To add to the current DXF and DWG imports, I want to also request .3dm file imports and exports. For me, Rhinoceros has been much more consistent with the way it displays hatches (see the jagged hatch issue below) and it has many other features that make it my preferred choice over Autocad, which includes that it has a huge range of file types it supports for further exporting.
There are plenty of designers (ranging from naval, to architecture to industrial design) using Rhino and it would be nice to have native file support without the need to export from Rhino to import to Affinity.
