Evening all

Just come across a problem that a fellow caddie has asked for help with, that I've been able to fix for him. Essentially, when printing a 2D background through a viewport using Legacy Hidden (so that the 3D content shows correct hidden detail and blanks out the background underneath), any 2D arcs with a linetype will print as continuous.  The same problem can be replicated using the HIDE command.  All linetypes and ltscales / lt variables are correct.

He's using 2018 and I don't recall noticing this issue in previous releases.   Is this a bug in 2018?

Any and all help much appreciated.

Many thanks

Graham
