  • I had this problem in my job as a drafter. I was wondering why the hell Tekla would complain about the same object name already being in use despite everything having its own name. took me way too long to realize there wad some stupidly max name length and the program did nothing to alarm the user about trying to put too long name. it just cut the overflow away.

    I mean we do know the formula, se we know pretty well how accurate it was, since we can just use the same formula with meters and calculate it ourselves

    "The simplified method works by considering two cities along the same meridian and measuring both the distance between them and the difference in angles of the shadows cast by the sun on a vertical rod (a gnomon) in each city at noon on the summer solstice. The two cities used were Alexandria and Syene (modern Aswan), and the distance between the cities was measured by professional bematists.[16] A geometric calculation reveals that the circumference of the Earth is the distance between the two cities divided by the difference in shadow angles expressed as a fraction of one turn.
