Hello, My CTBs seem to have stopped working (ACAD 2005). I've been plotting fine from this drawing, then without warning, all my CTBs (I can see them in the list) started plotting as if set to "none". Even the default "grayscale" plots in color. This problem is drawing specific as as I can plot fine from other dwgs. Interesting side-note...if I set the "plot quality" to "draft"...the plot works. Thanks. Jeff
