This car breaks down into many more pieces in Truespace(about 10 thats how it was posted by keith )
and can be flipped each one that way yes....
but I rather have an option to flip all at once.
I have a few Moi 3d files with dozens of seperate parts all stored in the file and only some are flipped.
The flip tool on each of them would be to difficult as some parts are just small screws...
The boolean subtraction did well on the whole model in one go.
For some reason i did not look into the detail yet the parts did
not all join easily... but I must look at that closer.....
Thanks
Peter
