Redefine Blocks From Webpage URL

Not done much AutoCAD for a while, but have a need to come back ot it now. Does anyone know if it's possible to redefine a block in a drawing with one from a webpage?

For example it's possible to insert the file that is here: http://www.arcat.com/details/mielepro/11600108.dwg using the -INSERT command:

Command: -insert

Enter block name or [?] : http://www.arcat.com/details/mielepro/11600108.dwg

But if I try redefining an existing block in a drawing, I get an 'invalid filename' error:

Command: -INSERT

Enter block name or [?] : Sink01=http://www.arcat.com/details/mielepro/11600108.dwg

Block "Sink01" already exists. Redefine it? [Yes/No] : y

*Invalid*

Any help much appreciated.

My guess is that the block was created with a newer version of AutoCAD than the one you are using.

Can you open the block file?

Yes. This works fine:

Command: -insert

Enter block name or [?] : http://www.arcat.com/details/mielepro/11600108.dwg

Can you let me know if this works for you...

Command: -INSERT

Enter block name or [?] : NameOfAnExistingBLockInCurrentDrawing=http://www.arcat.com/details/mielepro/11600108.dwg

Block "NameOfAnExistingBLockInCurrentDrawing" already exists. Redefine it? [Yes/No] : y

Sorry, but I misunderstood your OP. I won't try what you are suggesting. I don't know if it is even possible to insert a block using a link. If it is, I would need to be absolutely certain the block is safe.

After some more digging I reckon I'll have to download the file first using vla-GetRemoteFile: http://forums.augi.com/archive/index.php/t-127623.html and then insert it.

Download and open the drawing in your AutoCAD;

Open the drawing you are wanting to insert the block into;

Open DESIGN CENTER;

In Design Center open the downloaded drawing and click on BLOCKS;

Find the block you want and drag it into the target drawing (the drawing you want to use it in);

You can then modify and wblock a new rendition of what you desire in this block;

Name it something different, then purge the original block out of the drawing.
