In Layout View, my viewports are not showing the correct color pen sets... They should be showing with the "Layout" pen set, but instead some are showing with the "View" pen set. And the funny thing, one is showing up correctly while two are not, all on the same page. I've made sure to go into the view settings and change all to the same one, so I'm not sure why they're showing up differently.... See the image provided...
My understanding is that you can use for example a penset that uses colour to indicate line weight (eg green for 0.18), then rather than altering your view each time, you can choose to have your drawing on the layout use a black and white penset. Alternatively you can manually set all your sanitaryware items to use a different colour pen, but then have them black on the layout.
Our preference is to work using the same appearance as the finished product and use graphic overrides to emphasise various elements, rather than manually make those elements have a different 0.18 pen, hence why my screenshot only had the one "Default" penset. The "Legacy" one is just kept there as a "just in case".
I generally understand that, but my problem was that I was trying to change the viewport's pen set by right clicking and changing it through the "Modify Source View Settings" dialogue box, which wasn't working. It's kinda frustrating that Archicad has multiple ways to change things, that sometimes work sometimes don't....
You need to define your saved view with the correct pen-set before placing it into a layout. Or you can trace back the source view (select the layout drawing > right-click > open source view), change the pen-set and then redefine the saved view.
Or, like @Josh CSNZ indicated, you can select the placed drawing on the layout, go into settings (crtl+t), and select the desired pen-set there.
