How to set drawing to use one lineweight

[Anonymous]

I have been making changes to an old drawing, and only realised upon printing that the new lines were thicker than the old lines, is there an easy way to change the whole thing to the original lineweight? When I select all and go to properties it says that there is no selection

Hello..

this occurs because there are many items selected ...

what you can do is select all and change the properties in RIBBON, not properties.

when printing, your lines are controlled by by layer colour and plot style table pen assignment. thanks

Hi,

>> ....and only realised upon printing that the new lines were thicker than the old lines,

that depends at the way that you plot with ? did you use a .ctb plot style file ?

As @MatiasWendt mentioned you may be trying to select beyond the limit. You can change the limit to see if that would work. https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoC...

I would also look into MATCHPROP
