Autocad Mac 2020 Dashed lines

[lwilliamson32 0]

Hello,

I am running Autocad 2020 on a Mac OS. I am trying to turn all of my lines in one layer to be dashed instead of continuous. I loaded in a dashed linetype and have applied it to the layer I want. It doesn't change any existing lines to be dashed and doesn't make any new lines, polylines, splines, etc. dashed. It doesn't appear in model space, layout space or when I plot the layout. 

 

Is there something I've done wrong? 

 

Thanks for the help!

Did you change the LTSCALE variable? 

What template file did you use for your drawing (acad.dwt or acadiso.dwt)?

Like Remark Acad.lin or Acadiso.lin makes a difference as in simple terms metric or imperial. Which is loaded ?
