I would have a problem, to replace all lines of a design with certain thickness polylines, it is terribly tiring to select them to one by one
Thank you.
Hi.
mpedit command of the express tools.
transforms all lines in polylinee. then the selections all and in the properties give him the thickness.
this presupposing that in the design there are only lines and not other entities, you see arches, as it also converts those.
in this case you have to use, to select only the lines, the selerapid command.
