You could possibley make it a dynamic block with a point parameter.  Then in the block properties you can make it non explodable.

[SomeCallMeDave]

If you are using 2007 or above  (I'm not sure which other versions it works with), you can set the 280 value of the block table record to control explodibility

Code: [Select]

(defun dkb_setexplode(pBlockName pExplodableIfOne / a b c d e ); second argument 0=non-explodable 1=exploxable
   (setq a (tblobjname "block" pBlockName)
         b (entget a)
         c (cdr (assoc 330 b))
         d (entget c)
         e (subst (cons 280 pExplodableIfOne) (assoc 280 d) d)
   );setq
   (entmod e)
   (prin1)
)


Use at your own risk

Thank you very much , SomeCallMeDave ! you are right! It's simple,I agree:-)

However if you saveas dxf version 12 and the reinsert the saved block, that will strip away the non explodability.

We use the free deter.vlx routine from dotsoft.com. (which will stop most users from exploding the block)

Not that I am against any great routine or code by some masters - outside the swamp, and I know their solutions are in most cases valid.

But, I guess or think that we [as swampers] need to promote what we do here and provide also for free - that, in some way will encourage to continue providing better solutions or updating what it is available here in our site - ...

And again, I am not against any other outside solution at all.

Just my two pesos....

also, promoting sites or people for free, that does not provide any help here... I will prefer to avoid that.... just my poor opinion....

just my another two pesos....
