Topic: Bursting a previously inserted block?

[AVCAD]

Is there away to burst a block right after you insert it. The Select previous command doesn't work very well and usually selects the object you had selected before you inserted the block.

I am sure there is just a function I don't know.

I am on ACAD 2006.

Thanks in advance.

[AVCAD]

just a side question cause I am working on something right now with fields.....

Fieldeval = 31

what is 31?

I know there are

0 - not updated
1 - update on open
2 - update on save
4 - update on plot
8 - update on etransmit
16 - updated on regen

but there is no definition for 31 and thats the default value of that variable

thanks again.

(+ 0 1 2 4 8 16) = ?

[AVCAD]

(+ 0 1 2 4 8 16) = ?

OWNED BY LOGIC....  :ugly:

Use 'Last'

Command: burst
Select objects: L
1 found
Select objects:
/

Just be careful to make sure that that particular object is visible on the screen, otherwise you'll end up with the same problem you had to begin with.

I would use ' (entlast) ' incase the block is off screen, otherwise use what Luis posted.  Just tested, can not be used, as burst is a lisp routine.  I think I wrote a burst routine here somewhere.  So I would go with what Luis said.

Daron beat me to the waring, but I'm still posting!

I must have other kind of powers, because here I can do that.... and works

[AVCAD]

the "last" option might not work always but the entlast would

So can i just write a small lisp to select the last object using entlast, load it through a button and then use the burst command?

I know burst wont work through lisps...not really sure why though but its been like that since forever.

[T.Willey]

You can try the routine here [> LINK <].

You could also insert blocks using the tool palette and set the explode option to yes:

now, I am all confused..... are you guys talking about explode or the burst command?

Should be burst.  Explode won't keep the attribute information, so I would think that explode is a no go.

[AVCAD]

ya no explode.

I actually wish Autodesk would just get rid of that command. But then how would you fix those lovely proxy images with embedded colors from arch desktop....oh wait i know use bylayer instead of embedding colors...oops..i should probably head over to the vent thread...

[Joe Burke]

Of course the downside of relying on burst is it's an ET command. Which may not be loaded or whatever...

It's not difficult to convert attributes to text using explode. That's what I do within the SuperFlatten routine.

[KewlToyZ]

I just use an old copy of burst that automatically selects all, thanks to CAB showing me how to do it.
Placed it into my support directory. The only reason is I can retain some objects like fixtures etc... while removing bound blocks of entire rooms. I just set the number of times to run the routine depnding on how nested the XREF's were before binding when I setup the background files.
