How do i recieve a check from auto insurance companies instead of having them to fix it?

I was just in a car accident and someone hit my car. I need her insurance company to pay for the damage. however I need the check and I don't want to fix the car now. Should I take the car to a body shop and get an estimate for the damage and then send the estimate to the insurance company and ask them for the check? What should I do? please help me.
