Smart Block to regular block

Ken.castillo — Wed, 07 Aug 2019 19:40:04 GMT

As we are migrating to AutoCAD Electric one of our clients has an Issue. I know that Special Explode will convert all to lines etc. Our client wishes for the blocks to remain however just not electrical. Blocks with attributes, just not intelligence.

Blocks with attributes are intelligent. Not sure what you are wanting here.

can Electrical drawing can be opened in regular autocad?

Well, it's the attributes that make the blocks intelligent, so this probably isn't possible.

Or, more accurately, it's the attributes in the blocks that allow ACADE to execute its commands. The intelligence is actually in the command structure, but we still often refer to the blocks as if they are what's 'smart'. Put those blocks in any other software and they're as dumb as a box of rocks. But, the same can be said for a block in this software, if it doesn't have any (or the correct) attributes.

If you take out the attributes of an ACADE block, you're also removing all of its annotation. Cross references, tags, pin numbers, etc are all held in attributes.

That being said:

If your clients aren't running ACADE, then they won't be able to use the attributes anyway - so might as well leave them in.

And if your clients ARE using ACADE, then taking the attributes out of the blocks would totally undermine the software's ability to use them. Essentially, you'd be breaking the blocks so that they no longer work. Which means you wouldn't be able to do anything with them either, for instance if the client wanted the drawings edited in the future.

If they're adamant that you supply them with drawings where the blocks aren't intelligent, but are still blocks, then I suppose you could use Special Explode to remove the unused attributes, and then re-block each symbol with a new name. The amount of CAD time this would take could very quickly cost the client more than what it did to create the drawings to begin with.

It should be noted that any block built specifically for use within ACADE should function just fine in non-Electrical AutoCAD software. Meaning, you can take any one of ACADE's symbols into Mechanical, or regular vanilla ACAD, and use them as a block. You won't need a proxy handler or anything like that.

Yes I agree, however when working with GLOBAL mega oil and gas corps that have drawings that are over 60 years old, they are very reluctant to change. Unfortunately it is mostly the US based companies that are like that.

Technically I guess you could open the blocks in block editor and rename all the attributes. That way it would technically meet the criteria, in that the block would still have attributes but it would not be intelligent in the sense that ACADE would not know what to do with the attribute data. Though why they would want this is beyond me.

Also doing this to every single block is not going to be fun.

As Jim alluded to ACADE produces 100% standard AutoCAD DWG drawings. You can open these in AutoCAD, AutoCAD LT, etc. You could, for example, open an ACADE block in the AutoCAD LT attribute editor and see it has an attribute called 'ASSYCODE' and its value is 'xyz' like any other kind of attribute. The difference between ACADE and AutoCAD vanilla is ACADE knows to look up its database for parts with corresponding 'ASSEMBLYLIST' values whereas AutoCAD will just treat it as any other attribute.

You could even edit attribute values, move blocks, redraw lines etc. in regular AutoCAD but it is very likely to cause project issues if that drawing is later used again in ACADE.

Just for fun, I made a little VBA macro, that stupidifies the drawings. It renames all layers/blocks/attributes.

Can be run in a script to apply to many drawings.

See attached drawing for example.

@rhesusminus Any advice on how to use this in a script? I have some work I need to send to a competitor and we don't want to lose any IP. Many thanks in advance.

This works in a script.
