Visual LISP, AutoLISP and General Customization

[#1]

AutoLISP Experience: Minimal

Background: Someone exploded an attribute block and copied it hundreds of times throughout a project, each time changing the Attribute Tag to match the Value they expected to appear in their drawing.  The drawing must be xrefed, so the attribute definitions do not appear.

(There is only 1 attribute in the block.)

Proposed Solutions:

1:AutoLISP routine which copies Tag data from Attribute Definition into Value of Attribute Block:

Prompt-Select Attribute Definition

Copy Tag data

Prompt-Select Attribute Block

Paste data into Value

(Allow repeat to speed workflow)(*PREFERRED*)

2:AutoLISP routine which copies Tag data from Attribute Definition into Default Value and creates a new Block:

Prompt-Select Attribute Definition

Copy Tag data

Paste data into Default Value

Create New Block

(Select Multiple Objects)(Creates tons of new blocks which are messy)

Thanks so much, this worked great!

You probably cut our repair time down to a quarter of what it would have been or better.

Exactly what we were looking for.
