Sublevel walls visible when printing vector output

Hi,
I have a model of a house with a basement and a main level. Ive been printing lots of plan drawings of the main level without any issues but suddenly it has started printing the basement walls on the main level drawing. Ive tried drawing a new floor slab between the levels. Tried switching floor slab type. tried changing the slab to different projection modes. Made sure the slab boundary is set to print. Made sure that the hidden view setting are at default. Made sure that the levels are rightly set. Made the slab core and the basement walls ‘normal’. I cant think of other things to try. When i print raster output it rightly doesnt show the basement walls. I take any hint or suggestion with very open arms.

Hi @Jens_Jacob_Melhus_J1

To help you better solve the issue, could you please share the .3dm file?
You can either send it to visualarq@asuni.com or upload it here.

Best,

Hi Melissa,
After a couple of hours of trying to solve it i gave up and instead hid the geometry in the basement level. I clicked show and kept working on the model. Suddenly the issue went away by itself. It prints fine now - is that even possible or have i done something?

I wish it hadnt solved itself so i could send you the file.
