This tool inserts objects perpendicular to the surface with the disposition known in jewellery as "pavé".

It can be used on simple surfaces, with 4 well-defined edges. More complex surfaces and spherical forms will, most likely, produce unwanted effects. Given that our pave disposition is usually guided by aesthetical and not mathematical considerations, this tool will be used mainly for fast and approximate account of stones to be used in the project, and therefore the overall cost of the needed materials, before the actual stone insertion. .
