I have 3D Polygons selected, each with a correct Z value. I validated the data. I go to create the Site Model. I adjust the settings and click OK. VWX is stuck on Updating Site Model in the bottom right corner of the screen with the progress bar showing blue across 1/8th of the progress bar. Need help. I've forced quit three times and every time, I get this result. Using VWX 2016 Architect on an iMac OS X 10.10.5 Yosemite.
