Projection lines visibility. in general modell family

[Darwin33]

I have just created a 3 d familly as a general modell to be placed 2 meters over the floor. In 2d view plans this should show like a dash lines, but it doesnt, it appera as continuous even it is not cut. I also tried to draw a simbolic line in the family but it doenst work either, it shows also a continuous line. 

Any clues on this?
