I’ve read all the help topics on this subject but I am still having trouble making lines show as dashed. I have grouped a number of lines, applied a tag to the group and selected dashed in the tag. I think the issue is in the Style editor, I can’t see the checkbox to select dashed lines?
I am not sure about how to use styles, I think I understand the use of the outliner and tags (with groups and components), but styles is something I need to look into more.
The thing about the sketchy line styles including the straight line styles like the one you showed in your screen shot is that they use .png images of strokes to replace the normal edges in the model. Those won’t show the dashes and the settings that are available are different as you can see when you compare my screen shot with yours for the Edge settings.
