Sysvar "CETRANSPARENCY" does not set to "BYLAYER"with setvar

[Anonymous]

Hello all,

For AutoCAD 2012, I've attempted to use the following expression in a Lisp program:

(setvar  "CETRANSPARENCY"  "BYLAYER")

It returned the message: ; error: AutoCAD variable setting rejected: "CETRANSPARENCY" "BYLAYER"

This feels kind of strange, because I can set CETRANSPARENCY to BYLAYER by entering both words at the command line prompt. Is CETRANSPARENCY only valid as a command, perhaps?

With friendly greetings, M. Moolhuysen.

Hi,

Autodesk did a little bit mix and so setting the variable CETRANSPARENCY by a string-value ("BYLAYER") is not allowed in this case.

Instead you can do:

(setvar "CETRANSPARENCY" -1)

...and -2 stands for "BYBLOCK" 😉

 HTH, - alfred -

Ah, I did try to set it to 256, as I remember that could mean "BYLAYER" in the old days....

256 doesn't work here, but -1 does. Much better, thank you. Unfortunately this bit of information is missing in the Help.
