Problem with 15068.dat : Slope Brick Curved 2 x 2 x 0.667
#1
Hello,I was repairing my crappy 15068px0  when I noticed that there are gaps in this part.

The subfiles don't match at the vertices 20 -4 -20, -20 -4 -20, -20 -16 20 and 20 -16 20 (aka the top corners) the 48\1-8cyli.dat don't match the s01, and inside the s01, the 48\1-8chrd.dat don't match the top corner either.

1 1 -20 24.9719 20 0 1 0 -40.97 0 0 0 0 -56.57 48\1-8chrd.dat
1 2 20 25 20 0 -1 0 -40.97 0 0 0 0 -56.57 48\1-8chrd.dat
1 4 20 24.972 20 0 -40 0 -28.9719 0 -28.9719 -40 0 40 48\1-8cyli.dat

I didn't check all the printed parts, but the problem is present on p01 for instance.

Should this part been reworked or should it be left like that ?

Yes, I saw the same issue in 93273, and repaired the subfile. I think the same issue is present in many of the curved bricks, in this family of parts.
I seee the same bad vertices in your example.

Thank you. The following code seems ok, but when I tried to round the values to 4 decimal places, it didn't work anymore. Is it ok to keep such decimal places  ?

I used this in 93273:
1 16 -10 24.9719 0 0 1 0 -28.9719 0 -28.9719 40 0 -40 48\1-8chrd.dat

and the arch 92950 have been corrected recently, and is using this:
1 16 0 48.972 -10 -40 0 40 -28.9719 0 -28.9719 0 4 0 48\1-4cylo.dat

I don't know who made the initial calculations, or why the first point is on the front instead of on the top.
I think we should use the same values here.

Code:
1 12 -19 24.972 20 0 1 0 -28.9719 0 -28.9719 -40 0 40 48\1-8edge.dat
1 12 21 24.972 20 0 1 0 -28.9719 0 -28.9719 -40 0 40 48\1-8edge.dat
1 12 -19 24.972 20 0 1 0 -28.9719 0 -28.9719 -40 0 40 48\1-8chrd.dat
1 12 21 24.972 20 0 -1 0 -28.9719 0 -28.9719 -40 0 40 48\1-8chrd.dat

It looks like "20 24.972 20" gives a better precision than "20 24.9719 20".

A corrected subfile is now on the Part Tracker.

Nice, I'm going to check if it fits my file.
