parameterization in autocad 2002 drawings

[sfhaider]

i have a 2-d drawing (not to scale) in autocad 2002. I want to write a program to in lisp , visual basic or c etc to change my dimensions to have different values as required and turn on/off few desired layers , save it with a name . How can this be done. Any ideas. thanks all

Are you experenced in LISP VBA ???

The thing you woud like to do cannot be done automaticly ...
For example ..
A line is 500 in you're drawing, but you want it to be dimensioned as 600.
You ALWAYS have to enter the value 600 manually, so i dont think you can make it faster by creating a LISP or VBA file for it.

but first of all, why in godsake you make drawing that doesnt have the right scale ?? Start making drawings that are 1:1 scale.
Drawings with no scale are really bad.

But if you want to change a dimension:

command line: DIM <enter>
command line: NEWTEXT <enter>
command line: "Youre value" <enter>
Select the dimension ...

Thanks for the reply. I was wondering if i can read the DXF file and change the values thru a program, not manually
I am ok in LISP. and can do in Visual Basic
The drawing i got is not to be scaled. Makes no sense in scaling the drawing.
Anyway whats the input on how to use a scaled drawing and be able to do what i am trying to do.
Thanks again
