Contractors and project managers use blueprints to calculate the quantity and dimensions of materials and supplies needed for the project.

How many objects. Right now the model is quite simple, consisting of only concrete and drywall. A very frustrating day, completely wasted. ato file is over 44MB, but no one is home. Something loaded, but all commands are greyed out, there are no documents attached, and the workbook is empty. When I opened the project I had just completed THERE WAS NOTHING THERE. At the end of the day when I finally finished mapping the items, QTO crashed. Each change for each item took several minutes, or hung altogether if I tried to map too many items at one time. Mapping the takeoff items took even longer. This imported after several hours, and required a couple of more hours to perform a Model Takeoff (51,101 Objects). The next attempt was with the 240MB project with no links (I bound the (5) links into a single project).
QTO hung whenever I tried a Model Takeoff. Managed to import (after a couple of hours) after exporting again using. The first attempt was exported from a Revit Arch 2009 project that consisted of (5) linked projects ranging in size from 12MB to 124MB. Moved to a faster desktop (quad core) with 8GB memory running Vista Ultimate 64-bit. I started using QTO on a fast laptop running XP Pro w/2GB memory. Two days of unsuccessful attempts to process DWFs from a 240MB project are leading me to believe that QTO as a product is not ready for primetime.įirst I created a 3D DWF and a 2D DWF with (18) sheets representing the (18) floor plans. QTO worked fine with 2D and 3D dwfs exported from a relatively small (45MB) project when we tested the product before purchase. I've been attempting to use QTO to produce a takeoff from a Revit Arch 2009 model, without much success.
