It's so important to consistently use classes when you creating drawings. if you're not consistent about using classes, you going to have a lot of trouble making sense out of your drawings. You will find that things you want to appear don't, things you want show up won't. Then you'll say that Vectorworks is difficult to use. It's not Vectorworks's fault, it's your fault for not being consistent with your classes.
