- Add BFC CERTIFY CCW per the header spec
- Open the part in LDView
- In Preferences -> BFC, check the "green front faces" and "red back faces" options and click apply
- Look for any red
- If it's a tri/quad, reverse the winding
- If it's flat primitive, flip it 180
- If it's a non-flat primitive, put BFC INVERTNEXT before it
- Continue until there is no red
If after step 1 the part is all (or mostly) red, you might want to change the BFC CERTIFY CCW to BFC CERTIFY CW instead of having to edit everything. Also, if you enable blue neutral faces in LDView, faces that aren't being culled will show in blue. There are valid reasons for blue faces, but they are relatively rare.
