Hi Karl.
I just printed the "H2 Top Plate LH" from the "Part 1 - #1 THR" folder. The measurements do not seem to be accurate to the real B737. I am basing this on the "B737 Flight Deck Measurements Information Sheet". For the most part the parts are 2mm off but the height is off by 6mm. I've provided a screenshot that shows the difference.

Hi Karl.
This link is useful if you're looking for measurements.

Hello Steve,
Thank you for pointing this out. This was a major point of contention when I started this website. In general, the cockpit dimensions are approximately 2mm out over the whole cockpit and there is the odd one or two up to 5mm out. This might help you to understand:
The cockpit was generally produced by friends who work on the 737 taking a direct photo like above with a tape measure. Instead of getting them to measure every single dimension, which would drive them insane, as I was already requesting 10-20 photos a day of particular items. They would slap a ruler or tape measure against the item and take a photo. The photo was then imported into fusion and the outline drawn against. This naturally generates errors due to parallax alignment etc. This produced good enough results for me and my build.
If you need precise mm dimensions, then this site can not currently offer that. However, as time progresses faster than ever as I get older, more information comes out such as the drawing above. Perhaps in Version 6, I can make a more precise model, until then I can only apologise for the differences.
Kind regards Karl
