3D printing with 'hide' display ok but print as solid black!

[TomDM]

I have made a simple 'box' in draftsight 'Model'. Selecting sheet, and rotating xyz to my desire. when printing looks ok. Then I use the 'View/Hide' command, and the hidden lines related to the view does disappear. When printing, the box become one big black solid 'bar'.

How can I have this sheet print correct?

hope someone has a good idea to solve this
