Dears,Good Day.I am working on a large scale GIS project where i have to load multiple drawings into my working area.Here i am requesting for a tool which is used to load drawings(2*2KM)  sheet data/drawing into a work area drawing.Brief intro about my project. We have 500+ Sheet data or drawings which is 2*2KM in size. Whenever we want to refer any area we always depending on grid number xref and identifying the grid number and loading the sheet. to eliminate this i want a tool which can read the geo location and load the related drawing of that particular area.I have zero knowledge on tools creation but interested in learning tools customization as i have a list of tools requirements which i want to implement in my current project.Any guidance is appreciated in this regards.Thank you very much.Krish.

If there is a clear method how to construct a filename from the location you want to load (a grid number, a range of X/Y coordinates, etc.) you can use a simple LISP macro to create the filename string and then call -XREF or FILEOPEN to open that file.
