In ACLT14, where is the option to add new view windows on a sheet? It appears to be either missing or greyed out on my screen.
The catch is in the title of the panel with the greyed-out options: "Model Viewports". Those tools are for working with viewports in model space, which is why they're not available in paper space/layouts.
Check out the "Layout" tab instead for layout viewport commands. (You'll notice that those commands aren't available in model space too.)
In model space, the model viewports panel is enabled. In layout/paper space model viewports panel is disabled, which is ok. But there is no layout viewports panel, or Viewports Panel as described in the help for "To Create a New Layout Viewport", when focus is on a layout tab and in paper space. That panel is missing. A workaround might be to use the command line alternative, or to change the "user interface". Whether this behaviour is a side effect of an upgrade of an earlier version, i.e. an adjustment of the user interface to an earlier version, or not, I don't know. I could not find a way to add the Layout Viewports panel either.
(This regards AutoCAD LT 2014 SP1.)
When following the instruction to check whether Layout Viewports panel is enabled or not in the View tab, I can only find that all available View tab panels are enabled, and among them is no Layout Viewports panel, only the enabled or disabled Model Viewports panel.
The attachment (pdf document) contains some images (only snapshots of AutoCAD LT desktop, and explanatory text), which depict my attempts to find and enable a Layout Viewports panel.
Layout viewports can also be created as a workaround, using MVIEW, for example following this procedure:
However, the object(s) created in 1 cannot be deleted, without deleting also the viewport, it seems. Highlighting the viewport and deleting it, will delete the viewport, but not the original object(s). Using the Home → Erase button and selecting everything within a selection window will delete both the viewport and the original object(s).
When I first installed AutoCAD LT 2014, or when I opened it for the first time, it asked me whether I wanted it to adopt to my previous installed version (AutoCAD LT 2010), which I said OK to. However, I have not chosen to revert to older user interface styles, but wanted to use the latest default style, although it requires time to get fully acquainted to it. Could this have had some side effect on tabs, menues and panels?
Resetting AutoCAD LT 2014 to factory default did not fix the Layout Viewports panel problem. This panel does not show and cannot be turned on by right clicking the ribbon and selecting the Show Panels menu.
Well, that made a significant difference - problem solved - thanks!
I relied on the help for creating a (layout) viewport, but the help was incorrect, as it appeared (see below).
Searching the help topics: Create viewport, orCreate layout viewport
gives this result as one of many related:
---------
To Create a New Layout Viewport
A new layout viewport object is available and displays a default view. To adjust the view, double-click within the layout viewport to access model space.
---------
Nothing indicates the Layout Viewport panel is in the Layout tab.
