Problem

The maximum value for my contours is not showing up when I use the contours browser. For example, the maximum value in my contours is set for 3,000 gpm and the maximum contour value line showing is only 2900 gpm, but I have junctions that have a maximum of 3,000 gpm.
Contours not showing up in plot preview / plot. When trying to plot a WaterCAD/GEMS for AutoCAD model, the contours do not show up.

Solution

For maximum value query, make sure the maximum value in the contour manager is set slightly higher than the value that you want to display. For example, if potting contours the fire flow (Available) and the upper limit is set to 3,000 gpm and you want to display that value in your contours, set the maximum value in the contours manager for 3001 gpm or larger.
For contours nor displaying query, first, try exporting the contours to native format. This is done by right clicking the entry in the contour manager (View > Contours), then choosing to export to native format. If this does not help, please upgrade to the latest version of WaterCAD/GEMS and apply the latest corresponding cumulative patch set.
