Trying to grey out classes

[lolo66]

Whenever I try to 'grey out' a class, for example (and i've linked an example vw doc) when i'm tracing over a scan and I want to grey the scan out so it's easier to draw over, I just get a box with an X in it when I select the grey icon. 

I know it's probably something really simple but i've tried googling the problem and haven't found a solution yet.

Thank you!

Hi

Vectorworks is only able to grey out actual geometry. Image files such as jpg's just show what you are describing.

If it is an Image underlay you would set a Class Transparency to make it less distracting to better
see what you are drawing.
Same for referenced geometry that you may bring in as a viewport. Sometimes the gray option
will hide too much and make it unreadable. So transparency may also help.

Would you mind telling me how I set a class transparency? I've looked online for help and i've read that there's an opacity setting in the attributes palette but I can't find it. 

Thank you,

Tools > Organization > Classes, select a class and click Edit, you should then see the Opacity slider.

It can be done from the Navigation palette as well if you have that, right click on the class name and choose Edit.

Aha I realised what I'd done wrong now. Had tried the method above from Jim W but hadn't set Use At Creation. Thank you for your help!

In addition to setting the transparency of an entire class, you can select individual objects and change their opacity in the Attributes Palette (which you mentioned earlier):

(The opacity portion is highlighted in yellow.) If you see the little curved arrow, that means the particular attribute is "listening" to the class to which the object is assigned. Clicking where it says "100%" will give you a pop-up where you can lower the opacity or determine whether or not it's listening to the Class's attributes.
