Surface elevation -- Jeff Michler et al

[Anonymous]

LDT2004
The attached is a boiled-down and augmented version of Jeff's original. Works fine, but
does damage to the stability of Acad; after using it and running a few commands, the
program terminates abruptly; no invitation to save, just wham! I have an ungrounded
suspicion that there is a conflict with autosave but who knows? Saving immediately after
use is a good idea but does not forestall ultimate doom. Maybe I cut out some important
stuff? Maybe repeated invocation of (vlax-get-acad-object) and the other starter items
confuses the program?

When using VLA-OBJECTS that are not native to Autocad they usually need to
be released or these type of problems arise.

I just ran this about 30 times, sometimes by cancelling, others by erroring
(i don't have all of the subroutines....), without having a melt down occur.

I've heard that the method I use to set the AeccApplication fails in
LDT2008. I'll post an update once I have it installed to verify.

;elev. point on surface and optional mark.
;thanks, Jeff Mishler.

Thank you, sir. I will try it. If it fails I will know that my third suspicion was valid:
my computer hates me.

Had I known that someone was actually going to run the routine I would have included
#mktext and #mkpoint.
