To check the BFC'ness of your file, use L3Lab. While viewing the file,
select the Test | mytest6 menu option. This will color-code all the
rendered surfaces. Green is the front/outside of correctly wound surfaces,
Red is the back/inside, and blue is used for quads that aren't wound
correctly (ie, they're specified like 1324 instead of 1234 or 4321).
Blue is also used for subfiles that aren't BFC compliant. If you use the
standard p-files, you'll see a lot of blue.
A part which is completely, correctly BFC-compliant would appear all green.
LDraw Add-on has a function in it text Editor to reverse the winding of
polygons. You can get LDAO from its long-standing, temporary location at
