@Pilou: Thank you for the answer.

I tried FreeCAD but it's difficult to use, the interface is very confusing.

MoI is much simpler to use. Only needs some "Components" a la Sketchup, or dimension constraints.

I'm designing furniture, and a lot of elements are repeated tens or hundreds of times. If I need to make adjustments, its very time consuming to adjust every single element individually. In Sketchup, if I'm changing the parameters from one component, all the instances of the same component are updated automatically. Simple, but dead effective. Also the components from SK have some driven logic, so I can add some kind of parametrization.
