This is just one of many bugs since we have installed 16. When trying to copy linework and text between two projects using the clipboard, 16 flicks between the two windows of it's own accord and then doesn't paste the objects.
Works here, are both projects set to the same Renovation Filter?
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
Thanks David. Signature attached. The renovation filter is the same. After I paste the item it instantaneously disappears and changes my window to the project I was copying from. Strange days indeed.
It would be nice if you could help us to reproduce the issue. If the problem still exists on your platform, please record it and send the video to your local distributor: http://www.graphisoft.com/support/archicad/
Are the texts and lines imported from a DWG file?
