Rotate high amount of polygon vector data

Question

Hi all

I have problem when I want to rotate my vector data (rotate to 14 degree from azimuth). I have polygon with the total amount around 102,000 (each polygon have size about 9 m x 15 m). I have tried to rotate all the polygon by using Rotate Tools but it seems like my laptop (i5 with 8GB RAM) cannot handle that operation.

Even today, I let the operation continue for 5 hours and not finished yet! I have tried this up to 4 times. I also have tried to use rotate manually by using mouse or by input the rotate degree (by pressing 'A' and input the degree number).

Is there any way to solve my problem?

welll if you are slightly adept at handling code, you can use the example in here

rotation is easy during initial creation

Finally, I can solve my problem

I used extension geowizard from ian-ko (http://www.ian-ko.com​). His tool allow us to rotate feature with custom azimuth number based on our need.

Cheers..
