Is there a way to progressively scale an item along a plane or path?

Anonymous — Sun, 05 Aug 2018 00:40:13 GMT

Hi I have drawn up a piece of storm trooper shin "armour" It fits my slender son perfectly, me not so much, LOL. I think the bottom of it is about the right dimension to fit, but at the top I need to scale X and Y up 5% (or some figure) So at the bottom 0% up scale progressing to (say) 5% at the top of the model. Is there any way to do this?

No...

But vote for this! I've been asking for a long time...

It's already in the Sculpt workspace- why not create a body shaped like... uh... your body (heh!) to conform the armor to?

@I_Forge_KC yes, that would really be nice. Voted for!

@Anonymous The base shape seems to be a T-Spllne. You can use a gradual scale, even non uniformly across the three axis when enabling soft modification in the edit UI.

If you can share your model I'll show you how.

I usually do that stuff in Blender.

I don't know if you feel that creating your desired shape in the Model environment, with Capture Design History turned on, is desirable.

If you would be okay with it, then I propose a series of "section" profiles that could easily be adjusted on the fly. I didn't go so far in my example to constrain and dimension any of the splines, but you certainly could do that if you know measurements around your leg at various points.

Because it needs to be changeable per person. So anyone can take this "standard" model/drawing and re-scale the parts to suit their body chape.

Sorry been snowed under with work and life just getting back to this.

All my work is GPL so the source files are on thingiverse. In this model's case its here,

Was hoping for something not involving re-drawing as that would be a huge effort every time, but thanks anyway.

I'd like to see that, Peter- I've attached his design. It's a bit cluttered, so identifying parts to confront might prove prohibitive.

To the Original Poster, you'll improve your chances of receiving the gift of time and expertise by Attaching your design directly to your post- and not requiring would-be-helpers to go on a scavenger hunt.

This is an aspect of Fusion that requires the most forethought- realizing designs in a way that allow parametrics to be exploited. The only path to that level of design, I reckon, is a lot of work- either through accumulated experience solving problems with this tool, or a concerted effort to develop the capacity in a design. Examining your design, I can see where adapting to the scheme Chris suggested might be daunting- but in the long run, a worthy exercise. Relatively "free" modelling of rescaled parts doesn't come free- the time savings are front loaded with time investment.

How did you get into this mode?

The first half of the video is Fusion in default mode, click and drag articles in the window, is default, while sketches are under constrained.

second half was Edit sketch, to redefine spline handles.

Might help...

It isn't a "mode." That's the default behavior of sketches that are visible in the workspace. The key to being able to drag stuff around is that it not be constrained within the sketch. If an item is free to be dragged around while you are in Edit Sketch mode, it will be free to drag around outside of the Edit Sketch mode also.

OK, will have another go, not really following well. By the way this was scaled to my son so for him its great, my wife and I not so much......
