I'm a pipe organ builder who uses AUTOCad for all my drafting and design work. Since organ pipes are mostly round, I'm always drawing circles. I'd like a program to run in AUTOCad (2010) that will allow me to batch import a list of circle diameters from a spreadsheet. The program would draw the circles with center marks, and add a text label inside the of the circle. This label would also be imported from the spreadsheet (text size scaled to circle size). Each of these (circle/center mark/text label) would be drawn as a block within a single file.
