I am working on a project that has a number of surfaces, sites, and gradings. Everything was organized in such a way to make their association respond properly like - surfaces made from gradings only from one site and then a final surface compiled of pastes. Everything was fine until the other day when grading infills started disappearing, a pond on its own site made of a few gradings wont show itself as a surface with contours - when I pick a grading diamond and look into the properties manager the "Group" field is empty despite having set it when initially setting up the Grading creation tools options. Has anyone encountered this issue? what am I missing and or doing wrong here? This all seems to have "just started happening" the other day, is 27 surfaces and 17 sites too heavy for one drawing? ( I don't really think that's true, but im stumped.)
