Class visibility in the standardsIn the class section of the Layermap worksheet, class names available for inclusion in the viewports/views are listed down the left side of the worksheet in the first column. The visibility of a specific class is indicated by an alphabetic identifier, which is located in the worksheet cell which cross-references the layer and the viewport/view.
The identifier can take on one of the following values:
