When giving a thickness to a 3d mesh does not go the expected way

So the opening of your gh-file failed (sorry, aborted after 60 sec.), just had a look with disabled solver, somehow strange, why meshes? …, many duplicates in the .3dm… - however:
one technic (of many) to bring patterns onto geometry would be _flow wich works with surfaces. You would have to convert the polysrf with sections and _loft into a single srf.
There are many topics how such patterns can be constructed, e.g. this one by HS_Kim

So do not hesitate to study further :slight_smile:
