Please McNeel, take this seriously! We are wasting so much time in our architectural office because of exactly this one bug.
There are numerous other issues regarding layouts, but THIS is the most pressing one.
No, this does not help! You do understand what the problem is, don’t you.
The moment you cange layer visibility in model space (which you need to do when modelling), you change it as well in all Details! This is NOT good!!!
The layer settings in the Detail are remembered, yes, but since the master layer toggles have changed during modelling, you need to tediously ‘restore’ layer visibility in Layouts/Details before print.
It not as simple as just turning on all master layers, because there might be layers that should remain turned off everywhere, even in model space.
Also, using Layer States is not a good solution because there’s too much concentrated hassle involved in doing so.
Possible solution 1 (that I can think of):
In MODEL SPACE, add a SECOND COLUMN of LIGHTBULBS - the second column would toggle layers in model space ONLY. The first column would toggle everywhere, just like it is now - this can be desirable also!
All commands related to layer visibility would have to be adapted (OneLayerOn etc.), so that they either work for the first or second column of layer toggles.
It would be quite logical that way - every Layout, Detail and also then the Model space would have their own dedicated layer toggle lightbulb - plus one master toggle that affects everything.
Possible solution 2:
Every Detail gets a new property called something like ‘Override Model Space Layer Visibility’, which does exactly this. If this is on, the Detail layer toggles will be unaffected by the model space layer toggles.
So, if you dropped what you were doing and tended to THIS issue, you will hear the cheers of your users across the atlantic! =}
Thank you 1000 times!
In fact, AutoCAD has the same problem (I checked): turn off a layer in model space, and it’s turned off in paper space also. Not so much better.
Regarding this, ACAD and Rhino are very similar.
