REGEN inside a Reactor

[scot-65]

Trying to design a reactor that will set proper environment based on CTAB name.

One setting is LTSCALE. The command ended event (LAYOUT_CONTROL) will tell

me the tab name but a regen is required after setting LTSCALE.

How do I regenerate the drawing while in a reactor?

If not, then how can I determine the new CTAB name for a/any reactor "will start" event?

(vla-regen (vla-get-activedocument (vlax-get-acad-object)) acActiveViewport)
or
(vla-regen (vla-get-activedocument (vlax-get-acad-object)) acAllViewports)
