lisp problem

[Pete]

I have:
(setq ssl (ssget "X" '((0 . "INSERT"))))

I get:
a selection set of all blocks in the drawing.

My problem:
If I put this lisp line after the one above:
(command "explode" "p" "")
I get an error: *Invalid Selection* Expects a point or Last/All/Group

However, if I type the following on the command line after executing the
first lisp line (ssget):
explode <enter> p <enter><enter>
The set of all blocks is exploded.


Why does explode, previous, work on the command line and not in the lisp
code?

[Pete]

What I meant to say is that the explode command has the selection option,
"previous" when used on the command line but when using it in lisp code, it
does not appear to have have that option (along with a few other options)

Anyway, thanks for the help. It works fine. I simplified the loop a bit:

(setq ssl (ssget "X" '((0 . "INSERT"))))
(setq cont 0)
(while (ssname ssl cont)
(command "_explode" (ssname ssl cont))
(setq cont (+ 1 cont))
)

Regards,
Pete

Thanks for the tip. It works fine now after I simplified the code a bit:

(setq ssl (ssget "X" '((0 . "INSERT"))))
(setq cont 0)
(while (ssname ssl cont)
(command "_explode" (ssname ssl cont))
(setq cont (+ 1 cont))
)

What I meant to say is that the explode command has "previous" for selection
option when used on the command line. When explode is used in lisp code,
the previous option does not function( along with a few other options also).

Regards,
Pete

The Previous selection works only for AutoCAD commands; (ssget ...) doesn't
set the previous option. In LISP, you can simply use the variable. For the
EXPLODE command to work on a selection set (multiple objects) in LISP,
however, the System Variable QAFLAGS needs to be set to 2:

(setvar "qaflags" 2)
(setq ssl (ssget "X" '((0 . "INSERT"))))
(command "_.explode" ssl "")

Ok, this is typical Autodesk. Not only is QAFLAGS not documented anywhere
in the help files, it is not even listed when using * in the setvar command.
Yet there it is when I enter it on the command line. Anyone care to offer
an explanation of the function of this mystery variable?

As its name implies (QA = Quality Assurance), I think it was created by
Autodesk's code cutters to provide themselves with some shortcuts that they
were (are) arrogant enough to assume wouldn't be wanted or needed by us
inferior users. There are a number of interesting things that can be done
with various settings of QAFLAGS.

But be careful using the QAFLAGS system variable - if it is not set to 0
it causes some errors.
