Hi -
Yes, of course. But what I said was:
You didn’t mention a layout in your first post. Layouts are set to the “Wireframe” display mode, and when printing a layout as vector output, all curves, hatches, and annotations that are created on the layout will be printed as vector. If you were to create a surface on the layout, you’d get vector output of the edges and isocurves, but no “surface” (color, shading, …) will be printed.
When you put a detail on a layout, you typically set the display mode of that detail to some “shaded” display mode. Up until Rhino 7, whatever display mode (apart from Wireframe) you picked, that detail will always be printed as raster, also when vector output is selected.
You should probably provide a layout from Rhino 7 with non-wireframe details, but are you referring to geometry on the layout or geometry you see in a detail on a layout?
What is new in Rhino 8 is that any detail on a layout that is set to any of the technical display modes (Technical, Pen, Artistic, Monochrome, and any modified copies of those) will result in vector output when printed as vector. This is something that has been on the wishlist for over 25 years, and, yes, is not completely perfect yet.
For the time being, if you are happier with raster output of details on a vector layout than somewhat unfinished complete vector output, you could modify a rendered or shaded display mode to look somewhat more like a pen mode.
In the Rhino Options, change the update frequency from “Service Release” to “Service Release Candidate”.
