How to arrive Centre of gravity point in overall vehicle (Tractor/Car) layout.

Available data are

1. Wheel base/Wheel Track

2. Tyre Details

3. Over all vehicle layout cad assembly/parts (In virtual only. Not physical)

4. Overall weight of the vehicle

Front and Rear reactions are not available.

I am using CREO-4 parametric. 

Kindly suggest to find the COG point in virtual layout assembly.

Go to the Analysis tab, then mass properties, then click the preview button.

It is correct. But over all assembly containing 1000 parts is difficult to find. It shows few errors.

Anyway any theoretical calculation method is available?

If you know the center of gravity of each component and the weight of each component, you can sum the moments to calculate the center of gravity. Theoretically.

If your models are correct, weights and CG, you can use Creo.

You can assign mass properties to a part or assembly. I don't use that method, you'll have to learn those details.
