Grey Class does not work

[CS1]

I have created a basic model with the following layers

Mod Site

Mod Ground

Mod Roof

I can easily view in 3D and say change the visiblity of the "Mod Ground" to grey, the layer now appears to be transparent and grey.

If I try to change say the class "Roof" or "Site model" or any class to show as grey it has no effect. Am I doing somthing wrong?

[CS1]

In View>Class options> I have chosen Show/Snap/Modify.

In navigation I have chosen show as Gray

The active layer will always render 'solid'... Does that make sense?

[CS1]

AH HA thanks didnt think of that i'll try changing active layer and see if makes a difference

[CS1]

I have tried switching layers and makes no difference. I have even tried switching all classes to gray and makes no difference when updating.

Try changing your layer viewing option to "Gray Others" (or "Gray, Snap Others) and setting each individual layer to "Visible". With those options selected you *should* see all but the active layer as gray/translucent. The active layer, as I said before, will always show as visible/solid.

Let us know what happens ;-)

Yeah no joy, If i change the visiblity of a class to visible or invisible i notice a change but if select gray then no change. Tried creating a basic model using just cubes with 3 different classes and three layers but cant get the gray classes to work

OK wait. In re-reading your original post I noticed you talked about gray classes AND layers. And I was assuming you were asking about layers only.

It might be helpful if you could explain exactly what you are trying to do...

But if you are trying to be able to see through some objects and have others solid (like see through the roof into the plan), then I think you'll have more joy using layers than classes. Using layers you can achieve the following:

However, using classes the result is somewhat different...

Yeah i know how to gray selected layers so as you say i could see through the roof into the plan but would be handy if I could gray classes also, not sure why I would use it yet, maybe if i had the building visible with all the concept objects like cars plants etc in a concept class then i could show those concept items as grey
