I am a Land Surveyor and commonly work with DWG files from day to day using AutoCAD to run them. In short DWG files contain map/drafting data in a non-ASCII format. You cannot open them as plain text.
The other day I came across behavior in the DOPUS file search that is very interesting to me- if I search for files containing text "CS_PROJ ZONE" in the containing text for simple file search, it returns my ACAD drawings. I know this text to be a variable name for the value that determines the State Plane Coordinate System the drawing is set to. I have no idea why this search pulls up the DWG's, I can only infer that it searches beyond plain text. Now what I am hoping for is to use this search behavior to set a column script to display a DWG's coordinate system based on the drawings value.
And you may now see my problem, I found the variable name with search but have no idea for the syntax of the next lines and how the the variable value is stored.
Does anyone know why the search function would read an otherwise unreadable document and have any ideas as to how I may find the stored value/extract the line the found string belongs in?
If I can figure this out I could theoretically make this work with any similar kind of stored variable in ACAD, which would be amazing!
