Cannonscale setvar

[whitney_jeff]

Accidentaly used the wrong name for my original post

I have a setup lisp routine that creates a scale factor - I would like to pass that on to cannoscale, but cannoscale seems to only recognize architectural formats such as 1/8" = 1'-0".

The test expression (if (=  sf 96) would be the start of the expression (sf is my scale factor) - but I cannot figure out how to pass the arch scale 1/8" = 1'-0" on to cannoscale in a setvar statement.

I tried (setvar "cannoscale '1/8"=1'-0") but it seems the second quote mark messes it up.  How can I get around this?

Many thanks!

(setvar "cannoscale '1/8\"=1'-0")

put a backslash to escape the quote.

[whitney_jeff]

returns "too many arguments"

I tried (setvar "cannoscale" '1/8\"=1'-0")

(setvar "cannoscale" '1/8\"=1'-0")

(setvar "cannoscale '1/8"=1\'-0")

and other variations

Hi Jeff,

try

(setvar 'CANNOSCALE "1/8\" = 1'-0\"")

there are spaces and a last "

Hope this helps,
Henrique

There is no joy in Muddville 

The leading single quote I have (') is equal to (quote), but the second single quote used as the foot mark (1') as well as all the double (") quotes (inch marks) really seems to mess everything up.  I wonder if I would be better off doing a setq for the scale and then using something like (setq 1-8 "1/8\"=1\'-0\"") and then (setvar "cannonscale" 1-8)?

Sorry, I didn't look at your code closely enough.  setvar takes 2 arguments, the variable name and the value.  There are two possible ways to enter the variable name, 1)as a double quoted string, or 2) as a single quoted variable

(setvar 'cannoscale "1/8\" = 1'-0\"")

or

(setvar "cannoscale" "1/8\" = 1'-0\"")

The value cannot begin with a single quote because cannoscale must have a string.  In addition, the name must be exact with spaces.

Before coding, I suggest using getvar as in

(getvar "cannoscale")

"1/8\" = 1'-0\""

It will show you exactly what to type if the annotation scale is already set.

DB - that worked.  I swear I tried that combination and it bombed.  AutoLISP - go figure!

Thanks for your help and patience!
