I have a few thousand drawing that I need to get info from, create a register of the files ready for uploading into a SQL server database.

I have about 95% of it complete but some issues have me a bit stumped and I was hoping you good people might be able to point me in the correct way.

Problem is that the drg numbering system uses the drawing size as part of the drawing number. Some of the drawings we have been given don't have the drawing number formatted correctly so I can't get it straight from the drawing. I have a function that works out the size of the drawing regardless of orientation if there is a scale on the title block. Some of the drawings don't have the drawing scale on the drawing and they haven't used the dimscale.

Is there any way I can work out the scale factor of the drawing that will then let me work out the drawing size?

Thanks
Robert
