Object Data in the autocad dwg data

Hi Gurus,

This is my first post in this group. I am new to Autocad.

My requirement is , I want to have nongraphic information for each
feature drawn in the dwg file
Say my dwg file has some electrical conductors, so there should be one
table say "Conductor" with fields "Type","material", "length"

Now I should be able to add the data for the static features which
doesnt have this information.
also i should be able to review and add data while digitizing.

Most importantly, no external database(oracle,msaccess) should be
involved, this data model and information should stay with the dwg
file itself.

How to achive these task.Does it need any application development..
Any codes will be really needed.

Also this kind of feature is available in Autocad MAP. But I want it
in Normal Autocad software.

Kindly let me know.

Thanks

Vijay

 

While blocks with attributes are one way to add extra data, I am not
clear about your needs, and if this will be appropriate for you. For
example, say you need to edit the drawing, by doing something like
making the entire circuit board 2' wider. If you attempt to use the
STRETCH command the conductors that span across the board will not
stretch if they are blocks.

Another method is to add "extended entity data". But, this require
some programming with LISP or VBA.

It is also possible to link entities to an external spreadsheet, but
you said you didn't want to use an external file.
