Editing Streamed Rhino Blocks in Blender

This is a really good question, one that others have asked, and are likely to ask again, so I thought it deserves a complete response. As a bit of background. Rhino/AutoCAD blocks, Revit families, Sketchup components, Unity prefabs etc, all represent instancing of a group of many objects. Blender’s equivalent to this is Instanced Collections. These are maybe not the most common form of instancing in Blender, however, they are a pretty close analogue of Rhino Blocks and the other types of …

Tl;dr Speckle instances (be it revit families or rhino/autocad blocks) will be received as collection instances in blender. These are special type of empty that instances a entire collection of objects, as such are a close match to the same concept in Speckle and other 3d apps.

These aren’t the easiest to edit inside blender, so i recommend you checkout the receive option to receive Speckle instances as linked duplicates, which behave more like standard blender objects.
