Hi,

 

How to calculate car's frontal area in Hypermesh?

 

I'm tried project the whole car surfaces into a plane. However, those surface intersect with each other which cause calculation of area does not true.

 

Thank you

    After projecting, I think you have to look for external border in order to compute the projected area, right?

    Yes, I need to have external border to compute projected area.

     

    Tried manually by check intersection but not successful. Any idea?

    Here's my test.

    From projected lines, you can found external boundary and make a surface in order to compute the area. I don't another way to do that.
