+--- Thread: [LDView] Bad vertex sequence in BFC-enabled quad. (/thread-24678.html)
Bad vertex sequence in BFC-enabled quad. - Michael Horvath - 2021-06-11
How do I fix a file with errors like this? Do I simply copy and paste 'New Quad' over 'Original Quad' in the part file?
Error: Bad vertex sequence in BFC-enabled quad.

(Note: disabling BFC for this quad.)
Original Quad: <10 0 4.14> <20 32 8.28> <10 0 -4.14> <20 32 -8.28>
New Quad: <10 0 4.14> <20 32 8.28> <20 32 -8.28> <10 0 -4.14>

Just run the part through an error checker like DATHeader, LDPE, or LDDP. Have it fix the error and then, if needed, flip the quad to the correct winding so the green face is out.

In addition to what Orion said, you can use the points in the order of "New Quad". However, you can't just copy and paste, because you have to remove the angle brackets first. In this case, LDView is treating the quad as if it looked like this in the file:
4 16 10 0 4.14 20 32 8.28 20 32 -8.28 10 0 -4.14
Also as Orion mentioned, you can reverse the order of the points if the quad shows up as red instead of green in BFC test mode in LDView.

Okay, thanks!
