Gap and primitive.

[Bertrand Lequy]

Hi

I would replace the

1 2 2.5 148 5.25 1.848 0 -0.765 0 -4 0 0.765 0 1.848 3-8cyli.dat

with

1 2 2.5 148 5.25 0 0 -2 0 -4 0 2 0 0 3-16cyli.dat
1 2 2.5 148 5.25 0 0 2 0 -4 0 2 0 0 3-16cyli.dat

so you avoid a 67.5 deg rotated part (3-8clyi) touching a non-rotated one (ndis)

I cannot see the issue with the inlining, I am using LDPE, though.

I would then move the two quads
4 16 0.649 148 6 0.5 148 6 0.5 144 6 0.649 144 6
4 16 4.351 148 6 4.5 148 6 4.5 144 6 4.351 144 6


to touch the 3-16 ndis
4 16 .6523477 148 6.0157893 .5 148 6.0154 .5 144 6.0154 .6522 144 6.0154
4 16 4.348 148 6.015 4.5 148 6.0154 4.5 144 6.0154 4.348 144 6.015

I  do not know where in the part (WHAT a part...) this sits, but the 0.0154 LDU should be possile to accommodate without any visual imparment, if you need them to be at Z=6 then I would even consider the quads like this

4 16 .6523477 148 6.0157893 .5 148 6 .5 144 6 .6522 144 6.0154
4 16 4.348 148 6.015 4.5 148 6 4.5 144 6 4.348 144 6.015

Touching the 3-8ndis at 6.0154 and the other side at 6

Thank you for your help, replacing the 3-8cyli by 2 3-16cyli helped  a lot. I check all the coordinates (some fourth decimal were incorect) and it seems to be ok for now.
