Parameters Dynamic Blocks

[Lupo76]

Hello everyone,
I'm using the attached lisp to change the parameters of adynamic block.
In particular, I use the function chgdynprop

(defun c: test ()
   (setq oggfreccia (car (entsel)))
   (chgdynprop (Vlax-ename-> vla-object oggfreccia) "Distanze1"300.0)
)

The lisp function works properly, because if I select the block from the bar I can see that property Distanze1 = 300.0

Unfortunately, however, the graphics of the block is not updated.
Do you have any advice?
Thanks in advance

Excuse me,

the code works correctly.

The problem was in the dynamic block 😉
