Create true associative dimension with autolisp?

I have created a routine to run a string of linear dimensions through lines
selected via a 'fence-like' method. The dimensions are drawn using the
DIMLINEAR command ala:
(command "dimlinear" pnt1 pnt2 pnt3)

The function works fine except that the resulting dimensions are not
associated to any geometry, even though DIMASSOC is set to 2 and I am
creating the dimensions through the dimlinear command. I have also tried
passing the point to dimlinear command via
(osnap pnt1 "nea") [doesn't help]
and
(nentselp pnt1) [returns "invalid point input"]


Am I doing something wrong? Is it possible to create a true associative
dimension through lisp?

Thanks, Jason

 

You should try our Express Dimensioning 2.01, it is possible to dimension
through lisp.

Why not just use ActiveX to place the dimension, instead of using the
command line, which may cause problems, due to running object snaps, and
incomplete code.

(command "dim" "ver,hor,etc." p1 p2 p3 "" "e")

I see now that if I set osmode to 512 (nearest), then dimlinear will
associate to the geometry. I just can't be for sure which geometry it will
associate with.

I might look into the Active X method for a better solution.
