I want to covert mesh body includes lattice to a solid body, haw can i do that?

Well whether it can be converted into a solid or not, that really depends on the complexity of the mesh, so you'll need to attach the mesh so we can take a look.

That being said, Fusion 360 doesn't handle mesh geometry that well, for example, there is a maximum limit of mesh faces acceptable for the mesh to be converted into a brep body, not to mention that if the mesh isn't fully closed, even if you were able to convert it to a brep body, it's not nessesserly going to be solid, so you might need extra work to do that.

The best workaround I always use is Rhino, whenever I have a mesh that is very complex for Fusion to handle, I use Rhino's Quad Remesh to convert it into a subd object, and then export it to Fusion as a quad mesh to convert it into a T-Spline body, which is one of the options that can be found in the convert dialog box in the sculpt workspace.

This workaround is really worth checking!

Volumetric Lattices created in Fusions cannot be directly converted into Solid Bodies.
Internally they are represented as voxels,. That representation is not accessible to users for output.

Theoretically you can convert it into a mesh, and then convert the mesh into a solid body with the organic version.

However, I've not been able to do this successfully.

You could also covert it using the default faceted option, but that creates very computationally heavy solids.

If that works, depends on the "complexity" of the mesh. I've used Blender's remesher, and InstantMeshes for this.

But with this "simple" gyroid cube created in Fusion as a volumetric lattice and then converted into a mesh in Fusion that is not very successful.

The resulting quad mesh has problems and cannot be converted into a T-Spline.
More experimentation is needed, but it is clear that this isn't a parametric or out-of-the-box workflow.
