for now i made a script..
it reads all the sjon files from my offline Enscape Asset library and the elements in my library Revit file
With a different script i added a few parameters to my excisisting elements in my library Revit file..
i will adjust the planting family template so that these parameters will be in when i place new items.
%localappdata%\programs\Enscape\Data\RevitFamilies
i extract the Name, Category, Id, Tags and Revision from the sjon files
i am then comparing the Id's from the sjon files with the Id's from my project.
when i have Id's in my project that are not in the sjon files, then those elements will be turned Red
the sjon information is pushed to the parameters in the other elements
then in the script it gives me a list of the names of Assets not yet placed in the library Revit file
i also build in that it will compare the Revision number with the Revision of the elements in the library Revit file.
And it will turn those elements yellow so i know i need to update those.
this is a work flow that i can use until Enscape descides to push all info of the library Assets also into the Revit element.
