vgeorgiou , I'm afraid, ArchiVision models are not yet officially supported by Enscape for SketchUp. Support for them is generally filed as a feature request on our agenda so I gave the topic a further upvote through your voice.
Also, we have another topic on our agenda to allow you to import your own models into the asset library. Maybe this would be of interest to you? If so, I'll happily give the topic a upvote through your voice as well, just get back to me.
Grateful for your response and upvote.
It probably would be of interest, it thats in the pipeline. Though thinking of our workflow, as we are converting objects through Archvision for Revit it would be good to have to avoid doing this again through Simlab or something similar for Sketchup aswell. The Archvision tool being available for both programs is hugely beneficial and an efficient use of time for us when working between the two programs and that inter-connectivity is so crucial if we are using Enscape for both.
So if both can be done together and released as an upgraded feature, then great.
