Modelling a solid

Nothing complex but I would like to replicate two similar solids to this two shapes in question (was using a .stl as a reference) and so far I have been unsuccessful in my attempts to replicate their curved shapes.

Edit: I would like to model similar ones, without using MeshEnabler so it's easier for me to work on them afterwards

Hi!

You can turn the mesh into solid...

Thanks, I assumed this is using MeshEnabler. I edited my post just now, I would like to learn how to model this solids from scratch since it's easier for me to work with them later and also to create new ones with similar shapes afterwards.

These kind of "organic" models are not an easy task and requires some advanced skills.

To create those solids, Your will need to use a lot of lofts, and sweeps (beyond the basics for some operations of course... extrude, revolve etc, ).

But... Usually, you can't get all the results you want with only solid operations for these kinds of geometry.

Often, You have to create independent surfaces, and finally obtain the "all solid" using that surfaces.

You have to know about 2D/3D sketch operations and surface creation/operations.

After you have the surfaces (which you can control with the sketches), you can use the STITCH tool, or SCULP tool to turn the surfaces into a solid.

Check also Freeform tools. I don't use it too much but can be a go-to if your job is mainly to work with that kind of geometry.

Here's an example:

Check the file attached.

As a bonus, you can open iLogig Form and control the geometry with the sliders

Hi! Another option is to use the Mesh Design environment in Fusion 360. It has quite a few mesh modeling tools to help smoothen the mesh and then convert it back to precise body geometry.

Many thanks!
