DWG Files open without showing all information
I have been sent and successfully opened several DWG files recently. When I open them, I see shape outlines (for mineral claims), a scale and nothing else. However, only by fluke, I discovered that a particular DWG file had a map and a legend within the file. Using different DWG programs (like irfanview or DWGsee) I can clearly see the extra data, but when opening the files in GM12 the data is invisible. Why is this and how can I fix it? I have missed out on some very valuable data because of this issue, and the worst part is I had no indication that anything was missing.
