Cowski, the car was built for a video games using polygons. The only method I have found to get it into NX was through the DXF option.

Update: The thicken surface feature will work if i apply edge blends to each edge in the faceted body, creating a "smooth flow" from one face to the next. I think what is happening is it attempts to thicken one face and it collides with the next face over, and creates discontinuities in the...

With the failure to thicken the sheet, I get the general error: Unable to apply thicken. I did a test case, one with a sinusoidal sweep that resulted in a 3-dimensional curve, and the other with a bunch of triangles (much like my geometry of the car) that were turned into sheets, sewed, and...

I did a test on a layer that had passed the all the areas of the geometry analysis, and I am still unable to have the sheet/surface split the block.

Self intersecting face detected. How am I supposed to find it with 16000 faces in the body???

I am attempting to run a CFD analysis on a car. I have been able to convert the 3ds Max file into a *.dxf, which imports to NX3 as a faceted body. I then "sewed" the multiple faces together, extracted geometry, and got a surface/sheet, which imports to Fluent. The car's body is essentially one...
