I've been a satisfied user of Nanocad 5.0.2520.1471 Build 2000 (free) for months, but lately I get a critical compatibility problem with Autocad.
Every dimension created in Nanocad (even starting from the standard black template) gives an error if copied / trimmed by Crtl+C / Ctrl+x in Autocad (mechanical or standard).
Dimension and its properties are correctly displayed in Autocad, but if you try to copy it the program pops up a generic message "Copy to clipboard failed".
Of course no error happening in Nanocad.
This compatibility problem has been reported by a couple of customers already, using different versions of Autocad, and I can say it started a couple of months ago as I use Nanocad since months for quick editing of less important documents and never received a bad feedback.
You can find a basic file that shows this strange behaviour
Thanks in advance for the feedback
