You may have noticed that tabs are a little different in AC20, as some have mentioned. The intent is that they are supposed to be a little more intuitive, and certainly are more flexible once you get the hang of them. Here are the key differences in this feature:
Eye Dropper/Inject View Settings
You can now use the same “pick-up/inject” parameters system used between all elements placed in ARCHICAD, for the view settings between tabs. Injecting the new tab with new parameters does not affect the View Settings, but only changes the viewpoint settings (like the project map navigation).
Injecting view settings into a tab will make that tap a Viewpoint, rather than a view. In order to revert back to the original view settings you need to navigate back to the View Map origin.
Double Click/Single Click Tabs
Double clicking the tab will still revert it back to its view, where single clicking will maintain any the previous Viewpoint settings. Single and double clicking tabs is one feature of the tabs that has changed most significantly. The big improvement here is that each tab, wether opened from the Project Map (Viewpoint) or View Map (View), each tab is able to retain its original view settings. This means that if you open a floor plan from the view map, then switch to a new view (3d, elevation, section), that view is not dependent on the previous tabs view settings.
This also means that navigating between tabs by shortcut does not maintain the current tab’s settings. To match a plan to 3d tab if they are not from views with matching settings, use the eye dropper/inject between tabs.
Right Clicking Tabs
In AC19, there were very limited right click options when clicking on a tab. Now, depending on the tab’s source (Project/View Map), and content, you will get a range of options. If the tab is a Viewpoint, you can actually search for saved views using that Viewpoint by right clicking on the tab. You can also open tabs with current windows settings, right click to get to Pick Up / Inject, and more.
As in AC19, you can still right click an open tab to show it as a trace reference for the currently open tab. There are several other options added to the right click drop downs, such as “Match all to Current” and “Get Last Settings”.
One last minor feature of the tabs in 20 is the less alarming “!” symbol indicating that the View originally opened for that tab has changed and the tab is currently operating from a custom Viewpoint rather than a saved view setting.
