Visibility of Drafting Primitives

The derived visibility of a drafting primitive can be extracted into expressions. The attribute name is PRMVISIBILITY. The attribute value is TRUE if all owners of a primitive are visible. For a primitive or Vertex below a VNOT, this means that PRMVIS is TRUE if the VNOT, LAYER and VIEW are all visible (for example, if their LVIS attributes are all TRUE). PRMVIS is true below a NOTE if the NOTE is visible, and PRMVIS is always true below SYTMs. For example
