Just recently civil 3d stopped being able to find the current drawing when I do a data extraction. If I choose by drawing it show all the blocks ect. and thier extractable attributes. but when it trys to create the table it can't find the drawing! The drawing it is looking for is the drawing that is open (The current drawing) What would cause this? any found a solution to this? up until about 6 months ago I could extract data using the whole drawing. now I can't.
Any help would be greatly appreciated.
