Reference area for drag force.
![guillaume_martin](https://cad.onshape.com/images/placeholder-user.png)
Hello,
With my students, I use Simscale.com to do simulations. One of them is to seach for the Drag Coefficient of an OneShape assembly.
It works fine !
But to seach the Drag Force, I need the Reference Area. ( https://en.wikipedia.org/wiki/Drag_coefficient )
The reference Area is the Projected Surface on the plane normal to the wind speed (Is it a good engish sentence
??)
Do you know how to find the Reference Area of an assembly in OneShape ?
