I have the problem often, that a small mesh angle is need to avoid a visible tessellation on large light bended surfaces. This small angle cause a to dense mesh at all other parts. Since MoI is created for easy usage wouldn't not better to add a "max error" option (distance NURBS to mesh) first than adding a meshing single objects feature? Also, it's not seldom that a single part contain large light bended surfaces and small rounds. In this case the different parts can be separate meshed. Attached a very simple example. OK, "avoid smaller than" can be used, but ...

I know we talked about it in the past. Only I want keep it in the mind, maybe it can be implemented in v3. ;)
