Sysvar Changed Reactor and REGEN

[scot-65]

R2024 LT

I am trying to take advantage of CENTERLAYER, DIMLAYER, HPLAYER, and TEXTLAYER as part of our workflow. When the user selects a layer to be current using the toolbar or ribbon control, I am able to

trap this CLAYER change thru the Sysvar Changed Reactor and thaw these associative layers; if frozen.

(setpropertyvalue (tblobjname "layer" (strcat r x)) "IsFrozen" 0)

The issue I am having is these associative layers will become thawed, but do not show.

(redraw) and

(redraw (tblobjname "LAYER" "MYtextlayer")) does not work.

Any ideas how to get these associative layers to display?

How’s about a regen?

Usually a regen is required to show objects on thawed layers. Another workaround I’ve used is to try ssget filter all those objects on those layers and then do a move in place

I have tried

VL-CMDF and

ENTUPD with no success.

@paullimapa 

The sequence is nested inside a reactor event where commands are not allowed.

:vlr-sysvarWillChange does not supply the proposed value, only the variable name itself.

Possibly some sort of vla-get-Layer (not Layers) method with some sort of a vla regen?

I do not want to loop thru a _rather large_ layer list.

Perhaps try vla-regen if this method is allowed

Thanks,

This did the trick.

(vla-Regen (vla-get-ActiveDocument (vlax-get-acad-object)) acActiveViewport) ;-or- acAllViewports

Leaves command line chatter though.

"Regenerating model."

and

"Command:"

Better than not seeing anything…cheers!!
