The long list of inquiry tools within AutoCAD provide many ways to approach the task of performing quantity takeoffs on your drawings. Yet as powerful as these tools are, one limitation that has long challenged me is way 1 doesn’t always equal 1 in the context of quantity takeoffs. A common example of this is the need to calculate the number of parking stalls throughout a site. Because of site design elements such as parking islands, it’s likely some stalls will not have a painted stripe separating it, meaning it’s not necessarily possible to get an accurate count by simply calculating the number of paint striping lines in my drawing.
Despite this limitation, one consistent parameter with parking stalls is their width. It stands to reason that an accurate count could be achieved by adding up the length of a parking stall run, and dividing it by the width of a single stall. Interestingly enough, this can be automated using a lesser known Conversion Factor parameter for Fields.
