In AutoCAD 2006 the dimension text and arrowheads appear hollow (no fill) when you hide the viewport or plot using hide. This is a 3d surface model dimensioned in model space. When the viewport is plotted in hide mode the fill of the text font is missing as well as the arrowhead fill and other blocks with polylines also appear hollow. I've tried setting the viewports shadeplot setting as well as textfill with no success. Any other ideas?
