I'm trying to print in a svg image, but in a new layout I cannot get the lineweights I have in the default Sheet 1 and Sheet 2, the only way I can get the entities Lineweights is in the print configuration in the additional options selecting not to use any print style, but that's not my case, i need to print with monochorme, everything is default, even the linewidhts are assigned like that "to print Entities lineweights". WHAT HAPPENS?   

Even If I make a change in any print style the preview doesn't give signal that something has changed, example the color, always prints black...

What happens? Why I only can print with the correct linewidths in the only 2 default layouts? it is a bug?  It is incompetence from dassault developers? It is incompetence for the autodesk drawing format? what is?.
