Help needed to clean up a sculpt form :)

[ianhughes7UFVF]

Hi

I am trying my hand at sculpting. I tried the attempt of creating a shoulder arrangement via other means but the sculpting seems to be the best option:

I have trouble finishing the form after thickening it so its 3mm thick inside as it comes up with errors.

I remembered that you need to go from the smooth option to the box option and tidy that up so there are no areas where parts overlap.

This is my box are of this. I have been trying to straigten out edges for it.

I remember there was an option to get lines all straight but cant remember how to do that, I also think the bottom area where everything gets in a jumble in the box view is my problem.

Is there advice out there how someone would sort this out.

Kind Regards

You need to provide the file, please.

I am convinced the inward thickening causes the self intersecting geometry.

If you remove that and it converts, that would be a good indication that thickening creates the problem.

Hi

Here is the fusion file for the sculpt if you would like to have a look at it to see what is stopping me from closing the form.

Its too large to add. Here is a share link:

When you thicken this inward, there is not enough space on the bottom of the object for 3mm of thickness. Additionally, the overall geometry is quite uneven.
I would recommend spending another hour or two to fine-tune the geometry.

If you compare this with yours, what do you observe?

Thickening with the T-Spline (form) operation would be the very last operation, as it isn't parametric and further modeling will be more difficult with the added geometry.

In the upper part, thickening works. In the lower part, it doesn't. So after thickening, you'll need to modify the vertices, similar to what is shown in the image:

In Fusion you'll have to do this vertex by vertex.

I used Blender's loop tools gstretch and curve to get the result in the image.

In retrospect It would have been quicker to model this from scratch.

A section view shows the result. Compare the top to the bottom:

Hopefully this provides you with some guidance.

Hi

The clean up you made of the bellows is absolutely ordered and clean. Very ordered in comparison to what I did.

That was what I was aiming for but was unable to achieve.

I also think that being more careful at the start on my part may have helped.

Cutting it down the middle like you did though I dont remember how to do to clean up the bottom area?

But I appreciate the direction.

Kind Regards

Hi

So looking at what you did, did you go inside and clean up the inner section at the bottom?

It looks to me that it was very ordered.

Also, how did you straighten up all the angles in the box selection of the bellows?

Kind Regards

Hi

I just realized that you said you created or cleaned it up in blender.

I havent used blender but it sounds as though its a very effect program.

Kind Regards

Vertex by vertex and edge by edge 😉
It is perfectly doable in Fusion, but with many years of experience in Blender, I find it quicker to do it there.
