How to reset classes from imported DWG files

[Camila85]

Hi,

 

I've been working off a floor plan I imported from an architect who I assume has been working in autocad. I'm quite new to using classes but thought it would be useful for my lighting/ labels/ flooring patterns so I can turn them on and off without it looking too busy. I've assigned the lighting a new class called "lighting" however nothing seems to happen to the visibility when I turn it on / off. I can see there are load of random classes that are in my list from the imported doc, I feel like maybe items are in several classes/ symbols which is messing up my class assignment. Is there a way I can clear them of all their current assignments? many thanks

I would start with the purge command to see if some classes are imported but not used. Then you can choose the class you don't need and delete it, you get an option to replace it with some of the other classes.

I ended up deleting the old classes one by one, however i've classed the lighting symbols but they dont seem to disappear when I turn off the visibility? I'm relatively new to Vectorworks, have attached the file if that makes more sense. Any help would be greatly appreciated!

@Camila85 This is happening because your active Class is Lighting.  Vectorworks always shows the active class regardless of its visibility settings, which makes sense since you might start adding things and they would just "disappear" if the class was not visible.  So, just pick another class to make active and your lights will turn off.

 

You will then see that you have an elevation drawn on the Lighting class that disappears too, so it might be a good idea to review how you have been using classes so you don't get more unexpected behavior.

This was super helpful, thanks so much!

if you know what classes you need to change, you can set up the mapping of the classes as you import the DXF.
