Attempting to get silhouettes - which are detail view window specific - out of model space where they appear in every other detail window unless they (or their layers) have been specifically hidden.
Shown in blue for clarity is the result of running Silhouette on objects in a detail window. Pretty good thick lines on every 'cutting" edge.
But they now show up unwanted in every other detail window.
The only remedy I can see for this is hiding every silhouette layer or line in every detail window except the ones they’re generated for. Unfeasibly labour intensive on a multi-windowed, multi-paged project.
So I look to get silhouettes, as coplanar vector lines, into layout space where I can put them only where they’re required.
ChangeSpace (below) brings silhouettes into Layout space for editing, but it includes all hidden lines. Unfeasibly labour intensive to remove.
Make2d (below) generates coplanar lines I can copy, paste into Layout space (and scale), but it only puts a silhouette around the entire collection of objects. (even if the Silhouette-generated lines are included in Make2d’s selection set.)
