's thin at the back and then becomes wider...? This is where I'd much prefer to move individual edges, so I could just pull the bottom one outwards and leave the top one where it is.

Thanks

I am travelling and can’t access the file for a while.

Sweep with Path and Guide Rail.  That front view - make the profile with those 2 straight lines.

Path is the curved torso, top edge for Path, bottom edge as Guide Rail.

Might help....

Thanks. I'll give that a look. Not tried those tools before, so hopefully I'll learn a new method. 🙂

Okay, kinda struggling to achieve this. You mentioned 'make the profile with those two straight lines', but which two lines do you mean? Looking at a video, the Profile needs to be a completed Sketch...? I used the Projection for that torso model to get the Profile. Also, it looks like you can only select one Path...? I selected the outer curved line of the torso, or torso Profile, though I would've thought that would need to be the Guide Rail...? Either way, pulling the blue arrow isn't doing anything so far.

Hi

Is there any chance you could elaborate on what you mean with this? I still haven't been able to get it work. 😅

Sorry I am still away from any Desktop, to make demos.

You outlined the side shape in blue.

disregard the top part of the torso, curve - it exists.

From there you have two straight lines.  The profile you want.

In a sketch that has those two lines.

Try this, go to Surface, 

Select Create > Sweep, in the top section, Select Path and Guide Rail from the drop down options.

Profile - Select those two straight lines.

Show the torso body.  

select the upper curve edge of the torso, where the top sketch line connects for the path.

Select the bottom curved edge for the Guide Rail.  You have some adjusting options, use full extents.

You are given a bevel angled curved body.  

You now see the shape is possible.  If you need a solid Sweep you then need to make these two line into a closed shape, surface shapes can be lines, but solid shapes need the blue shaded profile.

I'm afraid I'm still struggling to get this. I'm either failing to understand your explanation or it just isn't working for me. 😕

When you say: 'select the upper curve', do you mean this top horizontal line...? Though it's not exactly curved.

And likewise with the bottom curved line...?

Once all the options are selected, these are the arrows and placements I for them I get. That shape made of the two lines pokes through the side. It disappears whenever I try to take a screenshot though. And moving the arrows doesn't do anything.

I can only speak literally, to the second picture in message 1.

You don’t appear to be following that with your geometry, so there is a compromise to occur.

in the pic, the bottom black part of the torso, is much smaller, but that is the principle curve to use for the Sweep Path.  I was expecting a larger overhang with red and black barrels than you are making.  

So your Profile shape is as expected, but now nothing lines up to take that profile around the side of the torso.  If you realign the bottom of the profile to the black portion diameter, it won’t be the same as the Canvass you provided.  Smaller black dome, or smaller profile.

Hmm. I may have to skip this detail if there's no other way around it. At one point the size of both the torso and underside were made a bit too wide and I had to go back in the time-line and scale things back down so they match the reference images. They do that at the side nicely as they look like perfect spheres.

If I try to scale the underside so it's smaller, it no longer matches the silhouette/shape in the reference. I guess I'm a little torn as I'm mixing and matching elements from different designs and images and many show the torso and underside to be the same width.

That model looks to be the only interpretation where it fans out like an umbrella.

The original message pictures are different to these canvasses.  You told us that you were not sticking to much of anything.

I showed you the leg cuts from that line drawing in another thread, 3-4 weeks? ago,

but you said then - it was not suitable or what you needed.  (My words)

“My black body” was hollow at the time.

Might help.....

[t_smith5]

Well, there are some aspects of the designs I've wanted to implement, but others I've been experimenting with to see what works and looks best. But yeah, those leg cuts were something I thought I wanted to include, but in the end, I wasn't too happy with how they were looking. I decided to stick to how they're implemented from the figure, which is just a hole with a ball set in.
