Model Space / Paperspace tabs...

I created a customized workspace in Civil3D using the Task-Based Geospatial workspace but for some reason my model space and paper space tabs have gone missing?

they are also missing in the Tool-Based and Task-Based Geospatial workspaces.

I would like to have access to these with out having to swith to different workspaces. How can i do this??

If i can not what is the reasoning behind this.

Make sure the check box is selected in the Options window (OP) on the Display tab (bottom left in the layout elements).

For fun :

(defun c:LayoutTabs  ()
 (vl-load-com)
 (princ "\rLAYOUTTABS: ")
 ((lambda (oDisplay)
    (if (= :vlax-false (vla-get-displaylayouttabs oDisplay))
      (progn (vla-put-displaylayouttabs oDisplay :vlax-true)
             (princ "ON "))
      (progn (vla-put-displaylayouttabs oDisplay :vlax-false)
             (princ "OFF "))))
   (vla-get-display (vla-get-preferences (vlax-get-acad-object))))
 (princ))

Brilliant...

thank you kindly gents.

the code is beyond me. But i will trust that it works the same? What would i do just copy and paste that into the command line?

The code posted above is basically a toggle, which looks for the current state (i.e., On, or Off), then sets the opposite current.

To test this, simply copy and paste the code at the command line, and hit enter, which will load the function into the Active drawing's memory. Then invoke the command typing "LayoutTabs" (without the quotes) at the command line, and hit enter. Lemon Squeezy.

There are many ways of adding LISP routines to your setup, Lee's been kind enough to write some great tutorials so I don't have to. LoL
