I can’t tell for certain, but the second example does not look like something that was surface modeled in 3D, rather the main form was surfaced and a textured piece of sheet metal was formed around it. That could easily be faked using a displacement map on top of an existing surface, but to actually model that in Solidworks is probably close to impossible (or so time consuming it would never work for an actual workflow).
For the tessellated patterns, if you view the polygons as planes that have been trimmed back into a 3 sided surface, you can see how they can be made by revolving around a center point and then merged back together.
