Lisp Mview Program Question

[DDJL]

(defun C:NV () (command "mview" "NE"))

I have this simple lisp program using a new "mview" option which works.
When I add some additional code to change the viewport to a non plotting layer it is never executed.
Does anyone Why that is? And how to fix it. A nesting scheme perhaps.

Set the layer before Mview the set back use (setvar 'clayer "mylayer")

try activex method instead 

 

vla-AddPViewport

vla-put-TwistAngle

vla-put-layer

 

(vlax-dump-object (vlax-ename->vla-object en) t)
