However, regarding the part being wrong to use SPHERICIAL, I think that you are wrong about that. The texture is definitely not designed to be used as a Mercator projection. Switching to CYLINDRICAL squishes everything vertically. And while I don't exactly understand why, the lines of latitude are correct with SPHERICAL projection in this part. (Just look at it directly from the side with the original SPHERICAL projection.) While using CYLINDRICAL with an appropriate texture would probably make more sense, the existing texture is definitely not right for that.
LDCad doesn't seem to be available on Mac, so I can't easily check.
A cylindrical projection is by definition one that keeps the lines of latitude parallel. So the texture is definitely designed to be used with a cylindrical projection. From the wikipedia page:
Quote:A normal cylindrical projection is any projection in which meridians are mapped to equally spaced vertical lines and circles of latitude (parallels) are mapped to horizontal lines.
LDView is I believe wrong in its decoding of the SPHERICAL type projection too.
