Curves in nested blocks invisible when printing due to clipping planes

I can’t seem to print curves in doubly nested blocks (curves are in blocks, which are inside other blocks). Hatches show up, but curves are missing unless the blocks are exploded.

Hi Daniel -
I can’t seem to reproduce that here with a simple test

Could you post a file that behaves as you describe?

You are right, the problem was in the clipping plane. Nested blocks don’t show in vector output only when clipping plane goes beyond the origin point (w0,0,0).

If there was any way to fix that, it would be really helpful.

@Wim I found out that it’s ModelBasePoint that determines it - nested blocks that don’t have modelbasepoint within clipping planes don’t show when printed. Expected behaviour though would be that even if blocks modelbasepoint is at origin clipping planes wouldn’t hide them when printing. I’ve sent details of the problem via a direct message (hope you don’t mind).
