 | | Weird Logo Issue at L3P Quality Level 3 —Richard Marchetti
|
| | | Hey Y'all: If you render the element 4869.dat with L3PAO quality level 3, as far as I can see you get the logo reversed. Other elements render fine. See: (URL) the aforementioned jet engine insert rendered next to a 2x2 round brick. The logo is (...) (22 years ago, 5-Sep-02, to lugnet.cad.ray)

| | | | | (...) Hi Richard, Do not blame Lars. Look at the contents of the 4869.dat file and try to replace this line 1 16 0 0 -52 1 0 0 0 0 1 0 1 0 stud.dat by this line 1 16 0 0 -52 1 0 0 0 0 -1 0 1 0 stud.dat Does this solve your problem?

One of them will have correct logos, the other won't, because (...) (22 years ago, 6-Sep-02, to lugnet.cad.ray)

I get it if you mean that someone manually mirrored aspects of the DAT file without regard to how the stud would turn out at L3P quality level 3 -- so I (...)

| | | | | | | (...) Something about MLCad that's worth noting is that fact that when you add a new part is uses the same rotation matrix as the part above it. Therefore, if you mirrored the part above the part you just added, the part you added is mirrored as (...) (22 years ago, 6-Sep-02, to lugnet.cad.ray, lugnet.cad.mlcad)

So mirroring a stud primitive is logically identical to mirroring an entire part. BTW, (...) (22 years ago, 6-Sep-02, to lugnet.cad.ray)

| | | | (...) Considering the usefulness of modeling mirrored parts this way (one file just references the other file) (it saves time and bytes), I'd say this is a problem that needs resolution in software. I *think* it could addressed with a POV-Ray macro, (...) (22 years ago, 6-Sep-02, to lugnet.cad.ray)

Would it be possible to recreate the basic wing, without studs, as a sub-part, and then invoke it in the two actual wing files? The studs could be added in the (...)

For example, some parts (30373 is one of them) use mirror symmetry to create a subpart that is a fraction (like 1/4 or 1/8) of the (...) (22 years ago, 6-Sep-02, to lugnet.cad.ray)
