We do something like that here by laying a pictureframe on the ground plane. Then in the layout view there will be a set of detail views with “pen” hidden line drawings, other pictureframes, and one detail that just shows the pictureframe on the ground behind everything. Much simpler and I found that the pictureframe will print to pdf much crisper than the same image in the background view(at least with Rhino4).
Thanks Pascal,
sorry for pushing this thread in a rude way but I have a big company asking for this to be solved.
Please could you let me know when this will be solved? A reply to this post it’s ok.
