This is quite lengthy to explain, but anyway, here it goes.
let say you wanna create a simple title block with only two attributes, ie.drawing number and drawing name. (I assume you're using version 2004 and above.)
1) use command ATTDEF, key in "drawing number" for TAG, "drawing number" for PROMT (it's a good practice to use the same description for these two) and "XXXXXXXX" for VALUE (assuming your drawing number convention is of 8-digits format).
2) check the font size, adjust it necessarily.
3) press OK button.
4) move the cursor to the location you wanna place the TAG (the TAG should appear as "drawing number".
5) use command ATTDEF, key in "drawing name" for TAG, "drawing name" for PROMT (it's a good practice to use the same description for these two) and "ABCDEFG" for VALUE (assuming that's your drawing name convention).
6) check the font size, adjust it necessarily.
7) press OK button.
8) move the cursor to the location you wanna place the TAG (the TAG should appear as "drawing name".
9) block the two TAGs
10) you'll notice the two TAGs will change to "XXXXXXXX" and "ABCDEFG" respectively (these are the default VALUE you've just typed in!)
11) use command DDATTE, click on the block and a data entry sub-window will be prompted.
That's all, I guess. Good luck
Best regards,
