Chappyman is correct, the Daytona file is less than ideal, with large features internally to clip to a Mini Z chassis and excessively thick even when scaled down to 1/32. I managed to remove/reduce most of the internal clip features, except for those around the lower sills internally each side due to repeated mesh errors. This was fixed by chopping off both sills up to the seam line then replacing with a much thinner CAD drawn profile matched to the original line and extruded to the right length. The bonnet/hood vent went the same way.
Removing the windows helped shave down the roof pillars, and the underside of the roof was scalloped with a profiled block subtracted, ditto the bonnet/hood with multiple blocks to create lengthwise ribs for strength. The bonnet/hood area has a weak point at the top of the front wheel arch (vertical printing issue of layer separation) so ribbing was the way to go. At the front I scalloped a guide cut out from the front valance using a shallow curve that extended across the valance which also aids printing.
Doing all of this reduced the scaled down shell from 22 grms down to 17grms which includes the body posts and post triangulation I added. The rear section is still too thick but it gives a solid foundation for vertical printing.
Post script to the 1st post is that the file had sections that refuse to allow subtraction i.e. the lower sill clip feature internally but would allow the entire section to be removed. Generally going back and forth to a mesh fixer to correct mesh errors would allow more editing but some sections just wouldn’t play ball. This got to point where I stopped so I could at least print the shell to check the printing to see how viable it is. Now I find I can edit around the lights and managed to remove the glass sufficiently that I can file the rest out to suit.
Cheers
