Hello, I have a question, I new with VectorWorks, so maybe it's a silly question but, how can I hide lines that I don't want to see in a section. for exemple: the conection between the wall and the slab, creates a line. How can I hide that line? I used to use Revit and it was easy to do it, but in Vectorworks I can't find a option to do it. Thanks in advance! :) Cheers.
