Attribute Tag and Values
Attribute Tag and Values
(OP)
I have been using a program (DWG Miner from Skysof) that can read the attributes tags and values from DWG files.
In this case Piping and Instrument diagrams.
What I have found is that there seem to be additional attributes that are not visible on the diagrams, and some of which have negative X or Y locations.
Is it possible that for example copying one diagram to make another different one could leave behind old and dead Attributes?

These are examples of the Atttribute Tags
TNAME , TNO , APPLIC, FSAFE, IOTYPE, RANGE
Are these standard to AutoCAD or just values someone has entered, or could they be generated by some software?
Thanks

Whether the attribute should be visible is again down to how it was set up in the first place. This (to my knowledge) can only be assessed when a block is exploded.

Are these Dynamic Blocks? That could explain some of the invisible attributes.

I don't know what Dynamic Blocks are or how to find out. By the way the files are 10 to 15 years old.

Francist - Given the age of the files, that would not be the cause of the invisible attributes. Dynamic blocks were introduced in AutoCAD 2008 I believe.
I would submit then that the invisible attributes and their purpose are known only to the original author(s).
You should be able to edit the attributes (attedit) to see how they were defined.
