Bath Modelling: Seeking Strategy/Workflow Solution

Anonymous — Wed, 12 Dec 2018 11:29:45 GMT

Hello all,

My employer has graciously allowed me the opportunity to learn Fusion on the job, but I have reached a bit of a hurdle trying to find a strategy modelling these bath tubs. I am okay with lofting, creating sketches and rails and so on, shelling out the bath, but when it comes to creating the 'roll top' part of the bath to create that rim (see attached reference), I can't really think of a way round it.

I assume the strategy would be to take that top loop and extrude the entire loop outwards along a curved profile so it spills over and down toward the floor. But how...?

I've been through the whole tutorial series, but a pointer here I think would give me a nice shove in the right direction after hitting quite a few dead ends.

Thanks!

What is the purpose of modeling these ?

Models for visual representation and for manufacturing are often modeled differently, thus the question.

Hello Peter,

It's not for manufacturing purposes, simply for representation & visualization purposes, though I am working off real-world products, so being able to maintain and be sure of specific dimensions is somewhat important.

Using sweep in the patch environment gives you a simple way to do a simple form.

If you want a more defined lip you might want to use the loft feature in the patch environment.

I'd second what @lichtzeichenanlage posted.

Another way to model this is to use T-Splines. Most archviz models are created using Sub-D modeling, not CAD.

Thank you for your input, it has been really useful to deconstruct your process in the timeline.

May I ask what your approach would be, say if the nose of the bath sweeps upward at one end at the nose? (see attached) I still need to brush up on my skills before attempting this, but interested what the process would be. Would you simply add more intermediate profiles for the bath rim shape, at different heights, or would it be a separate operation after the basic shape had been swept/lofted out?

@TrippyLighting I'm a little more familiar with sub-d modelling coming from a Cinema 4D background, but by no means proficient. So far in Fusion I've been able to bake out some okay-ish meshes for what we intend on doing, but I may end up switching back if the texturing becomes too torturous.

Fusion 360 does not allow UV unwrapping but otherwise can produce pretty nice renderings.

It lacks the control of light sources you'l find in more mature render engines.

Lip with one diameter = sweep

Lip with changing diameter = loft

Ah, I now understand fully. Thank you, again.
