Problems Counting More Than One Sort of Joist. When you set up one of the quick reporting worksheets in Vectorworks, it’s common for you to count too much. In one of the other Short Sharp Manuals, I showed how to count up all the joists in a deck (patio). That worked because I Only had one sort of joist in the file, but what if you have more that one sort of joist.
The answer is to have more that one class, and use the class as a criteria to find the joists you want.
