Help subtracting Mesh from Solid

[gobluejd]

I have half a car body and trying to Boolean Subtract from a solid (rectangle).  I want to take the car and subtract it from the rectangle, leaving just the rectangle with the body subtracted.  I have tried several things including using mesh mixer but it is limited to 5000 triangles and this has over 500,000.  I am not sure what the next step is.

Can anyone point me in the right direction?  I have attached a screen cast of the parts.

For some reason the screenshot was not appearing in the "Insert Screencast" so here is link....

Hi Jeff,

If you are a subscriber, you can go to the following link to download Mesh Enabler. This will help you convert Mesh to Composite Surface. Then you can stitch it into a surface body and cut the solid.

One thing you might consider is that the triangular mesh you are seeing in Inventor precisely depicts how the model looks like. Some software rounding the edges and faces creates an illusion that the model looks smooth. The facets are there. If you use it to cut, the facets will be on the solid body too.

Many thanks!

Thanks.  I did in fact use that (I called is mesh mixer) and it will not do it due to the amount of triangular surfaces (maxes at 5k, I had 500k).  I will just try and do in StarCCM CFD software....
