Graphic override - layer combination problem

Barry Kelly — Tue, 23 May 2023 14:14:43 GMT

I would just like to check if I am doing something wrong here before I report this as a bug.

I am trying to set up a rule that changes the pen colour of an object when a certain layer combination is turned on.
But no matter what layer combination I have set, the colour is still overridden (see attached image).

Am I barking up the wrong tree in expecting this to work?

If I change it to "Layer" it works as I would expect.

And then oddly if I change the rule to "Layer Name" it doesn't override at all.

What is the difference between "Layer" and "Layer Name" except with the latter you must manually type the name in and it gives you more choices rather than just "is" and "is not".
More choices but it doesn't work.

Hi Barry, because ARCHICAD Layer is a special layer I think it’s not as simple as typing in the name as you see it. Try typing another layer that you have created yourself. Also, Layer Name allows you to include a bunch of layers using contains or starts with. But the Layer just allows one layer to be picked, and you’d need to manually add more criteria to include more layers - which can be more cumbersome.

Thanks James.
Yes using a different layer worked - I didn't think that "ARCHIAD Layer" only appears to be called "ARCHICAD Layer" but that is not it's real name as far as Archicad is concerned (that has caught me out in GDL before).

But it is my initial problem I would like to clarify - the use of layer combinations.

This would be perfect if it id work as I want to hide specific objects in a specific layer combination without having to create a new layer that I can hide.

Just experimenting with making a new classification and hiding (making white) if that classification is set.
Seems to be working fine, but it would be so much easier if the layer combination worked as that is already set up in all my jobs and all I have to do is add the Graphic Override.

That's clearly a bug.
The override is either always on or always off, as far I can tell.

Hi Barry, I haven't had a chance to spend time with AC21 yet but have you considered that the logic of the conditions may be different. Could it be that the conditions check the visibility of the layer within the named combination only and not which layer combination is currently set?

For instance if your object layer is hidden in combo B then although it is visible in selected combo A then it may not be affected by the GO and if visible in combo B then it would be affected by the GO.

Never worked in AC20 as well. So this bug is not specific to 21.

It should have nothing to do with the layer visibility (except the obvious if the layer is on the object shows, if it is off then it won't).
To my understanding it should simply be that (assuming the object layer is visible in all layer combinations) if the layer combination is active then the object should be overridden.
If a different combination is active then the object will not be overridden.

This is what I am trying to determine - is this what should be expected - before I report this a s a bug.

I understand your logic Barry and can see how you would apply it, but I don't see the advantage. If something is visible you can filter it out to apply the relevant GO rule irrespective of the layer combo and applying the required GO to the current view. I must admit I hadn't considered using the layer combo as a filter, but even so, I do think the logic for me would be to check if the object is turned on in a combo irrespective of what combo is selected as this would extend the filtering flexibility. For example you could highlight objects in the current view that shouldn't be visible as they were only supposed to be displayed as part of the fire strategy combo, which is probably more in line with BiM analysis thinking rather than presentation.

I did find this page which kind of supports my option but isn't totally clear and I still haven't had a chance to test it so you you may be right and it could be a bug...

Yes it can be done by filtering in other ways but the layer combination would be very simple for my situation.
What I have is a floor waste object that is shown on our floor plans.
But for our electrical plans it is not really necessary so I would like to hide it.
Yes I could create a new layer, put the floor waste in that layer and update the layer combinations - but I am talking about 100s if not 1000s of existing jobs (project home builder).

Using the layer combination in the graphic override would mean simply importing an amended GO (or just adding a new rule) that makes the object white when ever the electrical layer combination is active.
Same object, same layers, same layer combinations - just a tweak to add a new rule to the existing GO combination.

What I am resorting to now is a new rule to filter the object by name.
However this means that I also have to create a new GO combination and apply it to my electrical plan views.
So a little more work.

Just trying to simplify it as much as possible and not confuse or create too much work for our 60+ users.
