Hello,
I've created a dynamic profile block for my team and am writing a lisp routine to calculate the elevation along a given route. The width and height for the initial 1:40 - 1:10 profile has been calculated prior to this portion of my routine. I found some sub routines while researching, but can not manage to get the visibility state to change.

My code is as follows and I've attached the block for testing:
(setq rwid 330)
(setq rhte 24)
(command "-insert" "PROFILE_GRID_DYN" pause 1 1 pause)
(setq pent (entlast))
(setq obj (vlax-ename->vla-object pent))
(LM:setdynpropvalue obj "X Distance1" (rtos (+ rwid 20) 2 0))
(LM:setdynpropvalue obj "Y Distance1" (rtos (+ rhte 16) 2 0))
;(LM:setdynpropvalue obj "Visibility1" "ELEV2")
(LM:change_vstate obj "PROFILE_GRID_DYN" "ELEV2")
I'm not sure if its something to do with my code or the block, but any help would be greatly appreciated!
Thanks,
Michael Luckett
