The WV2019 export plugin should be available soon, unfortunately the separate layer has not been added by the developers...
They might include it in the next release.
I do not understand, you advertise on your website that its compatible with Vectorworks! How is it you are unsure how or when exporters will be fully supported between Vectorworks and Artlantis 7?
If I had known about this incompatibility, I would NOT have purchased the update to 7. I am now considering a more expensive option of C4D.
I feel duped.
