MAKE 2D of Blocks

I have noticed that Make2d works better if you explode all of your blocks. it will leave out blocks completely or it will make2d of something I USED to have in that specific block OR maybe it’s a hidden layer - I can’t figure it out… it’s not visible but when I MAKE2D it comes up? So I need to EXPLODE the blocks which kind of defeats a bunch of purposes for me…anyone else notice this??

Hi - I’m not able to reproduce that with a model here.
Please run the Rhino SystemInfo command and post the result here. Also post a 3dm file that is misbehaving on your system and provide clear steps to reproduce the issue.
