Re: Block-Functions (Select, Explode, etc.)

So Copy+Paste of a blocktablerecord only creates a new instance of this blocktablerecord (called blockreference)?


That means if I paste my beautiful traffic sign 3 times, I have one blocktablerecord and 3 blockreferences on it?


Uuuh, I hope my examiners don't ask bad questions! :smileylol:

That is essentially correct.


I would say, you are not Copy/Pasting a BlockTableRecord.


You start out with a BlockTableRecord, which is essentially data only.  It is not visible on screen, and it is not selectable.


You INSERT (Hence the DXF code "INSERT" that you use in the selection filter) a Reference to that BlockTableRecord, Hence BlockReference.


Then you copy that BlockReference and Paste more BlockReferences, all of which point to the same BlockTableRecord.


If you've only had a short crash course on AutoCAD, then I'm guessing your exam must be programming related not AutoCAD related, right?  In which case I would expect your exam questions to be related more to programming and not AutoCAD.

My examiners don't know anything about AutoCAD, it is the programming part which is important. And because of that, I have to do a lot more exception handling, they understand such things. :smileyvery-happy: work for tomorrow... :smileywink:
