I'm using named plot styles (*.stb) in Acad2005 and encountering some troublesome issues. I have a certain plot style assigned to my dimension layer; color blue, lineweight lighter than objects, whatever, etc. Problem 1: If I dimension using closed arrows (not filled), the arrows insist on plotting by object color while the rest of the dimension, (extensions lines, dim line, and text), plots correctly as defined by the plot style. But if I use closed filled arrows, they plot correctly according to the plot style. Strange. Problem 2: When I insert a block with attributes on the dimension layer, it plots with the wrong plot style, not the one assigned to the dimension layer. When I check the properties of the block, plot style is set to by layer. Strange. Problem 3: My title block is an xref on layer "title" which uses the same plot style as the dimension layer. The xref has two nested blocks, one with attributes for the title block info, the other a company logo (not raster). The title block and the attributes plot correctly with the style assigned to the layer but the logo plots by object color. Pete
