MACH PROPERTIES

Hi everyone!!

From time to time the MATCH PROPERTIES command doesn't work properly on my computer. I use it quite frequently but sometimes it doesn't match the thickness of the source line. I have already check the match properties settings, all of the options are on. I also try to switch off Autocad and start again but doesn't work either. What can I do?

Thank you for your help.

are the same type of elements what yoy are trying to match, ie polyline to polyline?, and not a block or other element?
