I want to print the drawing from the paper space, but I have there thick lines of attached dwg files. In the model space everything seems to be OK. Do you have any idea how to change it?
Are you using plot styles? In the plot dialog you can select not to plot using plot styles or use the standard acad style.
Thanks for your answer. I tried to set plot styles but I think that the problem is creating by blocks which are in the attached drawing (perhaps some settings of plot are connected to the settings of blocks).
