That feature still exists but we just implemented it in a much more robust way that doesn’t involve accidentally overwriting constructions that have the same name. All that you have to do is write the Construction object that you want to reuse over and over again to the following folder:
C:\Users\[USERNAME]\ladybug_tools\resources\standards\honeybee_standards\constructions
You can use the HB Dump Objects component to write the construction into that folder from Grasshopper.
The next time that you start Rhino/Grasshopper, that construction will appear in your library any you’ll be able to assign it to other Honeybee objects using the construction identifier instead of plugging int he construction object itself.
