Hi there!
First, THANK YOU FOR THE MAC 6 WIP (and all the work that has been put into it)
Second,
It is impossible to really delete a Layout.
- Create new file
- Create any geometry
- Create new layout
- Delete layout
It only seem to delete the preview, not the actual layout
Rhino WIP 6.10
MacOS 10.13.6
Keep up the good work!
EDIT
After further toying with the WIP.
It seems to be a “layout refresh” issue.
After creating and deleting the layout, if you quit the layout window, then reopen it, the deleted layout is now gone.
