need an example for insert xdata with xdata (-3 groupp)
there's nothing in ourbase.c
thanks in advance,
ef

sorry, 'Insert xdata with sds..'
ef

this works...

struct sds_resbuf *rb = NULL;

sds_regapp("TESTE");

rb = sds_buildlist(RTLB,
RTSTR, "(ENTMAKE (LIST (CONS 0 \"LINE\")",
RTSTR, "(CONS 10 (LIST 50.0 0.0 0.0))",
RTSTR, "(CONS 11 (LIST 100.0 0.0 0.0))",
RTSTR, "(LIST -3 (LIST \"TESTE\" (CONS 1040 1.0)))))",
RTLE,
0);

sds_retlist(rb);
sds_cmd(rb);
sds_relrb(rb);

But need other ways (in c, not c++)

ef

Both C and C++ use the same method of attaching Xdata to an object.
What you’re doing is sending lisp string to be evaluated.
You can send the DXF values directly.

Here is a sample, but provides no error checking.

thank you very much, Daniel.
it works perfectly...

;; this is the function where xdata was needed
;; draw 2 or 3 lines (pipe + center line)
;; it uses xdata for inserting components after...
