inserting Blocks with Attributes
Let's insert these blocks (which are now grid symbols) at the endpoints of the
gridlines. As you insert them, you'll assign them the appropriate letter or num-
ber, but first you'll make sure that AutoCAD uses a dialog box to prompt for the

the
ATTDIA
variable

INSERT

at the command
prompt, for attribute

Be sure the Specify On-Screen box is checked for Insertion Point but
not for Scale and Rotation, so that those values remain constant among
the blocks and you're not prompted to change them. Click OK.
