I know I could create complex forms using for example Inkscape and extruding the 2D model in Gazebo, but in this way the Link Inspector is not able to compute automatically the mass given a certain density, neither the inertia matrix.

I thought I could create an elaborate model directly using Gazebo client adding bounding geometry and vision to a certain link. Anyway I was not able to find a way to implement the "subtraction" operation between geometries. Is it something actually feasible?

Can anyone help me please?

Thanks in advance for the help!

The model editor in gazebo is not a CAD software, you cannot do operation on geometries.

Use your preferred CAD to create your link geometry. These kinds of software usually have a functionality for computing inertias.

Alternatively, if you already have a mesh file in your hands, you can always use meshlab. There is a tutorial for that.
