one pitfall you may likely to experience if you are green is to have annotative dimensions and not be in the proper scale. you can try toggeling (switching the variable from 0 to 1 etc.) ANNOALLVISIBLE https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoC...
