Hello,
Anyone could help me in creating wobble geometry in 2D view. similar to below pic.

do you need to do it once, or many times? It is basically a point on a circle which is rotated as it is moved along.

If you need to do it only once (or few times), you can do it as follows:

1. draw a dot at the start point, and select it
2. choose the 'Move and Rotate' tool from the Modify menu
3. The Reference point is the centre of the circle, or in your case it is half the amplitude to the right of your dot
4. The Target point is a step in the direction along your scanning length
5. In 'Move and Rotate Options' you choose 'Multiple Copies' and something like a couple of hundred, and and angle of something like 10 degrees

Then you get an image like this

and if you like the parameters you can join the dots manually with the spline tool, though the parameters might need a bit of calculation to get what you want.

If you need to do this more purposefully, you would have to write a script; this is probably not that difficult (probably just modify the LineBoxJoint script)
