Yesterday I had gone through a drawing with a storm sewer netwoek and gave each structure with a Surface Adjustment Value of -0.1' under the Part Properties tab od the Structure Properties Dialog Box. The adjustment had worked properly and I saved the changes to the drawing.
This morning I opened the same drawing and found that the adjustment was not applied properly. The value in the dialog box was still -0.1', but the actually adjustment to the rim elevation was +0.1'. Re-entering the value in the dialog box changes the rim elevation to the proper elevation, but this took extra time and had I not caught the software error, the inlets would have been staked wrong in the field, and that would have been really costly.
