That you have Gerber files that open nicely in Gerbv does not mean that
AD21 can import that. :-(  I had such a case last week and opened a discussion
about that.

Gerber files usually have no drill information, although my example shows at
least some bounding box. Relevant key words are drill file, Excellon etc.
In AD the generation of drill files is a work item at the same level like
"Generate Gerber" under "file/fabrication outputs".
The file extension is .txt, wich is not exactly a great help.

It seems that importing DXF creates less errors than Gerber.
I worked for me with some manual post processing.
