Site Modifiers not showing new contours in Site Design Posted April 6, 2012 Was a solution found, I am having the same problem?! Yes, the issue was that I had accidentally moved some pads so that they touched or slightly overlapped each other and that is not allowed in VW. When those pads were moved slightly apart, and then clicked Update Site Model, the contours appeared correctly. Thanks to Peter for helping to figure this out! Looking back, it also might have been better to have separate boundary objects around different parts of the site that are regraded, instead of around the whole site. That could make troubleshooting easier by isolating any area that you just editted. Of course, that would only apply to renovation type projects, not brand new sites that are entirely regraded.
