Tutorial: Animation in 2D AutoCAD

scripting in AutoCAD is very interesting!
Let me show you the basic level scripting that animate the 2D gears.

  1. Step 1:

    First get your gears done in 2D AutoCAD.

  2. Step 2:

    Use "g" in command prompt to create group
    Put each gear in separate group, name each group "1" & "2"

  3. Step 3:

    now open notepad and write down following script
    ============================
    rotate
    g
    1

    (x,y)
    1
    rotate
    g
    2

    (p,q)
    -1
    rscript
    ===================================

    NOTE: here, we are ordering our beloved autocad to rotate the group 1 with 1 speed about (x,y) axis(co-ordinates).... same withe the group 2, rotate the group 2 with -1 speed about (p,q) axis(co-ordinates)

    Use "ID" command to locate the center-point of gear.

  4. Step 4:

    now save your notepad file with [.scr] extension
    your file name can be any thing.
    mine is "gear.scr"

  5. Step 5:

    now type "scr" in your autocad command prompt, hit enter, browse to the "XYZ.scr" file you just created.. and you've done!!!!
