Design options from linked models in host model

[Anonymous]

Can we recover the name of design options in a host model? This is the case when the revit modeller has not kept track of the chosen design options when he/she linked the revit models to the host model. I am trying to recover the names of the design options from the host model.

Thank you in advance.

Maybe you can filter for all BIM elements in the host model, read all their DESIGN_OPTION_PARAM or DESIGN_OPTION_ID values and create a list from that somehow.

All I know is that retrieving a list of the design options was tricky enough in Revit 2015 to render it almost impossible:

Q: Have a requirement to accept design options on the project.

A: Not exposed on the API, but just accept design option is easier, but needs to be on Revit Ideas.
