(URL) Primitives such as partial cylinders or spheres have conditional lines on edge. For cylinders, these integrated conditional lines are expected to match a tangent plane, for spheres they match a joining cylinder. If you try to join something (...)

(...) Hmmm, it seems to me that any algorithm that can find the missing Type 5 lines (in order to create the dummy entries) should be able to find *all* of the Type 5 lines. Some missing lines is just a special case of all missing. So just include (...) (14 years ago, 23-Sep-10, to lugnet.cad.dev.org.ldraw)

(...) Actually, no. That is indeed a long-term goal, but it is hampered by two things. First of all, it's a lot of work. Secondly, the current algorithm is actually useful to part authors, since it can visually highlight missing conditional lines. (...) (14 years ago, 23-Sep-10, to lugnet.cad.dev.org.ldraw)

(...) Unfortunately it messes up unless you inlude FTX line breaks, or fixed code box characters (pipe). Unfortunately, both make it harder for people using email or newsreaders, so probably best to do it as you did, browsers can just click "View (...)

(...) Sorry for that ;o) But (fortunately) here are very few twisted surfaces in LEGO pieces, so I don't think my tool has created too much havoc... (...) Problem is that at this low level I have almost no information about the intended geometry - I (...) (14 years ago, 22-Sep-10, to lugnet.cad.dev.org.ldraw)

Meshlab is more austere and lacks documentation, but the few needed functions can be conquered without (...) (14 years ago, 22-Sep-10, to lugnet.cad.dat.parts)

(...) reads the primitives correctly. What I meant about bad lines was that I noticed your tool does some checking for spurious lines; that must just be for lines between coplanar surfaces.

(...) Very interesting! (URL) I am not so much comvinced by the improvement for flat shading. Looks like we trade triangular artefacts in one direction with artefacts in the other one. But it drastically improves the very ugly condlines artefacts! (...) (14 years ago, 22-Sep-10, to lugnet.cad.dat.parts, FTX)

(...) Not sure what you mean - it doesn't check if a line has its ends properly ending on a surface vertex. (loosely related) I have a pending update for edger2 that check if the angle of existing condlines matches angle between surfaces. If the (...) (14 years ago, 22-Sep-10, to lugnet.cad.dat.parts)

Did anybody ever did actually fix the parts though? I (...) (14 years ago, 22-Sep-10, to lugnet.cad.dev.org.ldraw)
