Which viewport is activated when typing MSPACE?

[Kh.mbkh]

I'm using a loop to repeatedly do these actions while building various viewports:

(setq LayoutName (last (GetLayoutOrdered)))   ; Get last Layout
(setvar 'ctab LayoutName)  
(command "._pspace" "._-vports" Pi Pf )
(setq vp (entlast)) 
(command "._Mspace" )
(command "_.ZOOM" "w" PBG PHD)
(command "._pspace" ) 

Variables Pi, Pf, PBG and PHD change during the REPEAT loop.

My issue was with the "Mspace" command; it did not select the last viewport I just created. It remembered other previous viewports.

So my question is: how to specify the viewport that will be activated with "Mspace"?

You can set the variable entvp as the ename of the desired Vport

and follow this that ensure you go to mspace and set selected vport as active 

(setq MsVp (vlax-ename->vla-object entvp))
(vla-put-mspace acadDoc :vlax-true)
(vla-put-activepviewport acadDoc MsVp)

Hi there

alternatively you can activate the specific viewport with this code:

(setq vpnum (cdr (assoc 69 (entget vprt_ename) ) ) ) )
(vl-cmdf "_.mspace")
(setvar "CVPORT" vpnum)

where vprt_ename variable ist that viewport ename

You've got the points you used to create the viewport, use one of those in an ssget filter like '((0 . "VIEWPORT")) to select then activate it.

Trying to find it had similar problem picking correct viewport, when you make the viewports you can get then back as a VL variable and set current using a VL-item with correct number. Easy to work out how many. Will keep looking. I think removed from problem that I was trying to solve why I can not find.
