Topic: ( acad 2006 vanilla ) dynamic block & hatch

[Mark]

For some reason, in this one particular drawing, when ever I flip the block the solid hatch that's part of it stays behind. I've tried everything I can think of! *baffled*

[MP]

Dump the hatch object so we can see its data?

Code: [Select]

(   (lambda ( / ename )
        (if (setq ename (car (nentsel)))
            (progn
                (vlax-dump-object (vlax-ename->vla-object ename))
                (mapcar 'print (entget ename '("*")))
            )
        )
        (princ)
    )
)

Could you post a drawing of the block itself?

The one thing I've noticed with hatch patterns in DBs is that AutoCAD sometimes needs to be reminded that something has changed.  Does it look correct if you do a REGEN after flipping it?  I have to do that sometimes even with '08.

Could you post a drawing of the block itself?

I could Daron but it works fine in every other drawing.

[Mark]

Does it look correct if you do a REGEN after flipping it?

Nope! That works in other drawings, just not this one.

[MP]

I could Daron but it works fine in every other drawing.

So don't post the other drawings.

fine .... *sigh*

[Mark]

After deleting everything and purging the .dwg the block works fine in said drawing so .....

Mark,

Your stretch action makes the block look funky in 2008. I don't have any problem with the mirror?

If I open the block in the block editor then close and save, the hatch in the block updates and looks correct. But it's only good for one time.

Thanks Ron.

[Mark]

Attached is the .dwg that's giving me the problems. I've stripped most everthing out of it and the block still does not work correctly.

[ronjonp]

That is strange...it breaks here too. I have still not figured out why my block completely loses its dynamic properties in certain drawings. Me thinks Autodesk needs a little bit more time developing them.
